Objective To explore the diagnostic value of ultrasonography in acute abdomen of women.Methods 269 women with acute abdomen were examined with ultrasonography,the results were compared with clinical and pathological data.Results Of 269 cases,78 cases of ectopic pregnancy,26 cases of ovarian cyst torsion,44 cases of endometriosis("chocolate" cyst),33 cases of ruptured corpus luteum cyst,69 cases of acute pelvic inflammatory mass,6 cases of ovarian cyst rupture,2 cases of pedical of subserous myoma,5 cases of ovarian teratomas,2 cases of ovarian fibromas and 4 cases of red degeneration of uterine myoma were diagnosed by sonography.In comparsion with pathological results,the accorded rates of ultrasonography were 83.3%,84.6%,81.8%,72.7%,82.6%,66.7%,50%,60%,50% and 50% respectively.Conclusion As its convenience and rapid,ultrasonography plays an important role for the diagnosis of acute abdomen in gynecology.

Objective To evaluate the value of color Doppler flow image(CDFI)in diagnosis of acute renal allograft rejection in early stage,by comparative study on CDFI,single photon emission computer tomography(SPECT)and biopsy.Methods A total of 65 patients were included in this study,including acute rejection in 26 cases,chronic rejection in 12 cases,acute tubular necrosis in 7 cases,toxic reaction of cyclosporine a in 2 cases and normal in 18 cases.They were all subjected to CDFI and biopsy,and 44 were detected by SPECT.We reviewed two-dimension gray scale picture,spectrogram,perfusion index(PI),resistant index(RI),the ratio of blood flowing velocity of systole period and diastole period(S/D) as correlated to the findings of SPECT and biopsy.Results The RI values were 0.77?0.05 and 0.72?0.07 in acute rejection group and chronic rejection group respectively,which were obviously higher than those in normal group(0.57?0.07).Conclusion CDFI is a fast,accurate and non-invasive technique in evaluating renal transplant rejection early.
