High-resolution diffusion-weighted imaging of lesions in transient ischemic attack

Takeaway

  • High-resolution diffusion-weighted imaging (hrDWI) may provide more detailed information on patient status and prognosis following transient ischemic attack (TIA).

Why this matters

  • Diagnostic criteria for TIA have evolved from time-limited symptomology to characteristic tissue changes as imaging technology has advanced.

  • More sensitive tissue-level characterization of TIA outcomes using hrDWI may facilitate intervention better suited to patients’ clinical status and prognosis.
