From the Research
CT abdomen is not typically recommended as the first-line imaging test for diagnosing a hernia. Physical examination by a healthcare provider is usually sufficient for diagnosing most hernias, particularly those that are visible or palpable. When imaging is needed, ultrasound is generally the preferred initial test as it is non-invasive, does not use radiation, and can effectively visualize hernias while allowing dynamic assessment during maneuvers like coughing or straining.
Key Points to Consider
- CT scans are usually reserved for complex cases, suspected complications (such as strangulation or bowel obstruction), planning for complex hernia repairs, or when other conditions need to be ruled out 1.
- CT exposes patients to radiation and is more costly than ultrasound, making it less suitable as a routine diagnostic tool for uncomplicated hernias.
- MRI might be considered as an alternative in certain situations, particularly for pelvic floor or sports hernias.
- If you suspect you have a hernia, the best approach is to consult with a healthcare provider who can perform a physical examination and determine if any imaging is necessary based on your specific situation.
Imaging Modalities
- Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment 1.
- MRI is beneficial when there is reasonable concern that a patient's symptoms could be attributable to a hernia or a musculoskeletal source 1.
- Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination 1.
