Why radiologists do not take direct Xray photographs of intestine? (1) Intestines are affected by direct exposure to X-rays (2) X-rays can not cross intestine (3) X-rays are not able to capture clear picture (4) Even short exposure of X-rays causes cancer in intestine

1 Answer

Answer :

(3) X-rays are not able to capture clear picture Explanation: As the intestine is a soft tissue structure, it is not usually seen on a plain X-ray. By using barium to coat the inner lining of this area the Radiologist can see the bowel clearly on the X-ray screen, and can watch the way it functions during this study. A small lubricated plastic tube will be inserted through your nostril or mouth and down into your stomach by the Doctor or Nurse.
