Intracranial vasculopathy with MR vessel wall imaging: a case series.

Conventional luminal imaging, often the first line investigation, has helped physicians in diagnosing countless patients with cerebrovascular disease but regrettably, it offers little diagnostic clues in patients with challenging vasculopathy, which the latter often requires invasive histopathological diagnosis. In past decade, MR vessel wall imaging has quickly emerged as a non-invasive modality that greatly enhances radiologists' capability of differentiating underlying aetiology. Not only it minimizes surgical trauma to patients, but also provide timely and accurate diagnosis for physicians to offer prompt appropriate treatment and avoid devastating outcomes. Tuen Mun Hospital, the neuroscience centre serving more than 1.3 million population in New Territories, Hong Kong, has been the pioneer in optimizing this novel modality within the district. In this article, we hope to share few interesting cases in our centre on how we utilize its advantage in solving some challenging cases. We would also discuss some common imaging pitfalls and tips on interpretation.
