This article discusses the use of generative artificial intelligence (GAI) tools, like ChatGPT, in residency applications. It argues that GAI tools should not be prohibited as they can help level the playing field for applicants who may not have access to traditional resources. However, concerns about the authenticity and specificity of content generated by GAI are acknowledged, and the article suggests ways for educators to evaluate and mitigate the impact of GAI in the application process.

Arterial spin labeling (ASL) is a magnetic resonance perfusion technique that allows for quantification of cerebral blood flow (CBF) without the use of contrast or radiation. Several applications of ASL have been described in diagnosis of strokes and stroke mimics, intracranial tumors, and other conditions. Various vascular anomalies exhibit specific CBF patterns that correlate with different signal intensities on ASL. In this case-based review, we demonstrate the utility of ASL in diagnosis and surveillance of vascular anomalies in the intracranial compartment. [ABSTRACT FROM AUTHOR]

Arterial spin labeling (ASL) is a noninvasive neuroimaging technique that allows for quantifying cerebral blood flow without intravenous contrast. Various neurovascular disorders and tumors have cerebral blood flow alterations. Identifying these perfusion changes through ASL can aid in the diagnosis, especially in entities with normal structural imaging. In addition, complications of tumor treatment and tumor progression can also be monitored using ASL. In this case-based review, we demonstrate the clinical applications of ASL in diagnosing and monitoring brain tumors and treatment complications. [ABSTRACT FROM AUTHOR]
