    Computerized tomography detected hypodense lesions in 14 of 83 transient ischemic attack patients. Lesions were exclusively in the middle cerebral artery region, indicating its significance in these events.

    Area of Science:

    • Neurology
    • Radiology
    • Neuroimaging

    Context:

    • Transient ischemic attack (TIA) is a critical warning sign for stroke.
    • Accurate diagnosis and localization of TIA-related brain changes are essential for timely intervention.
    • Computerized tomography (CT) is a widely used neuroimaging modality for evaluating acute neurological events.

    Purpose:

    • To investigate the utility of computerized tomography in identifying brain lesions in patients presenting with transient ischemic attack.
    • To correlate CT findings with the clinical presentation and affected brain regions in TIA patients.

    Summary:

    • This study analyzed CT scans of 83 patients with transient ischemic attack (TIA).
    • Hypodense lesions, indicative of ischemic changes, were identified in 14 patients, exclusively within the middle cerebral artery (MCA) territory.

  • Cerebral atrophy was noted in 31 patients, predominantly of minimal degree.
  • No lesions were found in the basilar region despite 12 patients presenting with symptoms in this area.

    • Impact:

    • Highlights the sensitivity of CT in detecting acute ischemic changes in the MCA territory during TIA.
    • Suggests that CT may be less sensitive for detecting acute changes in the basilar region in TIA patients.
    • Provides valuable data for understanding the neuroimaging correlates of TIA and guiding diagnostic protocols.
