“…The technique of VWI with a voxel size of less than 1 mm 3 is particularly advantageous for detecting the characteristic minute vascular changes of BBAs, which are often undetectable with conventional imaging methods [ 20 , 21 ]. Incorporating the black-blood imaging technique into VWI is critical in distinguishing BBAs from the blood signal within the lumen.…”

“…Incorporating the black-blood imaging technique into VWI is critical in distinguishing BBAs from the blood signal within the lumen. By suppressing the blood signal, this technique allows for increased contrast between the aneurysm and the surrounding tissues [ 20 , 21 ]. This allows for a clearer visualization of the BBAs, which may present with high signal intensity or contrast enhancement due to the dissection and associated hemorrhage, facilitating easier detection and characterization of the aneurysm.…”

Blood blister-like aneurysms (BBAs) are rare and challenging intracranial aneurysms. They pose significant diagnostic and surgical risks due to their delicate walls. Accounting for a small percentage of intracranial aneurysms, BBAs are pathologically pseudoaneurysms, often resulting from arterial dissection, with a high tendency to rupture. This report underscores the critical nature of BBAs by reviewing a case in which subarachnoid hemorrhage caused by a BBA rupture was difficult to diagnose with conventional imaging. We highlight the efficacy of three-dimensional (3D) high-resolution vessel wall imaging (VWI) in discerning the subtle vascular abnormality of BBAs. The integration of the black-blood imaging technique within VWI provides superior contrast between the aneurysm and surrounding tissues, facilitating clearer visualization of the aneurysmal wall. The use of 3D T1-weighted imaging provides intricate details of the vessel wall including its contrast enhancement, which is crucial for a comprehensive assessment of a ruptured aneurysm. This case is consistent with the existing literature, supporting the role of VWI in the identification of ruptured BBAs, an area with limited but growing information on its diagnostic value. VWI is precise and accurate in the preoperative diagnosis of BBAs, emphasizing its potential to improve patient management and outcomes, especially in conditions with high risks of morbidity and mortality.

“…Lastly, in patients with nontraumatic SAH and normal DSA, which account for 15–20% of cases, VW-MRI revealed abnormal findings in 82.4% of cases, suggesting the utility of this technique in this setting. Abnormalities included intracranial artery dissections, blood blister-like aneurysms, ruptured fusiform aneurysms and focal nodular wall enhancement [ 109 ].…”

Cerebrovascular diseases are a leading cause of disability and death worldwide. The definition of stroke etiology is mandatory to predict outcome and guide therapeutic decisions. The diagnosis of pathological processes involving intracranial arteries is especially challenging, and the visualization of intracranial arteries’ vessel walls is not possible with routine imaging techniques. Vessel wall magnetic resonance imaging (VW-MRI) uses high-resolution, multiparametric MRI sequences to directly visualize intracranial arteries walls and their pathological alterations, allowing a better characterization of their pathology. VW-MRI demonstrated a wide range of clinical applications in acute cerebrovascular disease. Above all, it can be of great utility in the differential diagnosis of atherosclerotic and non-atherosclerotic intracranial vasculopathies. Additionally, it can be useful in the risk stratification of intracranial atherosclerotic lesions and to assess the risk of rupture of intracranial aneurysms. Recent advances in MRI technology made it more available, but larger studies are still needed to maximize its use in daily clinical practice.

“…DANTE pulse is a continuous irradiation of short duration hard pulse with small flip angle, and it has been used for frequency selective excitation in NMR spectroscopy [ 21 ] and cardiac tagging [ 22 ]. Recently DANTE pulse is used for VW-MRI with the advantage of signal suppression of both blood flow and CSF signal [ 20 , 23 – 26 ]. CSF is known to affect vessel walls [ 27 ].…”

Vessel wall MR imaging (VW-MRI) has been introduced into clinical practice and applied to a variety of diseases, and its usefulness has been reported. High-resolution VW-MRI is essential in the diagnostic workup and provides more information than other routine MR imaging protocols. VW-MRI is useful in assessing lesion location, morphology, and severity. Additional information, such as vessel wall enhancement, which is useful in the differential diagnosis of atherosclerotic disease and vasculitis could be assessed by this special imaging technique. This review describes the VW-MRI technique and its clinical applications in arterial disease, venous disease, vasculitis, and leptomeningeal disease.
