What FDA granted it for
The Indications for Use statement, verbatim, from the decision document.
QuantX is a computer-aided diagnosis (CADx) software device used to assist radiologists in the assessment and characterization of breast abnormalities using MR image data. The software automatically registers images, and segments and analyzes user-selected regions of interest (ROI). QuantX extracts image data from the ROI to provide volumetric analysis and computer analytics based on morphological and enhancement characteristics. These imaging (or radiomic) features are then synthesized by an artificial intelligence algorithm into a single De Novo Summary DEN170022 value, the QI score, which is analyzed relative to a database of reference abnormalities with known ground truth. QuantX is indicated for evaluation of patients presenting for high-risk screening, diagnostic imaging workup, or evaluation of extent of known disease. Extent of known disease refers to both the assessment of the boundary of a particular abnormality as well as the assessment of the total disease burden in a particular patient. In cases where multiple abnormalities are present, QuantX can be used to assess each abnormality independently. This device provides information that may be useful in the characterization of breast abnormalities during image interpretation. For the QI score and component radiomic features, the QuantX device provides comparative analysis to lesions with known outcomes using an image atlas and histogram display format. QuantX may also be used as an image viewer of […]

Adverse-event reports in MAUDE, by product code
As of , MAUDE held 1 report filed against devices carrying product code POK. That code is shared by every device of this type, not this device alone, and MAUDE reports are submitted by manufacturers, facilities and the public without FDA verification. The latest reports, in the reporter’s words:
15 January 2021 · Malfunction · QUANTX · report MW5098869
QUANTX SOFTWARE MAY ENTER INTO AN ERROR STATE IN WHICH MEDICAL IMAGES DISPLAYED TO THE USER ARE FROZEN IN PLACE. QUANTX SOFTWARE VERSION (B)(4) ENTER INTO AN ERROR STATE IN WHICH ONE VIEWPORT IS FROZEN IN PLACE. WHEN THIS ERROR OCCURS, QUANTX STOPS RESPONDING TO USER INPUTS TO MODIFY THE DISPLAY OF THE FROZEN IMAGE. THIS ERROR STATE IS REACHED THROUGH A SPECIFIC SEQUENCE OF KEYSTROKES AND MOUSE ACTIONS. ONCE THE ONE IMAGE IS FROZEN IN A VIEWPORT IT REMAINS FROZEN. IT WILL ALSO REMAIN FROZEN IF […]
