Fast magnetic resonance imaging (MRI) now allows for cerebral haemodynamics imaging. This review covers perfusion imaging techniques, their limitations, and clinical uses, especially for stroke and brain tumors.

Area of Science:

  • Radiology and Medical Imaging
  • Neuroscience
  • Biomedical Engineering

Background:

  • Advancements in fast magnetic resonance imaging (MRI) have enabled detailed visualization of cerebral haemodynamics.
  • Understanding blood flow dynamics in the brain is crucial for diagnosing and managing neurological conditions.

Purpose of the Study:

  • To describe the theory and common MRI techniques for perfusion imaging.
  • To discuss the limitations of current perfusion imaging methods.
  • To explore the clinical applications of perfusion imaging, particularly in stroke and brain tumor cases.

Main Methods:

  • Overview of the most commonly used MRI technique for perfusion imaging.
  • Theoretical explanation of the principles underlying perfusion imaging.
