Can an ultrasound detect swelling in intestine?

It definitely can: It definitely can, although more detailed information and comprehensive overall picture can be obtained from ct or mri. "the potential value of transabdominal sonography (ultrasound) in the diagnosis of bowel diseases is often not sufficiently appreciated and is even underestimated." read more: http://www.Ajronline.Org/doi/full/10.2214/ajr.174.1.1740107.

See answer: Ultrasound is severely limited by bowel gas – if one is evaluating intestines (large or small bowel) , generally ct is a diagnostic consideration or possibly a barium examination (either upper or lower GI depending on the area of interest). Lastly, for repeated evaluation of bowel, as in crohns disease or for concern related to radiation, MRI enterography may be an option in the correct clinical s.
