Olympics Radcast 2002

Nov 20, 2003

A GE Medical Systems 1.5 Tesla mobile Signa Infinity EchoSpeed MR suite is housed in a semi-trailer setup approximately 100 feet from the entrance to the Olympic Polyclinic. The system includes a magnet and electronics that were installed in the trailer by the van manufacturer (AK Specialty Vehicles in Chicago) and are fully calibrated by GE Medical Systems' MR mobile manufacturing group.

Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
