The Roles of Contrast-Enhanced Harmonic Imaging in Treating Hepatocellular Carcinoma

  • Masatoshi Kudo


As described in Chap. 4, ultrasonic blood flow imaging has five roles in the evaluation of hepatocellular carcinoma (HCC). They are (1) lesion detection or screening, (2) characterization (differential diagnosis), (3) evaluation of malignant grade, (4) staging, and (5) evaluation of treatment response. The last role is the most important because, although harmonic imaging contributes greatly to differential diagnosis of hepatic tumors, there are limitations on the ability to characterize tumors. HCC accounts for the largest number of hepatic tumors in Japan. Even if HCC is diagnosed by harmonic imaging, most cases also require further examination by computed tomography (CT) and angiography. Specifically, if most cases of hepatic tumors are HCC and borderline lesions accompanying HCC, then CT, magnetic resonance imaging (MRI), and angiography cannot be avoided to ensure more precise characterization and evaluation of malignant grade.
