VASARI MRI feature set

A.Prof Frank Gaillard et al.

The VASARI (Visually AcceSAble Rembrandt Images) MRI feature set is a system designed to enable consistent description of gliomas using a set of defined visual features and controlled vocabulary. It is the result of work by The Cancer Imaging Archive (TCIA) who publish relevant guides to use, and additional resources 1,2. The system has been fairly widely adopted and is often used in articles that include tumour morphology description. At the time of editing (August 2016), this system has following features being taken in account. 

Features

The system comprises 25 features each denoted by a name, number and description. A detailed description of each with examples is available as a PDF from TCIA 2. The features are:  

  • tumour location (f1)
  • side of lesion centre (f2)
  • eloquent brain (f3)
  • enhancement quality (f4)
  • proportion enhancing (f5)
  • proportion nCET (f6)
  • proportion necrosis (f7)
  • cysts (f8)
  • multifocal or multicentric (f9)
  • T1/FLAIR ratio (f10)
  • thickness of enhancing margin (f11)
  • definition of the enhancing margin (f12)
  • definition of the non-enhancing margin (f13)
  • proportion of oedema (f14)
  • haemorrhage (f16)
  • diffusion characteristics (f17)
  • pial invasion (f18)
  • ependymal extension (f19)
  • cortical involvement (f20)
  • deep white matter invasion (f21)
  • nCET crosses midline (f22)
  • CET crosses midline (f23)
  • satellites (f24)
  • calvarial remodelling (f25)
