Indications for Use
The device is indicated for use as a magnetic resonance diagnostic device software application for non-invasive assessment of liver health and the generation, display and review of magnetic resonance medical image data. The device produces quantified metrics and composite images from magnetic resonance medical image data which, when interpreted by a trained healthcare professional, yield information on liver tissue characteristics that may assist in clinical decisions.
Device Story
LiverMultiScan (v6.0) is a standalone software-as-a-medical-device (SaMD) for post-processing DICOM 3.0 MR image datasets. It processes images acquired from 1.5T or 3T MRI scanners (GE, Siemens, Philips) using MOLLI, NOLLI, MOST, or IDEAL acquisition methods. The software performs automated liver segmentation and region-of-interest analysis to quantify three metrics: iron-corrected T1 (cT1) for fibro-inflammatory activity, proton density fat fraction (PDFF) for fat content, and liver iron concentration (LIC). Perspectum-trained analysts operate the software to generate outputs, which are then interpreted by healthcare professionals to assist in clinical decision-making regarding liver pathology. The device provides standardized metrics across different scanner platforms, aiding in the assessment of steatosis, iron overload, and fibro-inflammation.
Clinical Evidence
Bench testing only. Performance validated using phantom and in-vivo data across Siemens, GE, and Philips 1.5T/3T scanners. Testing confirmed substantial equivalence for cT1 measurements between MOLLI and NOLLI methods. Metrics evaluated include repeatability, reproducibility, and inter/intra-operator variability. Comparative testing performed against a gold standard (mean of 3 radiologists). All tests met defined acceptance criteria.
Technological Characteristics
Standalone SaMD; processes DICOM 3.0 MR datasets. Supports 1.5T and 3T field strengths. Acquisition methods: MOLLI, NOLLI, MOST, IDEAL. Quantifies cT1, PDFF, and LIC. Standardized output across different MRI scanner manufacturers (GE, Siemens, Philips).
Indications for Use
Indicated for non-invasive assessment of liver health in the general population using magnetic resonance imaging. No demographic or population restrictions. Contraindications: None.

Dear Bhaskar Chikkanna:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

# 3 Subject Device Description
## 3.1 General Description
LiverMultiScan is a standalone, post processing software as a medical device (SaMD). It enables the generation, display and review of magnetic resonance (MR) medical image data for non-invasive assessment of liver health based on imaging acquired during a single patient visit.
LiverMultiScan quantifies liver tissue characteristics from appropriately acquired MR datasets. It produces three quantitative metrics: iron-corrected T1 (cT1): which reflects fibro-inflammatory disease activity of the liver parenchyma, proton density fat fraction (PDFF): a measure of liver fat content, and liver iron concentration (LIC). Each of these metrics is standardized to a single reference, ensuring that reference ranges and clinical thresholds can be applied consistently, regardless of the MRI scanner used to acquire the measurement. cT1, PDFF and LIC all have a valid and well-founded correlation with liver histology and are associated with pathological processes such as fibro-inflammation, steatosis, and iron overload, respectively.
