    Diseases of the colon are very common among the entire pathology of the gastrointestinal tract. However, there are several effective methods to detect them, the main of which is the endoscopic examination of the intestine, or magnetic resonance method. Many patients wonder which is better – an MRI of the bowel or colonoscopy? No clear-cut answer is very difficult, as each of these research methods has its advantages and disadvantages, which will be discussed further.

    Similar research methods should always be done after consultation with your doctor to identify current indications and contraindications.

    • Internal intestinal bleeding of any causation.
    • The need for biopsy of mucosa of the colon with subsequent histological examination or the necessity of a small surgical intervention to stop bleeding from the vessel, removal of polyp etc.

    Endoscopy is used for examination of the colon more often than MRI, which is associated with the possibility of obtaining more accurate information.

    The advantages and disadvantages of the methods: which is better?

    So which method is better – colonoscopy or MRI of the bowel? Both methods have both disadvantages and advantages to effectively use them in different situations.

    Each method has its own indications and contraindications that determine their use.

    The advantages and negative characteristics of MRI studies

    MRI of the gut has the following advantages in comparison with analogues:

    • Allows you to detail the presence and degree of damage of the bowel wall and parietal structures.
    • Copes well with the diagnosis of neoplastic lesions and fistula, connecting the lumen of the body with other bodies.
    • The lack of negative impact on the patient’s body through the use of a safe magnetic field. The only exception is patients with pacemakers and metal implants.

    • Despite significant advantages, the method has significant limitations:
    • Ill-suited for the detection of inflammatory and ulcerous lesions of the colon wall.
    • Not detect cancer in the early stages of its development, which affected only the mucous membrane.
    • The high cost of research.

    The purpose of MRI studies performed after a medical examination by a doctor and determine whether the testimony of the patient.

    Colonoscopy: pros and cons

    The main advantages of this survey:

    • Visual inspection of the mucosa, allowing to detect even small pathological processes, such as ulcers, inflammatory infiltrates and polyps.
    • Unlike MRI, it is possible to identify the inflammatory process in the mucosa.
    • Option of receiving the piece of mucous membrane for further morphological examination and accurate diagnosis.
    • You can conduct small surgical operations, to cauterize sores and bleeding blood vessels, to remove polyps and other lesions in the lumen of the intestine.

    The disadvantages of this method:

    • Psychological discomfort from the procedure and the possibility of side effects from anesthesia.
    • Failure to comply with the engineering study may damage the wall of the colon with the development of complications or the appearance of bleeding.
    • Exacerbation of inflammatory processes in the body wall due to mechanical irritation or drift of the infectious agent from the outside.
    • There is a decline in blood pressure.
    • The need for careful preparation for colonoscopy.

    Before the procedure, the patient must receive information about preparing for the procedure your doctor.

    What is better MRI study of the large intestine or colonoscopy? The result shows that endoscopy is best suited for the detection of pathological processes in the early stages of their development, and if necessary, biopsy, and minor surgical interventions. MRI of the bowel allows to identify space-occupying lesions in the intestinal wall, as well as its metastases.
