Analysis of clinical effect of high-intensity focused ultrasound on liver cancer

Figure 1 A 42-year-old male with hepatocellular carcinoma. A: MRI T₁-weighted images before HIFU treatment showed that liver tumor of right-posterior lobe was 115 mm × 100 mm × 66 mm; B: MRI enhanced imaging before HIFU revealed that enhancement of mass in liver right-posterior lobe was higher than that of surrounding normal liver tissues; C: MRI T₁-weighted imaging 11 mo after HIFU revealed that liver tumor of right-posterior lobe obviously decreased in size (50 mm × 55 mm × 60 mm); D, E: MRI enhanced imaging (cross section and coronal section) 11 mo after HIFU revealed that liver tumor had shrunk obviously, blood supply of tumor was eliminated, the tumor therapeutic region had coagulation necrosis.
