We have devised a modified Dixon method for analyzing fatty infiltration of the liver using a dual doublegradient-echo (DDGRE) sequence. To correct the T2* decay, fourfold echo images were obtained by out-of-phase (TE = 2.3/6.9 ms) and in-phase (4.6/9.2 ms) double-echo sets during a single breath-hold scan on a 1.5 T MRI. The liver fat fractions obtained using the DDGRE method were determined i...

INTRODUCTION: Rotator cuff tears (RCT) are the most common tendon injury seen in orthopedic patients. Although small tears are amenable to arthroscopic repair, massive RCT repairs can result in re-tears and poor clinical outcomes. Muscle atrophy and fatty infiltration in rotator cuff muscles are major complications of chronic massive RCT and are thought to be among the factors responsible for t...

Marked peritoneal thickening extending into the mesentery can occur with malignant infiltration but is usually very nodular and distributed irregularly. Pseudomyxoma peritonei can produce diffuse generalized infiltration in the mesentery and surrounding the liver and spleen, but on CT has a low attenuation similar to ascites. Tuberculous peritonitis classically produces generalized, diffuse per...

BACKGROUND AND AIMS To prospectively determine the accuracy of liver fat quantification with magnetic resonance imaging (MRI). PATIENTS AND METHODS The population consisted of 40 patients (mean age, 52.5 years; range, 23-78 years). The same day, all patients underwent MRI and ultrasonography-guided liver biopsy. The histological evaluation of steatosis was performed by an experienced liver pa...

lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. the affected nerve becomes thicker, and it simulates a mass lesion. lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. magnetic resonance imaging (mri) is the key to diagnosis, and it is usually pathognomoni...
