Radiomics and Machine Learning in Medical Imaging

Remarkable advances in imaging modalities now make it possible to discern small hepatocellular carcinomas (HCCs). Unfortunately, most patients with HCC have underlying cirrhosis and the tumors frequently recur in other portions of the liver. 1 Ikeda K Saitoh S Tsubota A et al.

However, transcatheter arterial embolization is ineffective in some cases of poorly vascularized HCC. 5 Kuroda C Sakurai M Monden M et al.

Residual cancer tissue may be present in small tumor nodules surrounding the main tumor, in regions isolated by septa, or along the periphery of the lesion. 6 Shiina S Tagawa K Unuma T et al.
