Single\u2010vessel pattern and rim\u2010like vessel pattern were considered to be characteristic of endometrial polyps and submucosal fibroids, respectively. Suspected diagnoses of the lesions according to vascular Doppler characteristics were compared with the final diagnosis following histopathological examination.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Included in the final analysis were 49 patients with histological confirmation of the type of endometrial lesion: 32 with endometrial polyps and 17 with submucosal fibroids. Power Doppler signals were observed in 47 of these; they were not observed in two patients with endometrial polyps. Of the 32 with endometrial polyps, 26 (81.3%) endometrial polyps showed a single\u2010vessel pattern, three (9.4%) showed a multiple\u2010vessel pattern and one (3.1%) showed a scattered\u2010vessel pattern. Of the 17 with submucosal fibroids, 12 (70.6%) showed a rim\u2010like vessel pattern, three (17.6%) showed a multiple\u2010vessel pattern and two (11.8%) showed a single\u2010vessel pattern. Single\u2010vessel pattern was associated with two false\u2010positive cases, but there were no false\u2010positive cases for rim\u2010like vessel pattern. The sensitivity, specificity and positive and negative predictive values for single\u2010vessel pattern in diagnosing endometrial polyps were 81.2%, 88.2%, 92.9% and 71.4% and for rim\u2010like pattern in diagnosing submucosal fibroids they were 70.6%, 100%, 100% and 86.5%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Power Doppler blood flow mapping is a valuable tool in the diagnosis of focal endometrial pathology and is useful in distinguishing submucosal fibroids and endometrial polyps.
