Ultrasound is also limited by its inability to image through air (lungs, bowel loops) or bone.

In this form of lymphoma, fistula formation (an abnormal communication between the tumor and adjacent bowel loops) is common.

At laparotomy she was noted to have thickened bowel loops and a thickened dilated colon.

Specifically, the features of endoexoenteric lymphoma are an irregular collection of barium due to central ulceration, and displacement of adjacent bowel loops.

Twelve hours later, abdominal girth and the radiographic diameter of the distal transverse colon had decreased to 95 and 10 cm respectively, and there was a reduction in dilatation of small bowel loops.

A report suggested CT enteroclysis to be superior to conventional enteroclysis in evaluation of symptomatic Crohn's disease, especially for the detection of fistula, abscess, skip lesions, lymphadenopathy, and conglomeration of small bowel loops.

Tumors that infiltrate the bladder require more radical surgery where part or all of the bladder is removed (a cystectomy) and the urinary stream is diverted into an isolated bowel loop (called an ileal conduit or Urostomy).

In such patients, a bowel loop is often used to create either a "neo-bladder" or an "ileal conduit" which act as a place for the storage of urine before it is evacuated from the body either via the urethra or a urostomy respectively.

Radiographic signs of NEC include dilated bowel loops, paucity of gas, a "fixed loop" (unaltered gas-filled loop of bowel), pneumatosis intestinalis, portal venous gas, and pneumoperitoneum (extraluminal or "free air" outside the bowel within the abdomen).
