30-year-old woman with VHL syndrome and prior pancreatic surgery Axial diffusion-weighted images (b=100 s/mm2) (Figure 4.20.1) reveal multiple hyperintense hepatic lesions. Axial fat-suppressed FSE T2-weighted images (Figure 4.20.2) demonstrate extensive cystic disease involving the pancreas. Note also that several lesions consist of clustered cysts. Axial (...

70-year-old woman with a history of ovarian carcinoma Coronal SSFSE images (Figure 11.15.1) demonstrate a large, predominantly solid right adnexal mass, with a simple-appearing cystic lesion in the left ovary. Note the abdominal pelvic ascites and small solid nodules between the diaphragm and liver, as well as confluent omental masses below the transverse colon on the most anterior image. Axial diffusion-weighted images (b=600 s/mm...

61-year-old woman with a known syndrome Coronal SSFSE (Figure 4.17.1) and axial diffusion-weighted images (b=600 s/mm2) (Figure 4.17.2) demonstrate marked rugal fold thickening in the fundus and body of the stomach. A heterogeneous hypoenhancing mass at the neck of the pancreas is seen on arterial phase postgadolinium 3D SPGR images (...

31-year-old man with abdominal pain Axial diffusion-weighted images (b=100 s/mm2) (Figure 2.18.1) reveal no normal hepatic veins, prominent collateral veins in the periphery of the liver, and a small tangle of collateral vessels anterior to the IVC. Notice also small, hyperintense filling defects in diminutive hepatic veins (confirmed on postgadolinium images). Coronal fat-suppressed 2D SSFP image (...

Low b-value (50–100) diffusion-weighted images detect significantly more hyperintense liver lesions in children than T2-weighted images
