The sonographic findings in 200 patients who underwent concurrent transabdominal and transvaginal pelvic ultrasound were reviewed. The sonographic techniques were compared for image quality, completeness of anatomic detail depicted, and unique diagnostic information. Transvaginal image quality was better in 79%-87% of scans; transabdominal image quality was better in 3%-5% of scans; images of both techniques were equally good in 10%-18% of scans. The techniques provided equivalent diagnostic information in 60%-84% of cases. Transvaginal sonography was particularly helpful when exclusion of ectopic pregnancy was the clinical concern. Individual organs and fine structures were better seen transvaginally, but the regional survey offered by the transabdominal full-bladder approach remains necessary to provide anatomic orientation, particularly when the patient has not been studied previously.
回顾了200例同时接受经腹和经阴道盆腔超声检查患者的超声检查结果。比较了两种超声检查技术在图像质量、所显示解剖细节的完整性以及独特诊断信息方面的差异。经阴道超声检查在79%-87%的扫描中图像质量更佳；经腹超声检查在3%-5%的扫描中图像质量更佳；两种技术的图像在10%-18%的扫描中同样良好。在60%-84%的病例中，两种技术提供了等效的诊断信息。当临床关注排除异位妊娠时，经阴道超声检查特别有用。经阴道可以更好地观察单个器官和精细结构，但经腹膀胱充盈法提供的区域检查对于提供解剖定位仍然是必要的，特别是当患者之前未接受过检查时。
