CT of abdominal cavity with contrast: preparation, procedure, result

CT of the abdominal cavity with contrast can be prescribed for a variety of diseases and indications, but it is important for the patient to know exactly how this procedure is carried out. In particular, you need to understand correctly how to prepare for it to achieve the most reliable result.

When should I see a doctor?

Quite often it happens that before a person is assigned CT of the abdominal cavity with contrast, he complains of pain in the abdomen or he is disturbed by any other symptoms emanating from the abdominal organs. At the same time, both the person himself and his attending physician can not simply determine the possible cause of this problem. The standard diagnostic procedure, which involves performing all sorts of tests, X-rays and ultrasound, often does not allow us to determine the cause of this ailment, and it is in this situation that CT of the abdominal cavity with contrast is appointed.

About 20 years ago, doctors did not even know what to do if the above methods did not bring the right result. However, today technologies provide much more modern and highly informative methods of diagnostics. One of them is a CT scan or, as it is called, a CT scan of the abdominal cavity with contrast.

In fact, CT is a significantly modernized version of standard radiography, which allows for much more accurate results and at the same time is much safer. But, one way or another, it is carried out today only if there is a doctor's appointment.

When is he appointed?

There are several indicators by which a CT scan of the abdominal cavity with contrast can be prescribed by the doctor. Preparation can be carried out if the following conditions are present:

  • Various diseases of the liver or biliary system, which includes anomalies of the structure of the ducts, tumors, cholelithiasis, cholangitis and many others.
  • All kinds of pancreatic diseases, such as negative tumors, cysts and inflammatory changes.
  • Pathology of the intestine and stomach. In this case, mainly in the diagnosis of tumors, doctors appoint CT of the abdominal cavity with contrast. Preparation for this procedure can begin already almost immediately after carrying out this diagnosis.
  • Damage to the abdominal cavity.
  • Diseases and injuries of the spleen.
  • Interstitial abscesses, as well as abscesses of various organs.

This is only the main list of reasons for which this procedure can be prescribed, therefore, in any case, it is best to get professional advice from your treating specialist.

What does it show?

If the correct preparation was carried out, and also a specialized diet for CT of the abdominal cavity was observed in contrast, then in the process of carrying out this procedure, a rather large amount of useful information can be obtained. The process itself involves creating a large number of pictures, each of which displays a separate tissue layer. All these images are characterized by the highest possible degree of detail and allow a complete picture of what processes are taking place in the patient's internal organs.

There are a number of factors that show CT of the abdominal cavity with contrast. The result of this procedure in the majority of cases allows to obtain data concerning the work of the following bodies:

  • The lymph nodes;
  • pancreas;
  • liver;
  • Vessels;
  • nerves;
  • spleen;
  • Bile ducts;
  • The gall bladder.

It is also important that in the course of this study you can see the structure of hollow organs, including the intestine and stomach, which is impossible for standard MRI technology. In addition, according to the pictures, the doctor can draw a conclusion about the condition of the lumbar vertebrae, since CT provides excellent visualization of bone tissue.

Benefits

The doctor should explain a lot of information if he sends the patient to a CT scan with contrast of the abdominal cavity: how to prepare, how to eat, how the procedure will be performed and much more. But in any case, carrying out such research guarantees obtaining the most reliable information regarding the state of any structures of the abdominal cavity, even if there are some serious pathological changes or hidden processes that spread simultaneously to several organs.

Thus, CT reviews of the abdominal cavity with contrast give positive feedback as patients for whom the procedure is as convenient and painless as possible, and doctors who receive all the necessary information necessary to diagnose and prescribe the patient's subsequent treatment.

What is it used for?

In the majority of cases, CT of the abdominal cavity is usually done with contrast. With the help of a contrast preparation, a significant improvement in the detailing of the images and the overall quality of the images is provided, which, accordingly, has a positive effect on the results of the performed diagnostics. At the same time, it is necessary to understand correctly that CT scan of the abdominal cavity is not always done with a contrast, since in some situations it is not necessary to perform its examination on specialized multispiral platforms (but it is better to discuss this with a doctor beforehand).

The only case in which the use of contrasting is required without fail is the suspicion that the patient has any pathological diseases. CT of the abdominal organs with contrast here is carried out regardless of the type of tomograph that belongs to, because the standard study is in any case less accurate than contrast.

