Preparation for MRI
Preparation for MRI
Preparation is obligatory for the following examinations:
- MRI of the abdominal cavity,
- MRI of the lesser pelvis,
- MRI of the whole body
How to prepare for MRI of the abdominal cavity, MRI of the lesser pelvis, MRI of the whole body
Preparation for MRI of the abdominal cavity, MRI of the lesser pelvis, or MRI of the whole body should start 24 hours before the examination:
- The day before the diagnostic examination, exclude fibre-containing foods, such as fresh fruits and vegetables.
- Do not eat foods that increase gas generation in the intestinal tract. These include cabbage, bread, legumes, dairy products.
- In the evening before the examination, patients prone to constipation are recommended to do a cleansing enema or take a laxative to prepare the intestinal tract. For patients that are not prone to constipation, just a timely defecation will be sufficient. Remember that to perform MRI of the lesser pelvis, the rectum should be free of faecal masses and gas, therefore, the second defecation is recommended immediately prior to the examination.
- The last meal should be not later than 8 hours before the examination.
- Drinking still water is allowed 3 to 6 hours before the examination.
- Urinate 2 hours before the examination
- Arrive for the examination in a fasted state
- 30-40 minutes before the examination, you need to take a medicinal product that prevents the increased intestinal motility (Buscopan, No-Spa, Drotaverine 120 mg), or 1 mL of Glucagon intramuscularly or intravenously before the examination.
