Abdominal imaging
-
To assess unenhanced and gadolinium-enhanced magnetic resonance (MR) imaging patterns of hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). ⋯ Gadolinium-enhanced T1-weighted MR imaging is a reliable method for evaluating the outcome of TACE treatment and is more accurate than unenhanced T2-weighted MR imaging.

A case study of a patient who presented with abdominal pain and a palpable mesogastric mass is discussed. Ultrasound and computed tomography (CT) demonstrated that the palpable mass was jejunojejunal intussusception of the small intestine. The lead point of the intussusception was a lipoma that appeared in the CT scan as a small intramural mass with an attenuation coefficient of fat.

Comparative Study
Liver MR imaging: comparison of respiratory triggered fast spin echo with T2-weighted spin-echo and inversion recovery.
The purpose of this study was to compare a fast spin-echo sequence combined with a respiratory triggering device (R. trig. FSE) with conventional T2-weighted spin-echo (CSE) and inversion recovery (STIR) sequences for the detection of focal hepatic lesions. ⋯ Compared with CSE and STIR, R. trig. FSE produces hepatic images of comparable resolution and detects an increased number of focal hepatic lesions in a shorter period of time.
