T2 Mapping (relaxometry)


Quibim has developed this suite to automatically obtain the T2 mapping of tumors and depict changes and abnormalities with AI segmentation. The analysis of T2 mapping provides imaging biomarkers for the assessment and monitoring of solid tumors, such as prostate cancer, rectal cancer and liver cancer, among others.
