OBJECTIVE: The purpose of this study was to assess the intraobserver and interobserver agreement for identifying different endometrial vascular patterns using power Doppler sonography in women with postmenopausal bleeding and a thickened endometrium. METHODS: Digitally stored sonographic images from a random sample of 65 patients with postmenopausal bleeding and a thick endometrium (>5 mm) on B-mode sonography and evaluated by transvaginal power Doppler sonography for assessment of endometrial blood flow mapping were evaluated by 5 different examiners with different levels of expertise in Doppler sonography. Intraobserver and interobserver agreement according to the level of experience were assessed by calculating the kappa index. RESULTS: Intraobserver agreement was good or very good for all experienced examiners (kappa = 0.78-0.96) and moderate (kappa = 0.52) for the inexperienced examiner. Interobserver agreement was moderate among all experienced examiners (kappa = 0.45-0.80). The inexperienced examiner showed fair or moderate interobserver agreement (kappa = 0.32-0.45). CONCLUSIONS: Our results indicate that endometrial blood flow mapping using transvaginal power Doppler sonography is acceptably reproducible. More experience was associated with better intraobserver and interobserver agreement. |
