Free-Breathing 3D T1-Weighted Gradient-Echo Sequence With Radial Data Sampling in Abdominal MRI: Preliminary Observations

Abstract: A free-breathing radial 3D GRE sequence is feasible for abdominal MRI and may find application in imaging of patients who are unable to suspend respiration, especially children.

“…These factors have seen Radial-VIBE being routinely used in body and paediatric imaging. [5][6][7] However, evaluation of the orbit using Radial-VIBE has not been studied. The purpose of our study was to determine the role of contrast-enhanced Radial-VIBE in assessing the orbits and compare it with currently accepted clinical standard of care, including contrast-enhanced T1W MPRAGE WE and fatsuppressed 2D TSE images.…”

“…* Statistically significant CAIPIRINHA = controlled aliasing in parallel imaging results in a higher acceleration; CNR = contrast-to-noise ratio; GA = golden angle; GRE = gradient-recalled echo; ILAB = interleaved angle-bisection; SD = standard deviation; SI = signal intensity; SNR = signal-to-noise ratio; VIBE = volumetric interpolated breath-hold examination information and reduces the motion artifact (1,7,11,16). Therefore, the use of this technique could provide higher quality images, which could be especially useful in patients which have breath-holding difficulties or in those with poor compliance, despite requiring a substantial amount of acquisition time (17,18).…”

“…Using this technique, k-space lines are collected in a radial fashion, resulting in high sampling of the central k-space and motion artifact suppression (1,(11)(12)(13)(14)(15). There are two radial GRE sequences, the interleaved, anglebisection scheme (ILAB), and the golden-angle scheme (GA) (13).…”

“…Motion artifacts remain the major cause for study compromise if patients are not able to comply with breathholding. Recent developments, such as 3D-GRE with a radial K-space acquisition (Azevedo, 2011), have been shown to provide adequate motion resistant imaging in the abdomen. This sequence may also provide diagnostic images in the chest, in combination with a blood contrast agent such as gadofosveset trisodium, probably allowing motion-resistant steadystate contrast enhanced MRA of the chest.…”
