Synopsis

Keywords: Liver, Tumor

Motivation: Hepatic hyperintense lesions, has been shown to be difficult for differential diagnosis in clinical.

Goal(s): Multiple parameters MRI can potentially provide whole insights into hepatic lesion diagnosis.

Approach: 144 patients based on hepatic hyperintense lesions (HCA and WDHCC) with presurgical MRI to investigate the differential diagnosis.

Results: Results demonstrated that MRI signal model can provide more effective information for the differential diagnosis of hepatic hyperintense lesions especially for HCA and WDHCC.

Impact: Differentiating Hepatocellular adenomas (HCA) and well-differentiated hepatocellular carcinoma (WDHCC) via MRI signal-based model could offer a more comprehensive diagnostic approach than clinical factors-based model and combined MRI signal plus clinical factors-based model.
