Dynamics instead of statics
Unlike the image, the copy shows the process: the pendulum-like movement of the contents in the swollen loops confirms mechanical obstruction, and the uniform distribution of gas with sluggish peristalsis confirms intestinal paresis; limited mobility of the dome of the diaphragm indicates a subdiaphragmatic abscess or pleurisy. When monitoring the barium passage, images/scopies after 3–6–12 hours document the advancement of contrast - a delay at one level localizes the obstacle and determines the indications for surgery. The dose with modern pulsed scanning is minimal.
Indications
- acute abdominal pain - exclusion of obstruction and perforation (survey image);
- dysphagia, stomach pain, suspicion of an ulcer and tumor—scopy/barium graph;
- injuries and pain in the pelvic area - photographs of the pelvic bones;
- fistulas after operations and inflammation - fistulography;
- control of the chest organs in motion (diaphragm, mediastinum).
Copy and graphics
X-ray is a picture that records the condition of an organ; fluoroscopy - real-time observation showing motility: peristalsis of the stomach and intestines, mobility of the diaphragm, the passage of barium through the esophagus and pylorus. Therefore, for functional tasks (impaired swallowing, gastric evacuation, suspected dynamic obstruction), a copy is used, and to document the morphology (ulcer niche, filling defect in a tumor, mucosal relief) a series of targeted images is used; often methods are combined in one study.
