X-rays
Various types of X-Ray and radiological procedures are often used to diagnose Crohn’s disease, or to assess the condition of a Crohn’s patient’s disease.
Each radiological examination carries with it certain risk factors, such as exposure to radiation.
Below is a chart showing the average radiation level introduced into the body with each procedure commonly used in Crohn’s patients. Amounts vary due to the use of several kinds of radioactive contrast.
