The authors of this retrospective study aimed to evaluate the diagnostic performance of a radiomics model in order to classify hepatic cyst, hemangioma, and metastasis in patients who have been diagnosed with colorectal cancer (CRC) from portal-phase abdominopelvic CT images. The study found that, although inferior to radiologists, the radiomics model was able to achieve substantial diagnostic performance when differentiating hepatic lesions from portal-phase CT images of CRC patients.

Key points

  • Albeit inferior to the radiologists, the radiomics model could differentiate cyst, hemangioma, and metastasis with substantial diagnostic performance using portal-phase CT images of colorectal cancer patients.
  • The radiomics model demonstrated limitations especially in classifying hemangiomas and subcentimeter liver lesions.
