Intended Use

The syngo.CT Lung CAD device is a computer-aided detection (CAD) tool designed to assist radiologists in the detection of solid pulmonary nodules during review of multi-detector computed tomography (MDCT) examinations of the chest. The software is an adjunctive tool to alert the radiologist to regions of interest (ROI) that may have been initially overlooked. The syngo.CT Lung CAD device is intended to be used as a second reader after the radiologist has completed his/her initial read.

Device Story

syngo.CT Lung CAD is a software-based computer-aided detection (CAD) tool for thoracic CT examinations. It processes MDCT images (4+ detector rows) to identify solid pulmonary nodules (≥ 3 mm). The device functions as a second reader; it alerts radiologists to regions of interest (ROI) that may have been initially overlooked. It is operated by radiologists in a clinical setting. The device outputs CAD marks for suspected nodules, which are displayed via compatible visualization applications (e.g., syngo PET&CT Oncology). The radiologist evaluates these marks to inform clinical decision-making. The device does not alter original image data; it serves as an adjunctive tool to improve nodule detection sensitivity.

Clinical Evidence

Bench testing only. Performance evaluated via standalone testing comparing the subject device to the predicate. Metrics included sensitivity, false positive rates, and dismissibility of false positives. Verification and validation testing confirmed software specifications met acceptance criteria. No clinical prospective or retrospective studies were required.

Technological Characteristics

Software-based CAD tool for MDCT images. Operates on the syngo.via platform. Conforms to ISO 14971:2007 (risk management), IEC 62304:2006 (software lifecycle), and IEC 62366:2007 (usability). No patient-contacting materials. Designed for 4+ detector row CT scanners.

Indications for Use

Indicated for radiologists assisting in the detection of solid pulmonary nodules (≥ 3 mm, optimized for 3-10 mm) in MDCT chest examinations. Used as a second reader tool after initial radiologist review. Applicable to central/peripheral nodules and round/irregular contours; usable with or without contrast enhancement.

Regulatory Classification

## Safety and Effectiveness Information Supporting the Substantial Equivalence Determination

## Device Description

syngo.CT Lung CAD is a medical device that is designed to perform CAD processing in thoracic CT examinations for the detection of solid pulmonary nodules ≥ 3 mm in size. The device processes images acquired with Siemens multi-detector CT scanners with 4 or more detector rows.

The syngo.CT Lung CAD device supports the full range of nodule locations (central, peripheral) and contours (round, irregular). The detection performance of the syngo.CT Lung CAD device is optimized for nodules between 3 mm and 10 mm in size. Additionally, the syngo.CT Lung CAD device can be used in scans with or without contrast enhancement.

The device receives images via an input data interface, performs CAD processing and provides locations of suspected nodules as an output. Specific visualizations, such as the syngo PET&CT Oncology application (K093621) or equivalent Siemens products, should be used (but are not part of this clearance) to display the CAD marks. The syngo.CT Lung CAD device is intended to be used as a second reader only after the initial read is completed.

## Intended Use

The syngo.CT Lung CAD device is a computer-aided detection (CAD) tool designed to assist radiologists in the detection of solid pulmonary nodules during review of multi-detector computed tomography (MDCT) examinations of the software is an adjunctive tool to alert the radiologist to regions of interest (ROI) that may have been initially overlooked. The syngo.CT Lung CAD device is intended to be used as a second reader after the radiologist has completed his/her initial read.

## Safety and Effectiveness Information

Software design description, hazard analysis, and technical and safety information have also been completed and provided in support of this device. Risk management is ensured via the hazard analysis, which is used to identify potential hazards.
