PURPOSE: The purpose of this study was to investigate the value of UltraFast Doppler ultrasonography (US) for evaluating hepatic vessels in liver recipients. METHODS: Thirty-nine liver Doppler US sessions were conducted in 20 liver recipients. Each session consisted of UltraFast and conventional liver Doppler US in a random order. We compared the velocities and phasicities of the hepatic vessels, duration of each Doppler study, occurrence of technical failures, and differences in clinical decisions. RESULTS: The velocities and resistive index values of hepatic vessels showed a strong positive correlation between the two Doppler studies (mean R=0.806; range, 0.710 to 0.924). The phasicities of the hepatic vessels were the same in both Doppler US exams. With respect to the duration of the Doppler US exam, there was no significant difference between the UltraFast (251+/-99 seconds) and conventional (231+/-117 seconds) Doppler studies (P=0.306). In five poor breath-holders, in whom the duration of conventional Doppler US was longer, UltraFast Doppler US (272+/-157 seconds) required a shorter time than conventional Doppler US (381+/-133 seconds; P=0.005). There was no difference between the two techniques with respect to technical failures and clinical decisions. CONCLUSION: UltraFast Doppler US is clinically equivalent to conventional Doppler US with advantages for poor breath-holders during the post-liver transplantation work-up.

Cholangiolocellular carcinoma is a rare lesion, intermediate in type between hepatocellular and cholangio-cellular carcinoma. The radiologic findings of cholangiolocellular carcinomas have not been reported. We describe the ultrasound, CT, MR, and angiographic findings of a case of cholangiolocellular carcinoma not associated with liver cirrhosis.

PURPOSE: To determine the effects of power and coagulation time on lesion size of ex-vivo bovine liver using microwaves. MATERIALS AND METHODS: Six bovine livers were divided into two groups(first group: 30W output, secondgroup: 60W output) and microwave coagulation was performed for 30, 60, and 120 sec. thermal injury site was thenobserved by means of sonography, and the maximal transverse diameter of the echo-change portion after microwave coagulation was measured. On the section of specimen, maximal transverse diameters of the thermal injury site weremeasured by gross inspection and compared with the result of sonographic measurement. RESULTS: Maximal transversediameters of hyperechoic lesions of the first group, as seen on sonography were 8.3 mm, 12.2mm, and 15.6mm, andthe maximal transverse diameters of thermal injury sites on gross specimens were 9.1mm, 12.0mm, and 15.1mm,respectively. Maximal transverse diameters of hyperechoic lesions of the second group, as seen on sonography, were12.1 mm, 17.4 mm, and 21.2 mm and maximal transverse diameters of thermal injury sites on gross specimens were13.2 mm, 16.0 mm, and 20.0 mm, respectively. Statistically maximal transverse diameters of hyperechoic lesions, asseen on sonography, correlated closely with the gross findings of maximal transverse diameters of thermal injurysites(p<0.05). CONCLUSION: Maximal transverse diameters of thermal injury sites were significantly increased asthe output of the microwave coagulator and the duration of coagulation time increased(p<0.05).

From May 1997 to May 1998, we conducted punctuation and aspiration of 30 cases of liver tumors under the guidance of ultrasound in order to diagnose by cytology. The result showed that, accurate diagnosis was 95% better than that given by the examination done with ultrasound (83.5%) and FP (52.5% positive). Punctuation and aspiration of liver tumors under the guidance of ultrasound is a simple method, easily to apply with high accuracy and allows quick and early diagnosis at the admission of the patient

Studying on 50 patients with fatty liver, aged > 16 years old, treated at Bach Mai Hospital from Dec 2002 – Jun 2003. All patients had laboratory tests such as: blood - lactose, liver enzymes, HBsAg, lipemia, liver ultrasound. Lipemia disorder occurred in 74% of these patients, and mainly increased triglyceride; the level of lipemia components was not different by severe level of fatty liver by ultrasound. In patients with fatty liver caused by alcohol, the level of HDL-C (1.55  0.52 mmol/l vs. 1.21  0.31 mmol/l) was higher than those without alcohol

142 patients underwent diagnostic ultrasonography. Out of these, 100 patients have liver tumor and 42 have liver abscess. The prevalence is higher in male than in female and higher in 20-60 years of old than in other age groups. Liver tumor and abscess are more likely to be seen in right lobe than in left lobe with size of 5-10cm (55.7%). For liver abscess, sound reduction is more common (25.03%), while for liver tumor, sound combination and mixes are common types.
