The presence of acute ischemic lesions only in DWI can help to identify both lacunar and nonlacunar stroke patients who are in the 4.5 h time window for intravenous thrombolysis with high specificity.

Tractography-based measurements have sufficient reproducibility for demonstration of severe abnormalities of the cingulum. TBCA is preferential for clinical FA analysis, because it measures corresponding areas in patients and controls without inaccuracies due to trauma-induced structural changes.

According to past reports, many VA anomalies could be attributed to congenital or acquired conditions (e.g., rheumatoid arthritis). However, VA anomalies appear to exist even in patients without any such cervical diseases.

Our study suggests that distal stenting in wide-necked aneurysms is a reasonable alternative to traditional stent protection, despite the potential for delayed stent migration.

While a thrombosed single-rooted RMV typically becomes anatomically and angiographically undetectable, double-rooted MRVs keep a flowing proximal segment made of their two rootlets of origin. This residual proximal segment takes the appearance of an arrow-tip loop, which therefore be seen as an indicator of spinal venous thrombosis.

Changes in the skull base and craniofacial axis symmetry are due to structural and functional relationships between “major” and “minor” skull sutures, suggesting a structural and functional relationship between the neurocranium and basicranium. The early recognition of prematurely closed skull base sutures may help clinicians and neurosurgeons to establish correct therapeutic approaches.

SWI depicts a higher number of draining vein compared to conventional MR pulse sequences. ASL is a sensitive approach in showing 100 % sensitivity in the detection of AV shunting and in the diagnosis of the pattern of venous drainage. The present findings suggest the added utility of both SWI and ASL in the assessment of AV shunting.

DWI and 1 H-MRS are imaging modalities that can detect minHE in children with liver cirrhosis and correlate well with parameters of NPT.
