CO2 and gadopentetate dimeglumine as alternative contrast agents for malfunctioning dialysis grafts and fistulas

Gadopentetate dimeglumine as an intradiscal contrast agent.

STUDY DESIGN Magnetic resonance discography using gadolinium as an intradiscal contrast agent was investigated in a prospective study. OBJECTIVE To evaluate the utility of magnetic resonance discography using gadolinium as an intradiscal contrast agent, as compared with the current standard of computed tomographic discography using intradiscal iodinated contrast agent. SUMMARY OF BACKGROUND...

Gadopentetate dimeglumine as a contrast agent in common carotid arteriography.

BACKGROUND AND PURPOSE Despite improvements in noninvasive imaging, some patients with contraindications to iodine-based contrast material still require angiography for the evaluation of carotid stenosis. Our aim was to assess the utility of gadopentetate dimeglumine as an intraarterial contrast agent in common carotid angiography. METHODS Twelve patients with suspected carotid artery stenosi...

MRI for detection of hepatocellular carcinoma: comparison of mangafodipir trisodium and gadopentetate dimeglumine contrast agents.

OBJECTIVE The purpose of our study was to compare the performance of mangafodipir trisodium (Mn-DPDP)-enhanced and dynamic gadopentetate dimeglumine-enhanced MRI for the detection of hepatocellular carcinoma. MATERIALS AND METHODS Forty-six patients with 96 hepatocellular carcinomas underwent Mn-DPDP- and gadopentetate dimeglumine-enhanced MRI. The MRI examination included unenhanced T2-weigh...

Adrenal venous sampling by using gadopentetate dimeglumine in patients with contraindications for iodinated contrast agents.

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...
