The purpose of this study was to evaluate the usefulness a contrast-enhanced contrast-specific ultrasonographic technique with low mechanical index for characterization focal liver lesions.Contrast-specific ultrasonography used assess 144 patients 147 lesions: 87 primary carcinomas, 27 hemangiomas, 16 nodular hyperplasias, 5 hepatic abscesses, 3 inflammatory pseudotumors liver, and 9 metastases. A sulfur hexafluoride gas-based contrast agent 0.08 0.11.On ultrasonography, typical hemodynamic pattern carcinoma whole-lesion enhancement or mosaic in arterial phase an defect late (sensitivity, 92.0%; specificity, 86.7%). most common hemangioma that appeared periphery first progressively filled into lesion center 96.3%; 97.5%). hyperplasia whole enhanced early rapidly centrifugal radiating configuration isoechoic hyperechoic until 87.6%; 94.5%). central scar detected 31.3% cases phase. specific abscess honeycomblike all phases 80.0%; 100%). No pseudotumor liver.Contrast-enhanced real-time is promising approach noninvasive lesions can be useful as first-line imaging clinically when detectable on ultrasonography.
