AI-Rad Companion Prostate MR

Siemens Healthineers
AI-Rad Companion Prostate MR (VA40) supports prostate MRI reading and reporting. By deploying artificial intelligence, the products assists in the interpretation of multiparametric Prostate MRI. The deep neural networks of Prostate MR are designed to aid the detection and classification of prostate lesions and generate a pre-populated report. Additionally it aims to aid the MR/US fusion for biopsy workflow by automatically segmenting the prostate and performing volumetry of the prostate gland. The results can be exported as a RTSS object which is then used in TRUS-guided biopsy by the urologist.
* In the United States, the VA30 is the commercially available version. This version does not include automated lesion detection and pre-populated PI-RADS report.
