Dedicated Calf MRA at 3T: Comparison of time-resolved MR Angiography with interleaved stochastic trajectories (TWIST) with standard high-resolution 3D contrast enhance MR Angiography (HR ceMRA)
¶ Figure 3: Calf station of left lower limb in patient with normal runoff arteries. (A) TWIST demonstrates focal occlusion of the distal anterior tibial artery (arrow) and a high grade stenosis of the distal posterior tibial artery (arrowhead) (B) HR ceMRA demonstrating normally appearing runoff arteries.

متن کاملSLINKY: More Understanding, Optimization and Application for High Resolution MRA
Introduction For non-contrast TOF MRA, sliding interleaved ky acquisition (SLINKY) can provide high quality image with suppressed slab boundary artifact (SBA). This is because the technique transforms the SBA into a series of ghosts, which are further suppressed in maximum intensity projection process. The transformation of the SBA can be realized and controlled by several SLINKY parameters, re...
متن کاملHigh resolution projection reconstruction MR imaging using FOCUSS
This paper is concerned about high resolution reconstruction of projection reconstruction MR imaging from angular under-sampled k-space data. A similar problem has been recently addressed in the framework of compressed sensing theory. Unlike the existing algorithms used in compressed sensing theory, this paper employs the FOCal Underdetermined System Solver(FOCUSS), which was originally designe...
متن کاملUsing high-resolution MR imaging at 7T to evaluate the anatomy of the midbrain dopaminergic system.
BACKGROUND AND PURPOSE Dysfunction of DA neurotransmission from the SN and VTA has been implicated in neuropsychiatric diseases, including Parkinson disease and schizophrenia. Unfortunately, these midbrain DA structures are difficult to define on clinical MR imaging. To more precisely evaluate the anatomic architecture of the DA midbrain, we scanned healthy participants with a 7T MR imaging sys...
متن کاملHigh-resolution pulmonary arterio- and venography using multiple-bolus multiphase 3D-Gd-mRA.
The purpose of this study was to demonstrate selective visualization of pulmonary arteries and veins with high spatial resolution for improved detection of vascular pathologies. Time-resolved pulmonary three-dimensional gadolinium-enhanced magnetic resonance angiograms (3D-Gd-MRA) were acquired with an ultrashort 3D fast low-angle shot (FLASH) sequence (TR/TE 2.3/0.9 msec) using asymmetric k-sp...
