ABSTRACT
Objective To analyze the misdiagnosis reasons in renal tumors with contrast-enhanced ultrasound (CEUS) and to improve cognition on CEUS. Methods Two-hundred and eighty-five cases were compared with pathology, the images in 22 cases misdiagnosed on CEUS were reviewed retrospectively and the reasons were analyzed. Results The diagnosis accuracy and misdiagnosis rate of CEUS were 92. 28 % (263/285) and 7. 72%(22/285), respectively. In these 22 cases, 9 cases misdiagnosed as renal cell carcinoma (RCC) were conformed by pathology as renal angiomyolipoma(RAMD), showed 5 cases "fast wash-in and fast wash-out", 4 cases "fast wash-in and slowly wash-out". Seven cases were conformed as RCC, in which 5 were misdiagnosed as RAML, showed 4 cases "fast wash-in and slowly wash-out", 1 cases "simultaneously wash-in and simultaneously wash-out", and 2 were misdiagnosed as renal cyst with no enhancement founded. Four cases misdiagnosed as hematoma were conformed as pyelo-carcinoma, with no enhancement founded in renal pelvis. The remaining 2 cases misdiagnosed as inflammatory pseudotumor were conformed as RCC, showed "fast wash-in and slowly wash-out". Conclusions With the high diagnosis accuracy,CEUS is an important method in diagnosis of renal tumors. Analyzing the misdiagnosed reasons may improve the cognition on CEUS and decrease the misdiagnosis.
ABSTRACT
Objective To evaluate the value of diagnosis and treatment of fallopian tube patency by using hysterosalpingocontrast sonography (HyCoSy) with SonoVue and transvaginal ultrasound for infertile women. Methods Two hundred and twenty-two infertile women were examined by HyCoSy-SonoVue to observe flowing condition in womb and fallopian tube,the results were compared with hydrotubation, X-ray hysterosalingography(HSG) and laparoscopy(hysteroscopy). Results In the 222 cases,73 cases were both side of fallopian tube patency, 72 cases were single fallopian tube patency, 13 cases were single partial obstruction,60 cases were both side of fallopian tube pinning,4 cases were both partial obstruction. There was a significant difference on pregnancy rates between the HyCoSy-SonoVue and hydrotubation (P 0.05). There was no difference on diagnostic rates of fallopian tube pateney between the HyCoSy-SonoVue and laparoscopy (hysteroscopy)(P>0. 05) ,the diagnostic rate of H yCoSy-SonoVue was higher than that of HSG. Conclusions The HyCoSy-SonoVue method is safety and it would be an effective diagnosis in the evaluation of fallopian tube pathology for infertile women.
