In fluoroscopic examinations, X-rays are used for real-time imaging of moving objects. The images can concurrently be observed on a monitor. Contrast medium is used in most examinations. The type of contrast medium and its method of administration vary depending on the examined object. The contrast medium in bowel imaging can either be drank or be given orally or transrectally through a tube. When the urinary tract is examined, the contrast medium can be injected into an artery or through a catheter straight to the urinary tract. When a joint is examined, the contrast medium is injected to it with a needle.
The duration of the examination varies depending on the scanned object and its function. The examination usually takes about 30 to 60 minutes. If the contrast medium advancement in the bowel is examined, follow-up images can be taken within a timeframe of several hours.
As a rule, the examination is not performed on pregnant patients. A radiographer or a radiologist is present during most of the examination.
