“…The identification of the subintimal dissection is easier to diagnose with DSA, however the subadventitial dissection forming a pseudoaneurysm without narrowing the arterial lumen and flow impairment can be missed. 10 Vessel wall magnetic resonance imaging (VW-MRI) appears to be superior. 10 In addition in the presence of a complete vessel occlusion, the DSA has poor diagnostic value for dissection.…”

“…2 Dissections most commonly involve the dorsal wall of the supraclinoid ICA, horizontal (M1) segment of the middle cerebral artery (MCA), and intracranial (V4) segment of the vertebral arteries. 36 Intracranial dissections are rare and may cause stroke or subarachnoid hemorrhage, especially in young adults aged 20-50 years. 37 Dissections may be further categorized as subintimal or subadventitial, each with distinct clinical course and risks.…”

“…24 An intramural hematoma is a defining feature on MRI and will clearly display blood outside of the true lumen, with heavily T1-weighted sequences including MPRAGE representing the optimal means to visualize hematoma. 31,36,38 Furthermore, the presence of intramural hematoma signifies a dissection that is more likely to progress to an ischemic event, result in subarachnoid hemorrhage, or lead to the development of a pseudoaneurysm. 40 In the context of intracranial arterial dissection, high-resolution vwMRI sequences may allow more sensitive detection of dissections compared with angiographic imaging alone.…”

Free‐breathing three‐dimensional isotropic‐resolution MR sequence for simultaneous vessel wall imaging of bilateral renal arteries and abdominal aorta: Feasibility and reproducibility

Purpose: Many diseases can simultaneously involve renal arteries and the adjacent abdominal aorta. This study proposed a free-breathing threedimensional (3D) isotropic-resolution magnetic resonance sequence for simultaneous vessel wall imaging (VWI) of bilateral renal arteries and adjacent abdominal aorta. Methods: A respiratory-triggered isotropic-resolution sequence that combined the improved motion-sensitized driven-equilibrium (iMSDE) preparation with the spoiled gradient recalled (SPGR) readout (iMSDE-SPGR) was proposed for simultaneous VWI of renal arteries and abdominal aorta. The proposed iMSDE-SPGR sequence was optimized by positioning spatial saturation pulses (i.e., REST slabs) elaborately to further alleviate respiratory and gastrointestinal motion artifacts and selecting appropriate first-order gradient moment (m 1 ) of the iMSDE preparation. Thirteen healthy subjects and 13 patients with renal artery stenosis underwent simultaneous VWI with the optimized iMSDE-SPGR sequence at 3.0 T. Signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and morphology of renal arterial wall and aortic wall were measured. Reproducibility of intra-observer, inter-observer, and scan-rescan (n = 13 healthy subjects) in measuring SNR, CNR, and morphology was evaluated. For the reproducibility test, the agreement was determined using intraclass correlation coefficients (ICC), and the differences were compared using paired t-test or nonparametric Wilcoxon test when appropriate. Bland-Altman plots were used to calculate the bias between observers and between scans. Results:The proposed iMSDE-SPGR sequence was feasible for simultaneous VWI both in the healthy subjects and the patients. The sequence showed good to excellent inter-observer (ICC: 0.615-0.999), excellent intra-observer (ICC: 0.801-0.998), and scan-rescan (ICC: 0.768-0.998) reproducibility in measuring morphology, SNR, and CNR. There were no significant differences in SNR, CNR, and morphology measurements between observers and between scans (all p > 0.05). Bland-Altman plots showed small bias in assessing SNR, CNR, and morphology. Data conclusion: The proposed free-breathing 3D isotropic-resolution iMSDE-SPGR technique is feasible and reproducible for simultaneous VWI of bilateral renal arteries and adjacent abdominal aorta.
