RESUMO

Objective:In order to improve diagnostic accuracy, we study the characteristics of two dimensional ultrasound and shear wave elastography in the diagnosis of false negative or false positive thyroid nodules by shear wave elastography.Method:One hundred and eighty-nine nodules in 189 consecutive patients who had been determined by surgical operation and pathology. Conventional ultrasound features and SWE elasticity imaging characteristics and properties of the final postoperative pathology were recorded. A comparative study between true and false results of quantitative SWE elasticity imaging, and the corresponding conventional ultrasound nodule characteristics were compared.Result:Postoperative pathology showed 189 nodules, 74(39.2%) were benign and 115(60.8%) were malignant. The sensitivity, specificity of conventional ultrasound in the diagnosis of thyroid nodules were 56.5% and 81.1% respectively, and those of SWE were 60.9% and 85.1%. The false positive rate of shear wave elastography in diagnosing benign nodules and the false negative rate of malignant nodules were 14.9% and 39.1%, respectively. The false negative rate was higher than the false positive rate. A vertical growth (P< 0.01) and smaller diameter of the masses were significantly associated with false SWE findings (P< 0.01).Conclusion:The SWE imaging has important significance for differentiating benign and malignant thyroid nodules, but false results are inevitable, which requires clinicians conjunction with other test results to prevent errors judgment when reviewing the SWE imaging.

RESUMO

At present Non-A and Non-B hepatitis disseminated from the intestine in the world is believed to have a better prognosis and has no chronicity. From 1980-1986, this hepatitis has occurred in the south of Xinjiang. It was sporadic (1980-1985) and there was an outbreak (1986). Our study indicated that the results from 500 cases followed up for two years were different from the literature reported. 1. Patients with hepatomegaly were 11.2% at 7th months, 12.8% at 19th months and 45.3% at 28th months. At the same time there were 3 cases of splenomegaly and spider in each of the 19th month and 28th month. 2. Liver function test showed that gamma-GTP, BSP and gamma-globulins rose in different degrees among the 3-7 month cases. Reexamined at 19th months, 3.6% cases of both ZTT and SGPT were high. General proteins of 8% patients dropped. In 42% of the patients the globulins rose and the album in dropped. 3. Biopsy of the liver after 28th months demonstrated that it was in agreement with the pathologic changes found in chronic lobule hepatitis of CPH under the light microscope and electron microscope.
