Indications for Use
Your MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross-sectional images, spectroscopic images and/or spectra, and that displays the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These images and/or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis. Your MAGNETOM system may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room displays and MR Safe biopsy needles.
Device Story
MAGNETOM Vida is an MRI system; inputs include magnetic resonance signals from patient anatomy. New feature, MR Fingerprinting (MRF), uses a 2D FISP pulse sequence to acquire data for simultaneous non-invasive quantification mapping of T1 and T2 relaxation times in brain tissue. System operated by healthcare professionals in clinical settings. Output consists of cross-sectional images, spectra, and derived parametric maps (T1/T2). Physician interprets output to assist in diagnosis. MRF provides quantitative tissue characterization; not intended as ground truth. System supports interventional procedures using MR-compatible accessories.
Clinical Evidence
Clinical data included a study of 3 healthy volunteers scanned multiple times across multiple systems to assess repeatability and reproducibility of T1/T2 maps. Longitudinal clinical patient cases were provided to demonstrate repeated scan utility. Bench testing included phantom studies for quantitative evaluation of T1/T2 values and software verification/validation. Results confirmed successful sequence execution, image quality without artifacts, and stable, reproducible parametric values.

{5}------------------------------------------------
# SIEMENS Healthineers
#### 510(k) Summary - K213805
what is currently offered in the predicate devices, MAGNETOM Vida with syngo MR XA31A (K203443) and MAGNETOM Vida with syngo MR XA20A (K192924) respectively.
The subject devices MAGNETOM Vida with software syngo MR XA31A, and MAGNETOM Vida with synqo MR XA20A includes features that were cleared under K203443 and K192924 respectively. In addition to these features, the subject devices include a new pulse sequence type called MR Fingerprinting (MRF), a method that permits the simultaneous non-invasive quantification mapping of MRF-derived T1 and T2 relaxation times of brain tissue. The MRF is not intended to yield the ground truth T1 and T2 relaxation times of brain tissue.
## 7. Substantial Equivalence
MAGNETOM Vida with software syngo MR XA31A and the pulse sequence MRF is substantially equivalent to the following predicate device:
| Predicate Device | FDA Clearance Number<br>and Date | Product<br>Code | Manufacturer |
|--------------------------------------|------------------------------------|-----------------|----------------------------|
| MAGNETOM Vida with<br>syngo MR XA31A | K203443,<br>cleared March 31, 2021 | LNH<br>LNI, MOS | Siemens Healthcare<br>GmbH |
MAGNETOM Vida with software syngo MR XA20A and the pulse sequence MRF is substantially equivalent to the following predicate device:
| Predicate Device | FDA Clearance Number<br>and Date | Product<br>Code | Manufacturer |
|--------------------|------------------------------------|-----------------|--------------------|
| MAGNETOM Vida with | K192924,<br>cleared March 11, 2020 | LNH | Siemens Healthcare |
| syngo MR XA20A | | LNI, MOS | GmbH |
The software sequence for MRF is identical in the device software versions syngo MR XA31A and syngo MR XA20A.
## 8. Technological Characteristics
The MR Fingerprinting (MRF) is the one new function within software versions synqo MR XA20A and synqo MR XA31A for MAGNETOM Vida.
There are differences in technological characteristics between the subject devices and predicate devices. The underlying software (syngo MR XA20A and synqo MR XA31A) are identical to the predicate, and the inclusion of MRF is the only difference in terms of technological characteristics.
The subject device conforms to the standard for medical device software (IEC 62304) and other relevant IEC and NEMA standards
{6}------------------------------------------------
#### 9. Nonclinical Tests
The following performance testing was conducted on the subject device.
| Performance Test | Tested Software | Source/Rationale |
|-----------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------|
| Sample clinical images | New feature "MR Fingerprinting"<br>with the new 2D FISP MR-<br>Fingerprinting pulse sequence<br>type as part of the software<br>version syngo MR XA20A and<br>syngo MR XA31A*. | Submission of Premarket<br>Notifications for Magnetic<br>Resonance Diagnostic Devices<br>(November 2016) |
| Performance bench test | Phantom and volunteer testing<br>for quantitative evaluation of<br>MRF-derived T1 and T2 values | |
| Software verification and<br>validation | New feature "MR Fingerprinting"<br>with the new 2D FISP MR-<br>Fingerprinting pulse sequence<br>type as part of the software<br>version syngo MR XA20A and<br>syngo MR XA31A. | Guidance for the Content of<br>Premarket Submissions for<br>Software Contained in Medical<br>Devices (May 2005) |
* The tests were performed with the MR Fingerprinting (MRF) software sequence implemented in syngo MR XA20A. As the MR Fingerprinting (MRF) software sequence is identical between syngo MR XA20A and syngo MR XA31A, the clinical results are also valid for syngo MR XA31A.
For the performance test 'Sample clinical images', MRF T1 and T2 maps from volunteers were acquired to confirm the MRF sequence was executed successfully, and the resulting images were free of any obvious artifacts or degradations.
For the 'Performance bench test' repeated MRF T1 and T2 maps were acquired as part of a controlled study setup in phantom and healthy volunteers to evaluate the quantitative performance in terms of precision (repeatability and reproducibility).
The process 'Software verification and validation' comprises systematic testing according to the MRF test specification. MRF T1 and T2 maps were retrieved using on a quantitative phantom to confirm that the results were stable and parametric values were reproducible across different systems within specified ranges.
The results from each set of tests demonstrate that the devices perform as intended and is thus substantially equivalent to the predicate devices to which they have been compared.

### 10. Clinical Tests
A study was performed with 3 healthy volunteers who were scanned multiple times using multiple systems to show the repeatability and reproducibility of the T1 and T2 maps acquired on the subject device and other MAGNETOM 3T scanners. In addition, several clinical patient cases were provided which demonstrated a longitudinal use case scenario, i.e., repeated scans from the same subject to observe changes over time.
The tests were performed with the MR Fingerprinting (MRF) software sequence implemented in syngo MR XA20A. As the MR Fingerprinting (MRF) software sequence is identical between syngo MR XA20A and syngo MR XA31A, the clinical results are also valid for syngo MR XA31A.
Clinical publications were referenced to provide additional clinical information on the new MR Fingerprinting method.
#### 11.Safety and Effectiveness
The device labeling contains instructions for use and any necessary cautions and warnings to ensure safe and effective use of the devices.

## 12.Conclusion to Substantial Equivalence
MAGNETOM Vida with software syngo MR XA31A and the new pulse sequence MRF has the same intended use and similar technological characteristics compared to the predicate device, MAGNETOM Vida with syngo MR XA31A (K203443), with respect to the magnetic resonance features and functionalities. Similarly, MAGNETOM Vida with software syngo MR XA20A and the new pulse sequence MRF has the same intended use and similar technological

# SIEMENS Healthineers
characteristics compared to the predicate device MAGNETOM Vida with syngo MR XA20A (K192924).
The difference between the subject device and predicate device is the addition of the new pulse sequence "MRF". The difference has been tested and the conclusions from the non-clinical and clinical data suggests that the feature bears an equivalent safety and performance profile to that of the predicate device.
Siemens believes that the addition of the new pulse sequence "MRF" to MAGNETOM Vida with software syngo MR XA31A and MAGNETOM Vida with software syngo MR XA20A is substantially equivalent to the currently marketed devices MAGNETOM Vida with software syngo MR XA31A (K203443, cleared on March 31, 2021) and MAGNETOM Vida with software syngo MR XA20A (K192924, cleared on March 11, 2020) respectively.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
