radionuclide study is a way to diagnose kidney, which is administered to a small number of special preparation and obtaining images of the kidneys due to a gamma-camera.These pictures help to diagnose and treat many of the renal pathologies.
The purpose of the survey This method of diagnosis provides an opportunity to receive important information about the functioning of the kidneys.Among the candidates for the body scintigraphy are patients with otsroy or chronic form of kidney failure, obstruction of the urinary tract, kidney artery stenosis, with a transplanted kidney, kidney injury, renal vascular injury, or congenital abnormalities of the body and the ureters.
Preparation for diagnosis
For the radionuclide renal survey does not require special training.But for some varieties of study, you must first drink a special liquid, and immediately before the examination to empty the bladder.
If the patient recently been carried out another similar examination is required at a certain period of time
This diagnosis is performed in a separate medical facility, usually on an outpatient basis.Surveyed have right in front of the camera or under it.Gamma Camera is a special equipment, fixing radiation that emits introduced into the body a medicine.And an image is formed on the image.
radioactive drug is administered intravenously, and immediately after the injection is carried out a survey to assess the blood flow in each kidney.This produces a sequence of images at specified time intervals, depending on the applied medicine.Scanning is required to establish a blood filtration rate in the kidney glomeruli.
Radionuclide examination takes an average of 45 minutes to three hours.The exact time depends on the diagnostic purposes.Basically duration varies within one hour.It is important to understand that scintigraphy to determine the functioning of the kidney, but not always possible to determine the nature of such violations.This diagnosis is very useful for identifying the structure of the kidneys.
Radionuclide diagnosis of kidney reveals normal body work, depending on the age group of the person, his state of health, position, size, configuration and location of the body.
Primary circulation snapshots allow you to set the rate of blood flow in both kidneys.Patients who after scintigraphy confirmed the presence of damage or obstruction, in order to obtain additional information may require additional diagnostic methods such as computed tomography or ultrasound.In addition, when a malformed body size, custom circuit kidneys may need other imaging methods.
Radionuclide body diagnosis is a technologist in the Department of Nuclear Medicine, which was held prior training in working with radioactive drugs and equipment, and processing the resulting survey data.Technologist is required to explain to the patient how the examination is realized, as well as his responsibilities include the introduction of a radioactive drug.
All the data and the history of disease in a patient in order to accurately describe the transmitted specialist radiologists, and patients can read the diagnostic data is already their primary care physician, who sent them for examination.
Complications after inspection
surveys based on nuclear medicine are considered safe.Radioactive substances unlike some contrast agents used during x-ray studies, it is very rarely the cause of side effects.Lasting impact on the body of the radioactive drug is not happening, because humans are exposed to decay very quickly and do not produce any functional effects on the fabric.
After the introduction of these drugs on blood pressure for some time may be reduced or, on the contrary, increase, and there need to urinate.
