“…Following a 2‐week washout period, 3D‐TOF‐MRAs and VWI were reviewed together to identify vessel wall enhancement or luminal narrowing. Following published methods, enhancement was visually determined by comparing the pre‐ and postcontrast acquisitions . Twenty‐three intracranial segments were evaluated (paired internal carotid artery (ICA) termini, anterior cerebral (A1, A2, A3), middle cerebral (M1, M2, M3), posterior cerebral (P1, P2, P3), intradural vertebral, and basilar arteries.…”

METHODS: Ninety-three consecutive subjects with a clinical history of suspected vasculopathy imaged with both VWI and 3D-TOF-MRAs were retrospectively reviewed. The 3D-TOF-MRAs were reviewed by two independent neuroradiologists classifying arterial segments as normal or abnormal based on caliber changes. Following a 2-week wash-out period, the 3D-TOF-MRAs with VWI together were re-evaluated for caliber changes and/or vessel wall enhancement. A third neuroradiologist served as consensus. Significance was assessed by McNemar's test. RESULTS:Forty-two subjects with VWI and 3D-TOF-MRAs met the inclusion criteria. By 3D-TOF-MRA alone, 12.3% (95% confidence interval [CI], 10.7-15.1) of the arterial segments were identified as abnormal compared to 20.8% (95% CI, 18.2-23.4) by VWI and 3D-TOF-MRA together (P < .0001). CONCLUSIONS: 3D-TOF-MRA and VWI together identifies a higher number of abnormal vessel segments than 3D-TOF-MRA alone and may provide a more accurate assessment of disease burden.

“…Imaging is extremely valuable in the diagnosis of PACNS. As well as the traditional technologies of CT, MRI, and cerebrovascular imaging, such as computed tomography angiography (CTA), MRA, and digital subtraction angiography (DSA), the diagnosis of PACNS with various other imaging techniques has been reported, including new molecular imaging procedures [16][17][18] . Most PACNS patients have various MRI abnormalities 19 , but some PACNS patients have normal angiograms 20 .…”

“…MRA and DSA examinations of PACNS patients can detect stenosis or dilation of multisegment blood vessels in ischemic lesions, but rarely nd long, complete vascular occlusions or aneurysm-like changes 1,6 . Until recently, DSA was the most widely used technique to diagnose PACNS 6,18,21 . The most typical manifestations of PACNS on MRI are multiple asymmetric ischemic lesions involving the bilateral cerebral hemispheric cortex, subcortical structure, and deep white matter, accompanied by intracerebral or subarachnoid hemorrhage.…”

Objective To determine the role of diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) imaging to guide stereotactic biopsy for the diagnosis of intracranial angiitis. Case presentation In a 28-year-old woman who had experienced inactive headache and right limbs numbness for 4 days, preoperative magnetic resonance (MR) scanning, enhanced scanning, diffusion tensor imaging, magnetic resonance spectroscopy, diffusion-weighted imaging (DWI), and ADC image scanning were performed. Stereotactic biopsy was performed in one target where the area of edema detected with MR FLAIR, and two targets where the area shown as a high-value and a lower-value area in the DWI/ ADC image. Pathological examinations together with computed tomographic and enhanced MRI scans were conducted after surgery. A preoperative enhanced MRI scan showed a uniform low-intensity lesion in the patient’s left centrum semiovale, with a volume of 3.1 cm3. The DWI and ADC images showed uneven high-intensity signals and different ADC values in the lesion area, respectively. During surgery, tissues around the lesion and the lesion center were sampled at the three selected targets. The postoperative pathological diagnosis was primary angiitis of the central nervous system, and the patient was given anti-inflammatory medication and hormone therapy. The 3-year follow-up confirmed that the patient had recovered well, with a Glasgow Outcome Scale score of 5. Conclusion DW-MRI and ADC images can be reliably used to determine the location of small intracranial lesions, and guide stereotactic biopsy to facilitate the diagnosis of primary vasculitis of the central nervous system.

“…Survey of studies focused on 1 vasculopathy revealed intracranial atherosclerotic disease (ICAD) to be the most commonly studied vasculopathy (49%, n = 62, references in the On-line Appendix), followed by arterial dissection (13%, n = 16), 10,12 -26 aneurysm (8%, n = 10), [27][28][29][30][31][32][33][34][35][36] vasculitis (5%, n = 6), [37][38][39][40][41][42] Moyamoya disease (3%, n = 4), [43][44][45][46] postendovascular changes (2%, n = 3), [47][48][49] and reversible cerebral vasoconstriction syndrome (1%, n = 1) 50 ( Fig 3C). Among the 16 publications investigating arterial dissections, 11 used VWI 12,[14][15][16][17][18][22][23][24][25][26] and the other 5 publications 10,13,[19][20][21] assessed intramural hematoma signal characteristics on conventional MR imaging.…”

BACKGROUND: Over the last quarter-century, the number of publications using vessel wall MR imaging has increased. Although many narrative reviews offer insight into technique and diagnostic applications, a systematic review of publication trends and reporting quality has not been conducted to identify unmet needs and future directions. PURPOSE: We aimed to identify which intracranial vasculopathies need more data and to highlight areas of strengths and weaknesses in reporting. DATA SOURCES: PubMed, EMBASE, and MEDLINE databases were searched up to September 2018 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA ANALYSIS: Two independent reviewers screened and extracted data from 128 articles. The Strengthening the Reporting of Observational Studies in Epidemiology guidelines were used to assess the reporting quality of analytic observational studies.
