The differential diagnosis of hepatic metastasis by CT and MRI

Abstract

In addition to ultrasound (US) screening, the current diagnostic imaging techniques of liver lesions are computed tomography (CT) and magnetic resonance imaging (MRI), which are the most commonly used noninvasive techniques. With constantly updated technology, CT and MRI machines have developed into a multispiral CT (320 layers/circle scan) and high-field-strength MRI machines (3 T); the scanning speed, tissue contrast, and spatial resolution have been significantly improved, and so have the diagnostic sensitivity, specificity, and accuracy. It also plays an extremely important role in the metastatic liver cancer detection, differential diagnosis, treatment, and follow-up work [1–3].
