Brain tumour protocol (MRI)

MRI protocol for brain tumour assessment is a group of MRI sequences put together to best approach CNS tumours in general.

Note: This article is intended to outline some general principles of protocol design. The specifics will vary depending on MRI hardware and software, radiologist's and referrer's preference, institutional protocols, patient factors (e.g. allergy) and time constraints. 


A good protocol for this purpose involves at least:

  • T1 weighted
    • plane: axial and sagittal (or volumetric 3D)
    • sequence: fast-spin echo (T1 FSE) or gradient (T1 MPRAGE)
    • purpose: anatomical overview, which includes the soft tissues below the base of skull
  • T2 weighted
    • plane: axial
    • sequence: T2 FSE
    • purpose: evaluation of basal cisterns, ventricular system and subdural spaces, evaluation of vasogenic oedema, and good visualisation of flow-voids in vessels
    • plane: axial
    • sequence: FLAIR
    • purpose: assessment of white-matter tumour involvement and related vasogenic oedema
  • diffusion-weighted imaging (DWI)
    • plane: axial
    • sequence: DWI: B=0, B=1000 and ADC 
    • purpose: evaluation of the tumour cellularity 
  • postcontrast sequences
  • susceptibility weighted imaging (SWI)

When assessing gliomas it is relevant to include advanced MRI sequences, such as:

  • perfusion
  • spectroscopy
    • sequence: single or multivoxel spectroscopy
    • purpose: metabolic peaks characterisation
