Optellum Virtual Nodule Clinic vs Tempus AI Imaging
Tempus Pixel's own footnote says its cleared Lung module (K203744) is not indicated for lung nodule detection, and that nodule detection in the US comes from third-party engines, Infervision's InferRead CT (K192880) among them. Optellum's K202300 covers tracking, assessment and characterization of incidentally detected pulmonary nodules, including a lung cancer risk score, and the vendor lists integration with RapidAI's Rapid Enterprise platform. A nodule clinic that wants a cleared lung cancer risk score buys Optellum, whose K202300 names the LCP-CNN score. Pixel's page lists lung nodule detection, quantification and tracking, and its Lung module (K203744) is not indicated for detection, so for that clinic Pixel is the weaker fit.
Oncology imaging services that want lesion segmentation and tumor response reporting on CT and MR, and cardiology groups reading cardiac MR, are Pixel's customers. Pixel also generates T1 and T2 inline maps from raw MRI data.
