MR Perfusion: Techniques used for Intracranial Tumour Assessment.

The article examines the magnetic resonance (MR) perfusion techniques and its potential benefits in the context of the diagnosis, staging, therapeutic response and prognosis in patients who have intracranial tumours. The two major MR methods that have been developed and applied to the assessment of brain perfusion are Dynamic Susceptibility Contrast (DSC) imaging and Arterial Spin Labelling (ASL). It cites that the implementation of individual patient quantitation when utilizing the DSC method may result to improve clinical utility by minimisation of normal variation and increase in pathological specificity. It suggests further study in the form of well controlled, large scale clinical studies are needed to assure the pathology-specific imaging efficacy of DSC and ASL techniques.
