Of these, 6/12 patients had renal abscesses, of whom 6/6 (100%) of the patients were identified on both US and contrast-enhanced CT. One patient had multiple perirenal abscesses, and another patient had a gas-forming perinephric abscess that were both missed by US but seen on CT. CT Abdomen and Pelvis Without and With IV Contrast There are no data to support the use of any added value of a CT abdomen and pelvis without IV contrast immediately before acquisition of a contrast-enhanced CT in the diagnosis of sepsis. Sepsis CT abdomen and pelvis with IV contrast but may be useful in specific clinical situations such as urosepsis from suspected obstructing renal calculi or ureteral calculi. FDG-PET/CT Skull Base to Mid-Thigh There are no data to support the use of FDG-PET/CT as an initial diagnostic imaging study in the diagnosis of sepsis. Fluoroscopy Contrast Enema There are no data to support the use of fluoroscopy contrast enema as an initial diagnostic imaging study in the diagnosis of sepsis. Fluoroscopy Upper GI Series with Small Bowel Follow-Through There are no data to support the use of fluoroscopy upper gastrointestinal (GI) series with small bowel follow- through as an initial diagnostic imaging study in the diagnosis of sepsis. MRI Abdomen and Pelvis Without and With IV Contrast There are no data to support the use of MRI abdomen and pelvis without and with IV contrast as an initial diagnostic imaging study in the diagnosis of sepsis. The majority of patients with sepsis are too unstable to undergo a relatively long imaging procedure, especially with the availability of alternate imaging modalities that are shorter and easier to obtain. However, in certain situations, such as targeting a specific source of clinically suspected infection, MRI has been shown to be useful. Given that perianal sepsis occurs in up to 10% of neutropenic patients, Ashkar et al [14] performed a retrospective review of neutropenic patients from hematologic malignancy who were given the diagnosis of perianal sepsis.
