CT renal artery angiography
The minimally invasive computed tomography (CT) method of renal artery angiography is used in urological diagnostics to detect various diseases. The kidneys are literally pierced with blood vessels and arteries. Their study using a tomograph allows you to see organs in volume, track their work, detect injuries, abnormalities, inflammation, as well as blood clots, stenoses, aneurysms in the renal veins and arteries. The result of the study is accurate information about the location of the renal vessels, their condition and work.
The study of blood vessels is carried out using x-rays and contrast agents. Time: from 20 to 30 minutes Preliminary preparation: needed Price of CT kidneys in Kiev: from 2800 to 3800 UAH (for three departments). Contraindications:
- • pregnancy;
- • lactation;
- • young children;
- • weight more than 150kg;
- • pulmonary tuberculosis;
- • poor blood coagulability;
- • vascular atherosclerosis;
- • renal, hepatic, heart failure;
- • allergy to iodine;
- • thrombosis;
- • some other conditions.
The purpose of CT diagnostics of the renal arteries
The study allows you to see the location of the kidneys, detect abnormalities, pathologies in their structure and work, possible traumatic injuries. Angiography is the most accurate method for detecting cysts, neoplasms (benign and malignant), their sizes, contours, metastases, as well as damaged renal vessels.
Indications for CT of the renal arteries
- 1. The presence of cysts.
- 2. Disorders in the work of the kidneys.
- 3. Suspicion of oncology.
- 4. The presence of blood in the urine.
- 5. Tuberculosis of the kidney.
- 6. Post-traumatic condition of the kidneys.
- 7. Preparation for the operation.
- 8. Assessment of the state of organs after surgery (removal of stones, kidney transplantation, etc.).
- 9. High blood pressure of unknown origin;
- 10. Renal failure.
How is the CT scan of the renal arteries
Renal vascular angiography is performed using iodine-containing contrast. A bolus is injected by the anesthetist into the lumbar region, or into the femoral artery. Before the introduction of contrast, local or general anesthesia is indicated. The patient is placed on the sliding table of the tomograph on the abdomen (if contrast is introduced into the lumbar region), or on the back with the introduction of a bolus in the thigh. An anesthetist remains with the patient, the radiologist is in the next office. Next, the tomograph scans the area under study, the information is transmitted to a computer, where it is processed by a special program. Volumetric images of organs and renal vessels are displayed on the screen.
What are the risks of CT scan of the renal arteries
The procedure of CT angiography of the renal vessels is carried out on modern equipment that provides the minimum dose of radiation, under the supervision of highly qualified doctors.
How to prepare for a kidney CT scan (angiography)
The procedure of CT kidney angiography is performed using contrast, therefore, preliminary preparation of the patient before the session is necessary:
- • exclusion of alcohol two weeks before the study;
- • exclusion of taking medications such as aspirin one week before CT;
- • shaving the injection site of the contrast (lower back, thigh);
- • diet for two weeks before CT;
- • complete exclusion of food 6 hours before the procedure;
- • morning cleansing enema;
- • water intake (liter) one hour before the session.
The radiologist in our office will carefully study and describe the images taken. The patient is given digital copies of the pictures, their description and the Diagnostic report signed by the radiologist and stamped. The angiographic method is the best way to thoroughly examine the condition, blood circulation and kidney function, identify neoplasms and make the correct diagnosis, on the basis of which the most effective treatment program is developed.
