22. Overview: RECIST vs. RECIST 1.1

“MRI has excellent contrast, spatial and temporal resolution; however, there are many image acquisition variables involved in MRI, which greatly impact image quality, lesion conspicuity and measurement. The availability of MRI is variable globally. Chest MRI not recommended”

• Measurements are possible on isotropic reconstructions and non-axial MRI planes:
  • sagittal
  • coronal
  • (oblique)

Also here the key point is consistency. Always measure in the same plane.
