The May 2021 issue of the Neuroimaging Clinics of North America concerns neurovascular imaging and is entitled Evidence-Based Vascular Neuroimaging. Edited by Drs. Malhotra and Gandhi, this issue contains 10 chapters with contributions from 25 authors.
What makes this publication valuable is that it addresses issues and topics that neuroradiologists face multiple times each day, such as detecting and dealing with unruptured intracranial aneurysms, imaging of vasospasm, extracranial vascular disease (with emphasis on plaque imaging), subarachnoid hemorrhage without a known cause, ischemic stroke with common parameters on MRI and CT, spontaneous intracerebral hemorrhage, AVMs, vessel wall imaging in intracranial vascular disease, and the use of CT algorithms in acute ischemic stroke.
While the chapter on unruptured intracranial aneurysms (UIAs) reviews some important points such as those related to eventual rupture/growth or key factors in describing aneurysms, the lack of any images to illustrate the authors’ points is a disappointment. There are innumerable features the authors describe but apparently decided not to show; such illustrations would have resulted in a greater impact of this material. On the other hand, the authors summarize the literature (evidence-based data) on UIAs. It is clear by the volume of studies in the literature and criteria used that many unanswered questions on management and aneurysm evaluation remain.
Documenting vasospasm and diagnosing delayed cerebral ischemia (DCI) are briefly discussed and important points re: Doppler US, DSA, CTA, and pCT are made. Better depiction of vasospasm should have been made, using larger formatted DSA imaging combined with properly placed labels.
The segment on extracranial vascular disease discusses and illustrates the important observations regarding arterial narrowing and plaque formation. The authors of this chapter do not illustrate important …
