What is better for internal organ diagnosis – MRI of the bowel or colonoscopy?
Sometimes there are situations when we have to choose between the two procedures, though differing from each other, but serving roughly the same purpose. For example, you may choice that the better – MRI of the bowel or colonoscopy. Because the second is quite painful to humans, because many are looking for a way to replace it. But it is important to understand these procedures and their specific advantages, disadvantages and differences to thoroughly understand this issue.
Colonoscopy bowel is a medical diagnostic procedure in which a doctor examines the colon of the patient from the inside using an endoscope. To diagnose lesions of the colon tissue, in particular, ulcers and polyps; take tissue samples for biopsy and to remove small polyps. This procedure is a standard method of investigation of the colon. Accordingly, there are a only one indication is the need to implement the diagnosis of diseases of the colon.
When compared with magnetic resonance imaging, colonoscopy has the following advantages:
- more affordable price;
- effectiveness in identifying problems somehow affecting the colon;
- the ability to simultaneously carry out the biopsy and a range of therapies.
This diagnostic method and several disadvantages. These include:
- The need for mandatory consent to the procedure. If the patient resists, it is impossible to diagnose. This is very important, for example, in the implementation of the survey children, which can very wildly for him to respond.
- Painful procedure.
- The inability of the survey to any other organs besides the colon.
There are also a number of contraindications, which include:
- megacolon toxic type;
- puncture of the large intestine.
There are a number of relative contraindications, e.g., pregnancy, recent myocardial infarction, and several others. In this case, the decision remains for the attending physician.
Usually the main negative factor for patients is strong, painful factor. Also many people very uncomfortable the need for careful preparation for the procedure, because it requires well emptying stomach. Another inconvenient fact that for some time after the implementation of the diagnostics needs to stay in a medical institution. All of these factors individually is usually not critical, but together form a rather negative attitude to the procedure and make you wonder – is it possible to do an MRI of the bowel is a colonoscopy?
Magnetic resonance imaging is an approach to scanning the body when used with a sufficiently strong radio waves and magnetic fields, which allow to obtain a sufficiently clear picture of the internal organs. The procedure uses a special scanner.
Often combined with contrast-enhanced MRI is used, which allows a much more objective examination of the condition of the intestines.
This procedure applies in the following situations:
- the need to identify the source of painful sensations in the abdomen;
- the need to study the lymph nodes of the abdomen;
- the presence of hemorrhage and congenital anomalies;
- diagnosis of kidneys, liver;
- diagnostic examination of the pancreas or spleen;
- the presence of cancers or benign tumors;
- the need to identify the blood supply to the abdominal organs.
By using this procedure are very easy to identify the tumor from the normal tissue, so in such situations, MRI is almost indispensable.
The positive properties of the procedure are the following:
- patient comfort during;
- the absence of pain and, as a consequence, no necessity of anesthesia;
- a qualitative study of the small intestine, and all organs of the abdomen by choice;
- great view of the middle part of the intestine.
The computer procedure can be carried out not for all people. There are certain contraindications, which include:
- the presence of pacemakers and other medical devices;
- the presence of activated electric way implants, insulin pumps and others;
- the presence of remaining in the body of metal fragments and similar things that can make the procedure dangerous and, in addition, biased;
- pregnancy in the first trimester (in the rest of the trimester the procedure can be performed);
- the presence of dental prostheses;
- the presence of cerebral palsy or too young age.
Undesirable conduct procedures when the presence of wires, heart valves and other similar things, but then make the decision on the procedure should the attending physician based on the specific situation and the potential risks associated with it.
The procedure is uninformative:
- if peristalsis is too active;
- in emergency situations;
- with very small changes in the intestinal mucosa;
- with a small amount of sites of inflammation.
What to prefer?
If you have a choice, MRI or colonoscopy, should first rely on the opinion of a competent doctor who can objectively assess what is best for you. Most people tend to abandon a colonoscopy, because it brings them discomfort, but the principle of selection is more complicated.
If strongly to simplify the situation, we can come to these conclusions:
- A colonoscopy will definitely be better MRI if suspect on the emergence and development of diseases affecting the colon.
- MRI will be relatively better, if you want to examine other internal organs.
But this is only a rough estimate of what is best in what situations. Often there is a question, colonoscopy or MRI of the bowel, not even worth it, because we need both of this approach. For example, if a person can suddenly be diagnosed with a tumor of the colon, then a colonoscopy will help to more accurately identify the cancer and biopsy, while MRI can detect, has not carried out if the germination of this mass in lymph nodes and neighbouring parts of the body.
Choosing which is best – MRI of the bowel or colonoscopy, it is important to remember that both of these procedures are very important in the implementation of diagnostics of internal organs. Both methods have advantages and disadvantages, both features characteristic of indications and contraindications. So no need to choose. You need to trust the doctor, which will be based not on the subjective characteristics of these procedures, and how they fit in your specific case. Because all cases are unique and the act is necessarily situational.
