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...
متن کاملTime-resolved contrast-enhanced 3D MR angiography.
An MR angiographic technique, referred to as 3D TRICKS (3D time-resolved imaging of contrast kinetics) has been developed. This technique combines and extends to 3D imaging several previously published elements. These elements include an increased sampling rate for lower spatial frequencies, temporal interpolation of k-space views, and zero-filling in the slice-encoding dimension. When appropri...
متن کاملTime-resolved contrast-enhanced MR angiography of spinal vascular malformations.
BACKGROUND AND PURPOSE The diagnosis of spinal vascular malformations may be challenging on conventional MR imaging because neither the location of the signal abnormality in the spinal cord nor the level of the abnormal flow voids correlates with the level of the fistula. We conducted a retrospective evaluation of the utility of using a time-resolved imaging of contrast kinetics sequence in the...
متن کاملTime-resolved contrast-enhanced MR angiography of intracranial lesions.
PURPOSE To determine if contrast-enhanced (CE) MRI of intracranial lesions benefits from time-resolved MR angiography (MRA) during contrast agent injection. MATERIALS AND METHODS For 126 patients with suspected intracranial lesions undergoing routine CE MRI at 3.0T (N = 88) or 1.5T (N = 38), time-resolved CE MRA (three-dimensional [3D] time-resolved imaging of contrast kinetics [TRICKS]) was ...
متن کاملIntracranial time-resolved contrast-enhanced MR angiography at 3T.
BACKGROUND AND PURPOSE A method is presented for high-temporal-resolution MR angiography (MRA) using a combination of undersampling strategies and a high-field (3T) scanner. Currently, the evaluation of cerebrovascular disorders involving arteriovenous shunting or retrograde flow is accomplished with conventional radiographic digital subtraction angiography, because of its high spatial and temp...
