The objective of this study was to evaluate whether intratumoral blood flow as assessed by transvaginal color Doppler ultrasonography (TVCD) correlates with some tumor features in cervical cancer. Clinical, sonographic, and histologic data on 49 women (mean age: 50.3 years, range: 25–85 years) diagnosed as having a carcinoma from the uterine cervix were reviewed. Intratumoral blood flow was assessed by TVCD in all cases. Subjective impression of the amount of flow (scanty, moderate, or abundant) as well as the lowest resistance index (RI) and highest peak systolic velocity (PSV, cm/s) were used for analysis. These data were correlated with some tumoral features such as histologic type, histologic grade, tumor volume, and tumor stage. Intratumoral blood flow was found in all cases. Abundant blood flow was found more frequently in squamous carcinoma, moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.0001). Significantly lower RI was found in moderately or poorly differentiated tumors and advanced stage tumors (P < 0.01) and significantly higher PSV was found in moderately or poorly differentiated tumors, tumors with larger volume, and advanced stage tumors (P < 0.01). No correlation was found between RI and PSV and histologic type. Our data indicate that intratumoral blood flow as assessed by TVCD correlates well with some tumor features in cervical cancer.

Abstract Objective The aim of this study was to assess ovarian blood flow characteristics by applying transabdominal color Doppler ultrasonography during the course of the estrous cycle in gilts. Materials and methods Estrus and ovulation were synchronized in 15 pubertal gilts. During their consecutive spontaneous estrous cycle the gilts were sonographically scanned daily and ovarian blood flow was determined by imaging perfused areas of the ovarian hilus and the ovarian tissue. Recorded video clips were then analyzed for the parameters perfused area (Amix), blood flow velocity (vmix) as well as resistance (RIvmix) and pulsatility index (PIvmix) using the software PixelFlux®. Results All blood flow parameters showed an estrous cycle dependent course, with Amix and vmix being highest in diestrus, followed by proestrus, while RIvmix and PIvmix patterns were inversely proportional. Conclusion and clinical relevance Transabdominal color Doppler ultrasonography proved feasible to study ovarian perfusion characteristics in pubertal gilts. The ovarian blood flow was dependent on the stage of estrous cycle and highest in diestrus. The results of this study encourage the use of color Doppler ultrasonography to also investigate reasons of ovary-caused infertility including corpus luteum insufficiency or seasonal effects on ovary function.
