Answer

CT scanning is readily available in most hospitals and should be considered the imaging study of choice, as it defines the extent of the disease more specifically than plain films or ultrasound. CT scanning can reveal smaller amounts of soft-tissue gas than plain radiography and can demonstrate fluid collections that track along the deep fascial planes. [62, 63]

Findings include soft-tissue and fascial thickening, fat stranding, and soft-tissue gas collections. CT scan often identifies the underlying cause of the infection (eg, perirectal abscess). The findings may assist in surgical planning.
