摘要: Objective : To evaluate the accuracy of three-dimensional (3-D) ultrasound (US) follicular volume measurements. Design Prospective clinical study. Setting A tertiary referral center for assisted reproduction. Patients Twenty-five patients undergoing ovarian stimulation IVF-ET using long protocol GnRH agonist. Intervention Transvaginal two-dimensional (2-D) and 3-D scan performed immediately before US-directed follicle aspiration. Main Outcome Measures The fluid aspirated was compared with corresponding measured by US conventional 2-D measurement calculated formula π/6 (D 1 x D 2 3 ). Limits agreement 95% confidence intervals were systematic bias between methods analyzed. Results limits aspirate determined +0.96 to -0.43 mL measurements +3.47 -2.42 Conclusions true follicles, within clinically useful range cycles, is more accurately a system than techniques.
