Sonohysterography: do 3D reconstructed images provide additional value?

Objective: The purpose of this study was to retrospectively determine the value of adding 3D multiplanar sonography to 2D sonohysterography.

Materials And Methods: Between September 2003 and April 2005, 80 women (mean age, 43.5 years; range, 26-78 years) underwent sonohysterography with both conventional 2D sonohysterography and 3D multiplanar imaging (volume of data acquired and reconstructed in the transverse, sagittal, and coronal planes).

Levator ani abnormality 6 weeks after delivery persists at 6 months.

Objective: Assess postpartum changes in the levator ani muscle using magnetic resonance imaging and relate these changes to obstetric events and risk factors associated with pelvic floor dysfunction.

Study Design: A board-certified radiologist specializing in abdominal imaging evaluated 146 pelvic magnetic resonance studies from 57 primiparous women 6 weeks and 6 months after first obstetric delivery and 32 nulliparous women. A yes/no determination of muscle body and insertion integrity, muscle thinning, and measurement of muscle thickness in millimeters was made for each of 4 muscle sites: right and left puborectalis and right and left ileococcygeous.

Accuracy of segmentation of a commercial computer-aided detection system for mammography.

Purpose: To assess the accuracy of segmentation in a commercially available computer-aided detection (CAD) system.

Materials And Methods: Approval for this study was obtained from the authors' institutional review board. Informed consent was not required by the board for this review, as data were stripped of patient identifiers.
