Fluoroscopy
Fluoroscopy is a diagnostic and interventional radiological method that uses a dynamic RTG image display (e.g. to display esophageal peristalsis , stomach, intestines, observation of breathing movements or heartbeat). To reduce the radiation load, a pulse mode is used, when the image is created, for example, 4 times'' per second (not continuously) and low values of mAs with automatic control of the kerm příkonucontrol.
Examination Types[edit | edit source]
Monocontrast - Using only positive contrast material (this method is mainly used in children).
Double-contrast - Use of positive and negative contrast material.
For women of childbearing age, the effort is to follow the so-called 10-day rule. The examination is performed during the first 10 days of the menstrual cycle, when higher doses of radiation are applied to the abdominal area.
Types of contrast agents[edit | edit source]
Negative - air (irrigography), methylcellulose (enteroclysis).
Positive – barium suspension, iodine contrast agents.
Fluoroscopy methods[edit | edit source]
The fluoroscopy methods include:
- X-ray examination of the digestive tract: X-ray of the esophagus, videofluoroscopy, X-ray of the stomach, X-ray passage, enteroclysis, irigography, defecography, introduction of stents under RTG control.
- Examination and intervention of the urinary tract: ureterocystography, introduction of pig-tail catheter.
- Fistulography: injection of the mouth of the fistula or drain contrast agent.
- Skiascopy of the diaphragm: diagnostics paresis diaphragm.
- Skiascopy of the lungs: differentiating a nodule in the lung parenchyma from extraparenchymal lesions or summations.
- Cholangiography: intraoperative, T-drain, PTC ( percutaneous transhepatic cholangiography), ERCP.
