Illustrated review of new imaging techniques in the diagnosis of abdominal wall hernias

Background: The assessment of abdominal wall hernias has long been a clinical skill that only occasionally required the supplementary radiological assistance of herniography. However, with the advent of cross-sectional imaging, a new range of diagnostic tools is now available to help the clinician in difficult cases. Methods: This review explores the ability of computed tomography and magnetic resonance imaging to demonstrate many of the hernias encountered in the anterior abdominal wall. Also discussed is the role of imaging techniques in the management of a variety of hernias. Results and conclusion: Cross-sectional imaging techniques are being employed with increasing frequency for the assessment of hernias. Although the anatomical detail can usually be delineated dearly, the accuracy of the various methods and their place in the clinical management of hernias has yet to be fully determined.
