The purpose of this study was to compare the accuracy of first-trimester pelvic sonography done by physicians after a 2-week emergency ultrasound elective to similarly numbered examinations done by physicians longitudinally over several years of residency training. ⋯ The accuracy of pelvic sonography for first-trimester pregnancy was comparable between physicians who participated in a 2-week emergency ultrasound elective and those who performed the same number of examinations over a longer period during residency training.
