B-mode (a–c) and strain ratio (d–f) images of a carcinoma of unknown type in the coronal (a, d), sagittal (b, e) and transverse (c, f) planes. In the strain images (d–f), the maximal principal strain ratios are superimposed on the B-mode images of the top row. The purple arrows indicate the lesion.

Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.

Angiograms of the right knee in a 76-year-old man with knee osteoarthritis. A) Before embolization, selective angiography of the common trunk of the superior lateral and superior medial genicular arteries shows hypervascular inflammatory blush (arrows). B) During embolization using ethiodized oil of the common trunk, the angiogram shows emulsion droplets (arrows). Image courtesy of Diagnostic and Interventional Imaging.
