3D contrast-enhanced MRA of the runoff vessels: value of image subtraction
نویسندگان
چکیده
Introduction: Diagnostic accuracy and cost will determine the success of contrast-enhanced 3D MRA in replacing catheter-based digital subtraction angiography (DSA) as the modality of choice for assessing the peripheral run-off arteries. Image subtraction, proposed by some investigators as a way to enhance diagnostic accuracy (1) lengthens data acquisition and post-processing times and therefore contributes toward a considerable increase in cost.

Contrast-enhanced MR angiography of intracranial giant aneurysms.
BACKGROUND AND PURPOSE Intravoxel phase dispersion and flow saturation often prevent adequate depiction of intracranial giant aneurysms on 3D time-of-flight (3D-TOF) MR angiography (MRA). Additional diagnostic difficulties may arise from T1 contamination artifact of an associated blood clot. Our aim was to assess whether contrast-enhanced MRA could improve the evaluation of giant aneurysms and ...
متن کاملExploiting sparsity in the difference images to achieve higher acceleration factors in non-contrast MRA
Introduction: It has recently been discovered that patients with renal insufficiency who receive large doses of gadolinium-based contrast agents may be at risk of a rare but serious disorder known as nephrogenic systemic fibrosis (NSF). This has spurred a search for alternatives to conventional first-pass gadolinium-enhanced MRA. Among the methods proposed for non-contrast peripheral MRA are EC...
متن کاملHigh spatial and temporal resolution dynamic contrast-enhanced magnetic resonance angiography (CE-MRA) using compressed sensing with magnitude image subtraction
PURPOSE We propose a compressed-sensing (CS) technique based on magnitude image subtraction for high spatial and temporal resolution dynamic contrast-enhanced MR angiography (CE-MRA). METHODS Our technique integrates the magnitude difference image into the CS reconstruction to promote subtraction sparsity. Fully sampled Cartesian 3D CE-MRA datasets from 6 volunteers were retrospectively under...
متن کاملSubtraction in View-Shared 3D Contrast-Enhanced MRA
INTRODUCTION The use of a pre-contrast reference image, referred to as a mask, to suppress background signal and improve output contrast-to-noise ratio (CNR) through subtraction is common in contrast-enhanced MR angiography. It is critical that this operation be performed to optimize output image quality. As has been previously reported [1-3] it is advantageous to use complex subtraction for th...
متن کاملMR angiography at 3T versus digital subtraction angiography in the follow-up of intracranial aneurysms treated with detachable coils.
BACKGROUND AND PURPOSE Digital subtraction angiography (DSA) is used to follow-up intracranial aneurysms treated with detachable coils to identify recurrence and determine need for additional treatment. However, DSA is invasive and involves a small risk of neurologic complications. We assessed the feasibility and usefulness of 3D time-of-flight (TOF) MR angiography (MRA) performed at 3T compare...
