RESUMEN
Background: The purpose of the study is to evaluate the role of uterine artery blood flow parameter measured by uterine artery two-dimensional (2D) power coloured doppler (PCD) ultrasound in predicting fertility outcomes in women undergoing ART treatment.Methods: It is prospective observational study. Total of 60 patients were included of receiving infertility treatment in the age group20-40 years. 20 patients were selected for timed intercourse , 20 patients were selected for intrauterine insemination , 20 patients were selected for invitro fertilization. Transvaginalsonography will be done on the day of trigger by BHCG , UA PSV were measured, and endometrial blood flow will be assessed. Predictivity of pregnancy rate will be looked after by 3 ways: BHCG values , UPT, Gestational sac on USG.Results: In TI/IUI/IVF cycles the Doppler parameter PSV of uterine artery (23.08+/-3.39 vs 20.37-/+5.43) in pregnant vs non-pregnant group did not differ significantly. The mean PSV of UA shows no significant difference women who were became pregnant during treatment and the women who were not became pregnant.Conclusions: With help of Doppler parameter imaging of women undergoing infertility it was found that UA PSV is non-significant to decide the prediction of pregnancy outcome.
RESUMEN
Objective: To retrospectively characterize and analyze the thyroid ultrasound images of thyroid cancer patients, to classify thyroid nodules according to thyroid imaging reporting and data system (TI-RADS), and to evaluate the diagnostic value of TI-RADS. Methods:Clinical data of 160 thyroid cancer patients with 235 nodules from September 2008 to August 2011 were retro-spectively analyzed. All patients underwent conventional color Doppler ultrasonography to evaluate the size, number, shape, boundary, and extent of lesions and blood distribution of the nodules. All nodules were analyzed according to TI-RADS classification and scored to evaluate the diagnostic value of TI-RADS. Results:Among 176 malignant nodules, 144 (81.8%) had lesions showing a mass of irreg-ular boundary with no envelope and halo, 152 (86.4%) were inhomogeneous hypoechoic or slightly hypoechoic, or 144 (81.8%) exhibit-ed microcalcification. TI-RADS scores of 4 or 5 and 2 or 3 were obtained in 160 (90.91%) and 16 (9.09%) of the malignant nodules, re-spectively. Conclusion:Thyroid ultrasound sonogram of ill-defined, irregular shape, hypoechoic or slightly hypoechoic mass, microcal-cification within the mass, and rich blood flow is an important index for the diagnosis of thyroid cancer. Thyroid nodules with a TI-RADS score 4 or 5 have higher possibility for cancer. Therefore, TI-RADS has a significant diagnostic value for thyroid cancer be-fore operation.
