Conventional Radiography
Disadvantages of Conventional Radiography
Diagnostic accuracy is limited in many situations. Other imaging tests may have advantages, such as providing better detail or being safer or faster. Intestinal contrast agents such as barium and gastrografin (an iodine-based oral contrast agent), if used, have disadvantages (see Disadvantages of CT ), and IV Fluoroscopy may involve high doses of radiation (see Risks of Medical Radiation ).
