TRANSVAGINAl COlOR DOPPlER UlTRASOUND IN EVAlUATION OF OVARIAN MASSES
Mohamed Farag Mohamed;
Abstract
Ovarian tumors are common in women. Many efforts have been carried out to improve the accuracy of sonography in discriminating benign from malignant lesions. The introduction of color and pulsed Doppler ultrasonography into gynecological use inspired a lot of research work in this field for several years.
The aim of this work was to determine the diagnostic accuracy of color Doppler ultrasound in differentiating benign and malignant ovari n
'
lesions and to ompare such results with those found at histopathological
diagnosis.
,This study included 200 patients with ovarian lesions diagnosed
I
clinically or by ultrasonography. After clinical examination, TVS was done for all cases. In addition TAS was done for 16 cases with large pelviabdominal masses which were out of the limited field of view of the vaginal probe. After observing all gray scale features, color Doppler was superimposed on the gray scale image to assess the flow characteristics and measure the Doppler indices (PI and RI).
The most discriminating gray-scale and Doppler features for the different lesions were evaluated. Regarding ovarian masses, the most discriminating gray scale features were the presence of solid parts, the occurrence and thickness of septa, the pr sence of papillae and presence of intraperitoneal fluid. The most distinguishing Doppler features were the location and arrangement of vessels (central or peripheral) related to the mass.
