Diagnostic curettage has for many years been the method of choice to diagnose endometrial cancer in women with postmenopausal bleeding. In fact, approximately only 10% in this group of women will be diagnosed with endometrial cancer. This study used endometrial thickness as measured by endovaginal ultrasonography as an indicator of endometrial abnormality. The histopathologic diagnosis obtained at curettage is used as the gold standard. 74 women were included in this study. Endometrial cancer was not found with the endometrium= 5 mm thick. The mean endometrial thickness in those women with endometrial cancer was 13.72+/- 8.09 mm compared with 4.3 +/- 2.3 mm in those women with benign endometrium. If the cut off limit for endometrial cancer and hyperplasia was 5 mm, the sensitivity was 100% the specificity was 71.2%, the positive predictive value was 60%, the negative predictive value was 100% and the Kappa ratio was 0.6%. If this limit had been used in this study, 70% of the curettage procedures could have been avoided.

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

13 patients with the gallbladder cancer diagnosed by ultrasound in which 6 patients received CT scanner, these images compared with the operational results and pathological anatomy. The gallbladder cancer occurred most frequently in the elderly and had the poor prognosis. The ultrasound showed the unfair thickness of gallbladder wall (66.7%) rough tumor from the posterior wall to gallbladder

43 patients with the bladder tumor received the clinical examination have shown that the rate of male/female was 6/11, average ages of patients were 60. 93% of patients had blood urination and stimulation syndrome of bladder. The transvaginal or transrectal ultrasound found that this was a comfortable method with no complication, and its invasion was less than transurinarytract ultrasound. The sensitivity of method was 95.2%. The limitation of this method was to find incompletely the number of tumors in some cases.

100 patients with ovarian cancer which were indicated of surgery at Tu Du Hospital from the year 2002 to 2004. The ultrasound scan results were compared with the anatonic pathology showed that ultrasound scan was a useful method in diagnosis and screening test for ovarian cancer. Especially the sensitivity and specificity of Doppler ultrasound were approximately 80%. Doppler ultrasound was the best method for diagnosis combination with the results of CA 125 in predicting the healthy and acute level of ovarian cancer

All patients with ovarian tumors which were indicated for surgery at Tu Du Hospital were underwent ultrasound scan as a routine test. The ultrasound scan results were compared with the pathology results to evaluate the accuracy of ultrasound. There were 100 patients recruited for this study, in which 19 malignant tumors. According to Tokyo University classification, the sensitivity and specificity of ultrasound were 82.4% and 79%, respectively. According to the authors' classification, they were 82.8% and 88%. The sensitivity and specificity of Doppler ultrasound reached optimal value at RI < 0.5 and at PI < 1. Serious carcinoma and mucinous carcinoma had the highest prevalence (52.62%). Ultrasound could be used as a diagnostic and screening test for ovarian cancer

A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings.

We encountered a patient with a breast mass which had metastasized from gastric carcinoma representing as aninflammatory carcinoma on ultrasonography. We described the radiologic and clinical features, and review theliterature. The patient had advanced gastric carcinoma and breast ultrasonography demonstrated the presence ofvery ill-defined, infiltrating, and mixed echoic lesions indistinguishable from findings of primary inflammatorybreast carcinoma. Metastatic gastric adenocarcinoma was confirmed pathologically.
