2025年3月25日 · Transient ischemic attacks (TIAs) describe a transient episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. In …

With the development of brain imaging, particularly diffusion weighted imaging-magnetic resonance imaging (DWI-MRI), the diagnosis of TIA changed from time-based definition to a …

Just how effective is an MRI at detecting a transient ischemic attack or TIA? Well, when compared to a CT scan, an MRI “is more sensitive when evaluating someone for a TIA or stroke,” says …

1997年7月1日 · Magnetic Resonance Imaging. Magnetic resonance imaging (MRI) of the head is used less often than CT for initial evaluation of patients with TIA because it is a more …

2024年11月8日 · Studies have shown that TIA patients with evidence of acute infarction on MRI had a 3 to 18 times higher risk of stroke compared to those without acute infarction. Therefore, …
