Answer

Nuclear scanning

Nuclear imaging diagnostic studies have little use in the initial evaluation of patients with suspected peritonitis or intra-abdominal sepsis. They are most frequently used in the evaluation of fever of unknown origin or in patients with persistent fever despite adequate antibiotic treatment and negative computed tomography scan findings.

Contrast studies

Conventional contrast studies (ie, Gastrografin swallow, upper gastrointestinal tract study with follow-through, colorectal contrast enema, fistulogram, contrast studies of drains and stents) are reserved for specific indications in the setting of suspected peritonitis or peritoneal abscess.
