No specific data are available relative to the sensitivity, specificity, or accuracy of upper GI with small bowel follow-through in the diagnosis of abdominal wall hernias. MRI Abdomen Without and With IV Contrast There is no relevant literature regarding the use of MRI abdomen in the evaluation of abdominal wall hernia. However, the modality would be able to depict the anatomy, and theoretically, visualize a hernia. The specific performance attributes are unknown. MRI Abdomen Without IV Contrast There is no relevant literature regarding the use of MRI abdomen in the evaluation of abdominal wall hernia.

MRI Pelvis There is no relevant literature regarding the use of MRI pelvis in the evaluation of abdominal wall hernia. However, the modality would be able to depict the anatomy, and theoretically, visualize a hernia. The specific performance attributes are unknown. Radiography Abdomen and Pelvis There is no relevant literature regarding the use of radiography abdomen and pelvis (KUB) in the evaluation of abdominal wall hernia. However, there may be utility if there is concern for bowel obstruction. US Abdomen US has long been used in the evaluation of the palpable abdominal masses. The ability to differentiate the abdominal wall from intraabdominal processes and distinguish the abdominal wall layers is well established. Use of high- frequency transducers and dynamic maneuvers frequently demonstrate the fascial defect and herniated abdominal structures with their characteristic US features [24]. In a case series with surgical confirmation of presence of Spigelian hernia, US demonstrated a sensitivity of 90% and a PPV of 100% [9]. Dynamic US demonstrated a high sensitivity, specificity, PPV, and NPV of 98%, 88%, 91%, and 97%, respectively, in the diagnosis of incisional hernias in a prospective study of 181 patients.
