چکیده

(A) TWIST image in early arterial phase showing capillary lakes (arrow head). (B) TWIST image 2.2 sec after (A) showing development of tiny early draining veins (arrow). (C) Standard 3d ceMRA in the arterial phase demonstrating significant venous contamination without evidence of capillary shunting.

Purpose. The aim of this study was to assess the correlation of 3D time-of-flight MR angiography (TOF MRA) and contrast-enhanced MR angiography (CEMRA) for carotid artery stenosis evaluation at 3T. Material and Methods. Twenty-three patients (5 f, 18 m; mean age 61 y, age range 45-78 y) with internal carotid artery stenosis detected with ultrasonography were examined on a 3.0T MR system. The MR...

Low-dose Contrast-enhanced Magnetic Resonance Angiography with Less than the Standard Dose of Gadolinium Chelate: Comparison with Conventional Digital Subtraction Angiography

angiography, various performance enhancing MR sequences and scanning protocols have been adopted (17). The development of higher performance MR scanners has facilitated these trials (5, 8, 9), and contrast-enhanced MR angiography (CEMRA) has thus become a feasible method of vascular imaging. Various amounts of contrast media have been used for CEMRA, ranging from the standard dose of 0.05 mmol ...

Congenital Heart Disease: Role of Time-Resolved MR Angiography

Background and Objective: Cardiac MRI and contrast-enhanced MR angiography (CE-MRA) are gaining interest as non-invasive diagnostic measures for both primary diagnosis and follow up of patients with congenital heart disease (CHD) (1). Due to the presence of complex anatomy and extensive collateral pathways between pulmonary and systemic circulation in patients with CHD, a highly temporally reso...
