Gadopentetate dimeglumine-enhanced chemical-shift MR imaging of the breast.

Gadopentetate dimeglumine-enhanced MR imaging of spinal dermal sinus tract.

Spinal cord pial metastases: MR imaging with gadopentetate dimeglumine.

The purpose of this investigation was to describe gadopentetate-dimeglumine-enhanced MR findings in metastatic disease to the pial lining of the spinal cord. Correlation was made with clinical data, other radiologic studies, and pathologic findings. Eighty-six patients with a known malignancy and unexplained neurologic signs or symptoms were studied with pre- and postcontrast T1-weighted images...

Benign lumbar arachnoiditis: MR imaging with gadopentetate dimeglumine.

MR imaging was performed in 13 patients with benign lumbar arachnoiditis both before and after IV injection of gadopentetate dimeglumine. The arachnoiditis was proved by previous myelography in 12 patients and by noncontrast MR imaging in one patient. The disease was presumably the result of previous myelography and/or surgery. It was characterized as mild in two patients, moderate in two patie...

Gadopentetate-dimeglumine-enhanced MR imaging of gliomatosis cerebri: appearance mimicking leptomeningeal tumor dissemination.

The term gliomatosis cerebri was first used by Nevin in 1938 (1] and represents a neoplastic process of glial origin characterized by its diffuse pattern of infiltration along anatomic pathways [1 , 2]. Radiologic methods of detecting gliomatosis cerebri have relied heavily on CT [3-6]. Recently, the efficacy of MR imaging in detecting this disease has been described [7, 8]. We report a case of...

Contrast Enhanced 3D MR Angiography: Gadopentetate dimeglumine (Gd-DTPA) vs Gadobenate dimeglumine (Gd-BOPTA)

A randomized double-blind crossover comparison of 0.2 mmolikg Gd-DTPA and 0.1 mmolikg Gd-BOPTA was performed in 25 patients for MRA of the aorta and sopra aortic trunk, and the renal, mesenteric, lumbar, iliac and femoral arteries. Blinded qualitative evaluation by two radiologists revealed no differences in terms of lesion size, signal intensity or degree of stenosis. The results indicate that...
