Usually enemas are available after imaging, and in some cases, imaging is even an enema.
Imaging is mainly done by injecting substances containing elements with a high atomic number, such as iodine, into the body, and medical diagnosis is made through imaging tests based on the distribution and changes in the location of the contrast agent in the body. There are many types of them, such as upper gastrointestinal imaging, colonography, angiography, and tubography. Generally, intestinal enemas do not affect the results.
Bowel enemas are usually injections of fluids into the bowel, such as warm saline, paraffin oil, glycerin solution, etc., for the treatment of constipation or bowel cleansing. Its injection lumen is usually not the same as the injection site of the contrast agent, so it has little effect on the contrast results. But the contrast of the colon tract is examined by barium enema, the way itself is a kind of enema.
