This review compares brain hemodynamics imaging techniques like PET, SPECT, and MRI. It highlights the pros and cons of each method to help clinicians choose the best option for specific patient needs.

Area of Science:

  • Neuroimaging
  • Medical Physics
  • Radiology

Background:

  • Brain hemodynamics evaluation is crucial for diagnosing various neurological conditions.
  • Multiple imaging modalities exist, each offering insights into cerebral blood flow and volume.
  • Despite shared goals, these techniques possess distinct advantages and limitations.

Purpose of the Study:

  • To provide a comparative overview of leading brain hemodynamics imaging techniques.
  • To establish a consensus among specialists regarding the strengths and weaknesses of each modality.
  • To aid clinicians in selecting appropriate imaging methods for specific clinical scenarios.

Main Methods:

  • Comparative review of established brain hemodynamics imaging techniques.
  • Consensus-based evaluation by specialists in the field.
