Regenerative nodules in hepatic cirrhosis. Value of gradient-echo MR imaging with a surface coil.

To evaluate the accuracy of surface coil gradient-echo (GRE) imaging in the detection of regenerative nodules of hepatic cirrhosis, 53 patients with diffuse liver disease, among whom 31 had cirrhosis, were prospectively investigated. Three GRE sequences acquired with a surface coil were used in the study: a T2*-weighted, a T1-weighted, and a gadopentetate-enhanced sequence. ROC analysis showed that two surface coil GRE sequences were superior to conventional T2-weighted spin-echo imaging acquired with a body coil for the detection of regenerative nodules. The detection of regenerative nodules was also more accurate for the diagnosis of cirrhosis than the measurement of the caudate-to-right lobe ratio. These results suggest that there could be a potential for surface coil GRE imaging in the assessment of the characteristic macroscopic alterations of cirrhosis.

Recurring Filling Defect of the Renal Pelvis - Keratinising Desquamative Squamous Metaplasia (kdsm)

The authors report a case of keratinising desquamative squamous metaplasia (KDSM) and review the literature on the topic. The aetiology and clinical-radiological characteristics are described and the long-term (8 years) efficiency of percutaneous treatment is emphasised.

Abdominal Doppler and Color Doppler Ultrasound Studies with Emphasis on Liver Vessels: Experience with 2000 Examinations

We have reviewed the records of some 2000 consecutive examinations of patients who underwent abdominal duplex pulsed Doppler and/or color Doppler sonography. Of these, 1850 examinations were performed for liver vessel investigation (e.g., diffuse liver pathology, workup of liver transplantation) and 284 for other reasons. The latter included 140 examinations for renal vascularization (e.g., transplantation, pre- and postdilation control of renal artery disorder), 102 for suspected thrombosis of the vena cava and/or iliac veins, and 42 for diseases of the aorta and/or its branches (e.g., splenic arteries, superior mesenteric arteries), follow-up after aortofemoral prosthesis, and differential diagnosis between vascular and nonvascular pathology.
