Ozone Contrast Media in Digital Renal Angiography

Gadolinium-based contrast media compared with iodinated media for digital subtraction angiography in azotaemic patients.

BACKGROUND To determine whether gadolinium-based contrast media (CM) could be used safely for angiographies in patients with renal dysfunction we investigated renal function after gadobutrol exposure and compared the results with standard iodinated CM (iohexol) in a randomized clinical study. METHODS Twenty-one patients (aged 67+/-11 years, nine female and 12 male) with severely impaired rena...

Iso-Osmolar versus Low-Osmolar Contrast Media in Reducing Contrast Induced Nephropathy in Patient with Renal Impairment Undergoing Coronary Angiography

Contrast-enhanced MR angiography and digital subtraction angiography in living renal donors: diagnostic agreement, impact on decision making, and costs

Health technology The authors studied contrast-enhanced magnetic resonance angiography (MRA) and digital subtraction angiography (DSA). MR images were obtained using a 1.5-T MR scanner (Signa CV/I, GE Healthcare) with a torso phased-array coil. Digital subtraction images were obtained using a 38-cm field of view and an image matrix of 1,024 x 1,024 pixels (Integris V3000, Philips Medical System...

Are gadolinium-based contrast media really safer than iodinated media for digital subtraction angiography in patients with azotemia?

Gadolinium chelates, intended as intravenous contrast media for magnetic resonance imaging, have been regarded as nonnephrotoxic and recommended to replace iodinated contrast media in patients with azotemia who are undergoing digital subtraction angiography (DSA). High intraarterial doses (up to 220 mmol of gadodiamide) have been used, with a 40% incidence of nephropathy. The authors discourage...

Contrast-enhanced MR angiography and digital subtraction angiography in living renal donors: diagnostic agreement, impact on decision making, and costs.

OBJECTIVE The objective of our study was to evaluate the diagnostic agreement, the impact on decision making, and the costs of contrast-enhanced MR angiography and digital subtraction angiography in the workup of living renal donors. CONCLUSION Contrast-enhanced MR angiography for the preoperative evaluation of renal donors is superior to digital subtraction angiography in revealing vascular ...
