Title: Real Time Contrast-enhanced Ultrasonography of Hepatic Tumors
Abstract: Objective: To assess the real time contrast-enhanced ultrasound (RTCEUS) at diagnosing hepatic tumors. Methods: Forty five patients (24 men, 21 women) with 63 tumors,which were confirmed by pathological findings,were examined by RTCEUS at low MI (0.05 0.08) after intravenous injection of SonoVue.The results were recorded and compared with that from baseline ultrasound. Results: The recall ratio of baseline ultrasound and RTCEUS was 87.3% and 96.8% respectively. For the tumors whose maximum diameter were under 1.0 cm, the recall ratio of baseline ultrasound and RTCEUS was 58.3 % and 16.7% respectively. 52.4% (33/63 )tumors' edge was shown unclearly when observed through baseline ultrasound, while for the RTCEUS, only 6.3%(4/63)tumors' edge was not shown clearly. The sensitivity, specificity and accuracy of baseline ultrasound in diagnosing malignant tumor of liver was 51.4%,66.7% and 56.4%. As for RTCEUS, they were 95.3%,94.4% and 95.1%. The difference was statistically significant (P 0.05). Conclusion: RTCEUS can provide much information about the number, size and edge of hepatic tumors than baseline ultrasound can do. It is superior to baseline ultrasound in the identification of hepatic tumors.
