During diagnosis, the doctor gets a three dimensional picture where you can see the slightest pathological changes that are invisible by other methods, such as ultrasound.

    The organs examined with CT of the abdomen, identify the organs of the gastrointestinal tract:

    Indications for imaging can be:

    • Acute injuries of the abdomen – CT scan shows the nature of the injury, its extent, the massive bleeding from the damaged organ.

    • Suspected pathological formation in the abdominal cavity. This study is most reliable in cases of suspected cancer, it allows you to identify tumor at the earliest stages of development, indicates the degree of metastasis, the boundaries of education, degree of involvement of adjacent tissues and organs.
    • Monitoring earlier treatment.
    • A sharp decline in the weight of the patient and a suspicion of a mechanical jaundice.
    • Inflammatory processes of the gastrointestinal tract.
    • Dystrophic process.
    • Foreign body.
    • Abnormal development of the digestive system.
    • Diseases of the liver.

    • Instability in the mental state of the patient. Procedure even mentally healthy person is able to cause excitement due to the confined space and loud noise in the scanning process.
    • The presence of metallic foreign bodies in the human body (plates, braces, implants).

    Relative:

    • Breast-feeding. Within days after the examination, it is not recommended to feed the baby breast milk, as it is able to accumulate radiation.
    • Children up to age 14 years. It is preferable to use alternative methods of examination.

    • Diseases of the circulatory system.
    • Cardiovascular pathology.
