Abstract
|
|
|
It has been reported that there are some differances between malignant and benign tumor in the wave form of the intratumoral or surface arterial blood flow. Transvaginal Doppler ultrasound with color flow imaging was used in 24 women with ovarian
tumor
before explorative laparotomy.
The impedence of wave forms were analysed using values of pulsatility index (PI). Transvaginal sonographic (TVS) scoring system and CA 125 were also checked before operation. The sensitivity of PI was 100%, compared with those of TVS scoring
system
(75%) and CA 125 (63%) even though the specificity of PI(81.3%) was less than those of TVS scoring system (87.5%) and CA125(93.8%). But in the early stage of cancer the sensitivity of PI (100%) is quite higher than those of TVS scoring system
(60%)
and
CA 125(40%). Based on the results transvanginal Doppler color flow imaging may be a useful clinical tool in the differential diagnosis of malignant ovarian tumor.
