  • The CT-study
  • The use of virtual colonoscopy bowel
  • Diseases of the digestive tract with lesions of the colon are common. In this regard, much attention is paid to the development and implementation of effective diagnostic and therapeutic procedures. One of the modern methods for detecting diseases of the colon, a virtual colonoscopy of the intestine, showing a high level of diagnosing diseases at early stages of their development. This procedure assigns the attending physician when the patient has suspicion of a lesion of the colon. The basis of this method, multislice computed tomography, which allows to obtain a high quality image of the colon.

    Virtual colonoscopy of the bowel is also referred to as CT-colonoscopy or CT colonoscopy.

    The main advantages of the virtual colonoscopy:

    • No risk of perforation of the colon wall and the development of internal intestinal bleeding.
    • How to use the method in patients with diseases of the rectal region (fissures, hemorrhoids, etc.) that extends to the use of this procedure.
    • High-quality images of the bowel with the possibility of volumetric reconstruction.
    • A small list of contraindications to the appointment of the study.

    Unlike magnetic resonance imaging, computed tomography allowed patients with installed pacemakers, prosthetic and other metal products.

    Reviews patients strictly positive due to the rapid conduction and absence of any invasive manipulation compared with colonoscopy.

    The purpose of the survey

    Determine to whom to appoint CT scan of the intestine should only doctor after the physical examination of the patient and other diagnostic procedures. In this case, you can get a good diagnostic effect subject to the financial component.

    The CT or virtual colonoscopy is shown in the following situations:

    • Suspected neoplastic processes in the intestine (cancer of any morphological type).
    • Chronic inflammatory or ulcerative diseases with affection of the organs of the digestive system.
    • Frequent constipation, stool softener or increased flatulence.
    • If you suspect internal bleeding inside the colon.
    • In old age as a screening method for early detection of neoplastic tumors and other pathological processes.

    The only contraindication to the use of this method of research is pregnancy, in connection with the negative impact of x-ray radiation on the developing fetus.

    Preparation for the procedure

    To obtain a meaningful result it is necessary to observe recommendations on how should be the preparation for virtual colonoscopy. More information on this matter can be obtained from the attending physician.

    Compliance with the diet

    The first and most important step in the preparation for the virtual colonoscopy – the observance of a certain diet to reduce gas in the colon and hasten her evacuation. Patients are encouraged to abandon bakery products, products of wheat and other coarse grain, reduce the intake of vegetables and fruits in any form (boiled, fresh, etc.).

    In addition, certain requirements to the drinking regime: it is necessary to abandon the strong tea, coffee, fizzy and carbonated drinks, and milk.

    Colon cleanse

    The optimal results of the tomography can be obtained only at pre-cleaning the colon of its contents. To do this, use two approaches – setting regular enemas or receiving medication to speed up stomach emptying.

    One day before the survey allowed to drink only plain water or weak vegetable or chicken broth. Besides you can’t take anything for food.

    The CT-study

    Before examining the patient dressed in a special shirt that does not have any metal elements and buttons, as well as ask to remove or take out of the pockets of metal objects and jewelry. Otherwise, it can lead to the appearance of the photographs of the various artifacts that hinder the process of interpreting the information received.

    It is very important to prepare for the study, following diet and cleanse the gastrointestinal tract.

    The patient is placed on a special table solid on the back. After that, through the anus inserted a small probe used for insertion into intestinal air or contrast agent required for smoothing and a better display in the pictures. The study itself takes place for 5-20 minutes, depending on the required number of images and complexity of the diagnosis of the underlying disease. On average, one treatment get several hundred or thousand images, that allows not only to analyze each of them, but also to reconstruct the 3D image of the colon. This ends the procedure.
