Sciascopy

Sciascopy is a diagnostic and interventional radiological method that uses dynamic imaging of an X-ray image (e.g. for imaging peristalsis of the esophagus, stomach, intestines, observation of respiratory movements or heart pulsation). To reduce the radiation load, a pulse mode is used, where the image is created e.g. 4 times per second (not continuously) and low mAs values with automatic kerm power control .

Examination Types[edit | edit source]

Monocontrast – Use of 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.

Methods in Sciascopy[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 , irrigography , defecography , introduction of stents under X-ray control.
Urinary tract examination and intervention: ureterocystography , insertion of a pig-tail catheter .
Fistulography: injecting the mouth fistula or drain with a contrast agent .
Diaphragm sciascopy: diagnosis of diaphragmatic paresis .
Sciascopy of the lungs: differentiation of a nodule in the lung parenchyma from extraparenchymal lesions or summations.
Cholangiography: intraoperative, T-drain , PTC (percutaneous transhepatic cholangiography) , ERCP .
