Abstract

Diastasis of the rectus abdominis muscles (rectus diastasis, RD) is common, particularly in postpartum women. Although imaging is not always mandatory for assessment, several cross-sectional imaging techniques, in particular ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) can depict the abdominal wall in exquisite detail. They permit simultaneous assessment of the degree and craniocaudal extent of RD, evaluation for co-existent hernia and subjective judgement of muscle quality. Increasingly, dynamic imaging techniques show both static anatomy and muscle movement and function. In this review, we highlight the imaging findings of RD, associated hernia, and potential mimics.

Keywords: Abdominal hernia; Diastasis, muscle; Medical Imaging; Rectus Abdominis.
