Two- and three-dimensional transvaginal ultrasound with power Doppler angiography and gel infusion sonography for diagnosis of endometrial malignancy.

摘要: Objectives To evaluate the diagnostic efficiency of two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasonography, power Doppler angiography (PDA) gel infusion sonography (GIS) at offline analysis for recognition malignant endometrium compared with real-time evaluation during scanning, to determine optimal image parameters 3D analysis. Methods One hundred sixty-nine consecutive women postmenopausal bleeding endometrial thickness ≥ 5 mm underwent systematic pattern on 2D imaging, videoclips volumes were later analyzed offline. Histopathological findings hysteroscopy or hysterectomy used as reference standard. The different techniques diagnosis malignancy was calculated compared. parameters, volume vascular indices assessed. Optimal transformed by logistic regression into a risk cancer (REC) score, including scores body mass index, thickness morphology gray-scale PDA GIS. Results Offline equivalent, but had lower performance scanning. Their not markedly improved addition GIS, their comparable that 2D-GIS in examinations good quality. On regression, from REC-score system highest efficiency. area under curve 3D-GIS (0.89) inclusion calculations. Conclusion Real-time scanning is most efficient, useful prediction when quality can be obtained. may use REC-scoring systems, without need calculation volume. imaging modality appears 2D-GIS.