By itself, the contrast is characterized by the ability to gradually accumulate in tumor tissues, so that in the pictures the foci of development of tumor cells become much more noticeable. Due to this, the doctor receives comprehensive information about the boundaries of primary metastases and tumors, and also about their number, which greatly helps in planning treatment. Experts know why CT scan of the abdominal cavity with contrast, which shows the picture and how to treat it. Ultimately, the doctor has the opportunity to prescribe treatment in full accordance with a certain stage of the process, which already allows you to count on the success of its conduct.

How to prepare?

In any case, the patient should prepare for computed tomography independently, and the procedure should be approached as responsibly as possible, if in the end you want to achieve really accurate results.

The main goal of the training is to achieve the ultimate visualization of the images taken. If it is a question of carrying out a survey of the abdominal cavity, the quality of visualization can be seriously affected by the presence of a crowded, swollen bowel. It is for this reason that during the preparation process, it will be necessary to take care of the normal functioning of the digestive tract at the time of the study. To achieve this, 2-3 days before the CT of the abdominal cavity (without contrast or with contrast), special procedures are carried out, the main purpose of which is to prevent increased gas production or the occurrence of constipation.

During this period, the patient should be extremely responsible approach to the issue of nutrition. In particular, it is necessary to completely eliminate from the diet products that cause flatulence or stool retention. If a person is accustomed to making his own menu in accordance with the rules of healthy eating, he will not have any difficulties in order to correct the diet, and he will easily transfer any diets so that the computer abdominal imaging shows the most accurate result.

Preparations

It is also worth noting that during this period it is recommended to take special drugs-sorbents, and in most cases doctors prescribe standard activated charcoal, which should be drunk twice a day for two tablets. Also, if desired, you can use other drugs. In particular, as a sorbent and simultaneously a fairly good remedy for flatulence, the drug "Smecta" can be used.

In the event that a person has any really serious problems with the digestive tract and its separate functions, the preparation plan for the CT scan of the abdominal cavity should be previously agreed with the attending physician. For various indications, you may need to take laxatives, antispasmodics or even an enema.

To come on research it is necessary exclusively on an empty stomach, and after the previous reception of food should pass about 6-8 hours. For this reason, the most convenient is the diagnosis in the morning, while breakfast has not yet been accepted. Also, it is not recommended to drink any liquid two hours before the procedure, since it can provoke a brisk peristalsis, which prevents normal diagnosis.

Is it possible to carry out the procedure for children?

CT of the abdominal cavity is performed today for both adults and children, since the radiation load received by the patient during the scanning process is extremely low and can not endanger the health of the child. In the majority of cases, modern clinics take children from 14 years to perform this procedure, but in some centers this age restriction is reduced to 10, and somewhere even up to 7 years. Young children can also undergo computed tomography if necessary, but the study of such patients is carried out in specialized centers or in sufficiently large pediatric clinics.

Here, the whole point is that in the process of conducting a study, patients should remain completely immobile, and this is quite difficult to achieve from very young children. In this regard, their examination is carried out in conditions of special medical sleep with the use of safe drugs and under the close supervision of a professional anesthesiologist.

What does the conclusion show?

Based on the results of the procedure, the doctor draws up an opinion, which contains all the information about the state of human health that was obtained during the course of this event. The doctor describes not only sick, but also healthy organs, including their basic features of anatomy, dimensions and other information. Conclusion is given to the patient together with fully printed images.

At the same time, one must correctly understand that the CT results are not a diagnosis, they are only a description of the main changes in internal organs. It should be noted that the pictures help a lot in the diagnosis. Quite often, this procedure completes the diagnosis, since it allows the attending physician to obtain all the necessary information to determine the exact disease and the purpose of the appropriate treatment.

Price

By itself, computed tomography differs by an order of magnitude less than MRT, but it is still not the cheapest procedure. You also need to understand that the cost directly depends on which clinic you are applying to.

Basically, the price is determined depending on several factors. First of all, the apparatus on which the research is conducted plays a role here. In other words, the standard procedure will cost less when compared to diagnostics on spiral and multi-helix devices. Also, the price rises if the study uses contrast. In addition, the location of a clinic, the qualifications of physicians participating in the study, and many other factors also play a role.

In most cases, the cost of computed tomography is directly proportional to its quality, but in fact, this rule is not always true. A large number of modern centers offer retirees, students, as well as a whole host of other people a lot of discounts. Also, all sorts of actions are often held, at the time of which the passage of the diagnosis is also available at a reduced price to all comers.
