Visibly enhancing lesions are not always malignant, and some benign lesions can be distinctly enhancing in the same way. If there is a hypodense shadow on the liver, the edge of the lesion in the arterial phase is nodularly intensified. In the venous phase and delayed phase, the enhancement is enlarged, and the delayed phase lesion is largely filled with an isointense or hyperdense shadow. The enhancement pattern of this lesion is obvious enhancement, but according to the characteristics of its enhancement pattern, the liver lesion is considered to be a hepatic hemangioma rather than a malignant lesion, and hepatic hemangioma is a benign liver tumor. In addition, FNH on the liver is also significantly enhanced, but this lesion is not malignant either. Therefore, lesions that are significantly enhanced are not necessarily malignant.
