CT (computed tomography) of the gallbladder
In our time, with a poor environment and poor quality food, diseases of the gallbladder and biliary tract diseases such as cholecystitis, are among the leading number of patients in abdominal surgery (operation on the abdomen). Now we easily can diagnose pathology of these bodies by various methods. One of them is the CT scan.
What is computed tomography?
This method of beam diagnostics is recognized as highly accurate and safe. It is based on x-rays, and in fact is considered to be improved and modified x-ray machine has special computer systems that improve quality and automatically adjust the camera to get a readable, informative and clear shot. He takes pictures of cross sections of the body that gives the ability to check on the pathology of specific organs, including the gallbladder.
Special preparation prior to imaging the gallbladder does not required, making this method highly comfortable. Exception would be if the procedure is carried out with contrast — then you need to give up eating at least 4-5 hours before the start of the study and not have a history of Allergy to iodine and seafood, as the contrast agent contains this trace mineral.
It is also recommended to remove all jewelry (rings, piercings etc.) because they tend to change the picture that adversely affect the diagnosis. An important stage of preparation for the CT is to consult a radiologist who knows all the nuances, such as the method of performing the procedure, can justify its security, and describe how to behave during the procedure.
The methodology of the
CT scan duration does not exceed 20-30 minutes, the specific number depends on the capabilities of the device.
It is held in the supine position, with the portion of the apparatus is moving, scanning the region of the stomach, making clicking sounds that are a normal part of the procedure. After the research data are recorded and decrypted.
Under what circumstances should you use this method?
Indications for computed tomography of the gallbladder a lot. CT diagnosis is often prescribed for pain in right side that is radiating to other parts of the body (shoulder, hand), signs of peritoneal irritation, jaundice of skin and sclera.
The procedure can be scheduled if you suspect a gallbladder disease and biliary tract, such as:
- Acute cholecystitis.
- Chronic cholecystitis.
- Various neoplasms (adenocarcinoma, squamous cell carcinoma,
slimy and solid cancer).
- Biliary dyskinesia.
- Acute and chronic cholangitis.
- Cholelithiasis, and others.
Cholecystitis and cholelithiasis are the most common pathologies of the gallbladder. Cholecystitis is an inflammatory disease that occurs due to the action of an infectious factor on the body. It is of two types: acute and chronic. Acute requires immediate surgical intervention and chronic therapy, and both can lead to complications (liver abscess, pancreatitis, empyema, etc.).
Cholelithiasis — pathology, in which the gallbladder to form stones (calculi). Of complications it is possible to allocate colic, cholecystitis and obstructive (mechanical) jaundice.
Contraindications for computed tomography of the gallbladder is a complex condition of the patient, pregnancy, breast-feeding, claustrophobia (fear of closed spaces).
What are the advantages and disadvantages of this method of diagnosis?
One major advantage of computed tomography is able to distinguish between mechanical jaundice from the rest of its subspecies. With CT it is possible to determine the blockage of the bile ducts, and to establish the place and why. It is also possible to differentiate between calcium-containing stones from cholesterol stones in the gallbladder, complications of acute cholecystitis.
Other advantages include: comfort the use of CT, use of contrast methods of diagnostics (computer tomography cholangiography).
The disadvantages include: high cost of research; less informative regarding some other methods of diagnostics, such as ultrasound; a small amount of x-ray radiation, which eliminates the use of this method more often than once in 3-4 months; inability to carry out a study for patients with large dimensions because of the restrictions on weight and dimensions of the device CT.
What are the analogues of this method?
To the main counterparts of CT in studies of the gallbladder are an ultrasound and MRI. Ultrasound, or ultrasonography, is the most informative method in the diagnosis of the body. It perfectly detects most stones, various tumors, determines the cholecystitis. MRI, or magnetic resonance tomography is a highly informative method, it allows you to identify all pathology of the gallbladder. However, it has a significant disadvantage — very high price studies, as the equipment is very complex and expensive.
In conclusion, computed tomography is a necessary method to diagnose pathologies of the gallbladder, however, we can not exclude other research methods that can be more useful and informative. In turn, a CT scan should be used when cases of dispute to clarify or substantiate a diagnosis that is more effective for identifying disease and its subsequent treatment.
