High resolution unenhanced computed tomography in patients with swollen legs.

Purpose: To evaluate the accuracy of computed tomography (CT) scan imaging in distinguishing lymphedema from deep venous thrombosis (DVT) and lipodystrophy (lipedema) in patients with swollen legs.

Material And Methods: CT scans of the lower limbs were performed in 55 patients with 76 swollen legs (44 lymphedemas, 12 DVT and 20 lipedemas). Thirty-four normal contralateral legs were also similarly evaluated.

Acute colonic diverticulitis: prospective comparative evaluation with US and CT.

Purpose: To compare the accuracy of ultrasonographic (US) and computed tomographic (CT) findings for diagnosis of acute colonic diverticulitis.

Materials And Methods: US and CT were prospectively performed in 64 consecutive patients suspected of having acute colonic diverticulitis. Images were interpreted independently in a blinded fashion.
