When examining the gastrointestinal tract and suspecting a serious illness, a computer (CT) or magnetic resonance imaging (MRI) scan is performed. Only these two types of examinations can give a full picture of violations in the digestive tract. With more common diseases, ulcers, bowel obstruction, polyps, CT is usually prescribed, which within 15 minutes will reveal all the disorders, including internal bleeding. MRI is prescribed by an MRI scan centres in Noida in more complex cases, with suspected neoplasms in the gastrointestinal tract or when other examination options do not give an exact answer in determining the disease.
Pay attention to your intestines with the following symptoms:
- Black feces or blood feces (see a doctor immediately)
- Often recurring pain in the abdomen or anus
- Prolonged feeling of nausea
- Prolonged constipation
- Frequent diarrhea
MRI is prescribed to the patient to obtain the final picture of the disease, as well as:
- With suspected tumors
- If the patient is pregnant
This is explained by the fact that in MRI, unlike CT, the patient is not exposed to aggressive radiation during the procedure. Therefore, CT is strictly contraindicated for pregnant women, and MRI is allowed from the third month. CT can also not be done more than once a year. CT is prescribed for suspected internal bleeding, and when there is a suspicion of a violation of the complete integrity of the intestines and stomach. Also, when there is a suspicion of acute bowel obstruction. With CT, the patient is exposed to radiation; with this, there are limitations in its use.
With CT, doctors can accurately determine the state of the gastrointestinal tissue and the violation of their integrity, determines wall defects, perforation of the stomach and intestines, and the state of sphincters.
MRI gives a picture of changes in cell metabolism and reveals significant pathologies, including malignant and benign tumors, cholelithiasis, and inflammatory processes in the pancreas.
It is not difficult to prepare these procedures:
- Forget about vegetables, fruits, grain bread and other products containing coarse fiber per day
- 8 hours before the examination, stop any meal
- An hour before the procedure, take 5-6 tablets of activated carbon, if there are no contraindications.
WHAT TO CHOOSE: CT OR MRI?
When choosing between CT and MRI, it is necessary to take into account the features of each type of examination and recommendations of MRI scan centers in east Delhi. When making a decision, the following factors should be considered:
The clinical picture. If you suspect diseases such as an ulcer, polyp, other disorders in the structure of the intestinal wall or obstruction, they often turn to computed tomography. This examination allows you to detect internal bleeding, which helps to save the patient's life. Due to the fact that the study takes no more than 10-15 minutes, the diagnosis of an injury to the gastrointestinal tract and the appointment of the necessary treatment is fast enough.
Suspicion of oncology. MRI of the gastrointestinal tract allows you to get an accurate diagnosis regarding cancer. Finding a tumor, especially in the pancreas, is quite difficult, especially in acute inflammation. This method provides an accurate diagnosis of such pathology and makes it possible to prescribe effective therapy.
