CT perfusion imaging is vital for acute ischemic stroke treatment up to 24 hours. Understanding subacute CT perfusion findings is crucial for timely, effective patient care and avoiding treatment complications.

Area of Science:

  • Neuroradiology
  • Emergency Medicine
  • Stroke Imaging

Background:

  • Current guidelines recommend perfusion imaging up to 24 hours post-ischemic stroke.
  • Patients with salvageable brain tissue benefit from reperfusion therapies.
  • CT perfusion is increasingly utilized in the subacute stroke phase.

Purpose of the Study:

  • To explain the fundamental concepts of "code-stroke" CT perfusion.
  • To detail typical findings and common pitfalls in subacute ischemic stroke CT perfusion.
  • To provide a practical guide for interpreting urgent CT perfusion studies.

Main Methods:

  • Review of CT perfusion imaging in the subacute phase of ischemic stroke.
  • Discussion of "code-stroke" protocols and interpretation challenges.
Keywords:

  • Highlighting differences between hyper-acute and subacute CT perfusion findings.

    • Main Results:

    • Subacute CT perfusion findings differ from hyper-acute findings.
    • Accurate interpretation is critical due to time-sensitive treatment decisions.
    • Misinterpretation can lead to exclusion from beneficial treatments or unnecessary, dangerous interventions.

    Conclusions:

    • Radiologists must be proficient in interpreting urgent CT perfusion studies.
    • Correctly identifying salvageable tissue is essential for guiding reperfusion therapy.
    • Accurate CT perfusion interpretation directly impacts patient outcomes in acute ischemic stroke.
