Before the exam, the person will need to drink three glasses of water (about 500 ml) at least one hour before the exam. If the person is on fluid restriction diet (due to heart, liver or kidney problems), then he can ignore the instruction. If there is a urinary catheter, the catheter should be clamped immediately after drinking the water. The ...
Because water is an excellent conductor for ultrasound waves, visualizing these structures often requires a well-filled urinary bladder (this means the patients has to drink plenty of water before the examination). The liver can be imaged by swiping the probe sagittally from medial to lateral at the subcoastal region.
Imaging time is approximately 5 - 10 minutes depending on the views taken. Usually, posterior and oblique views are a must for better interpretation of the scan. Patient is asked to maintain good hydration before and after the radiotracer injection by drinking water or intravenous fluid administration, if patient cannot drink water for any reason.
In upper gastrointestinal series examinations, the barium sulfate is mixed with water and swallowed orally, whereas in the lower gastrointestinal series (barium enema), the barium contrast agent is administered as an enema through a small tube inserted into the rectum. [2] Barium swallow X-ray examinations are used to study the pharynx [4] and ...
After the scan is complete, the patient is encouraged to eat and drink normally, with special attention to plenty of fluids. The barium sulfate is excreted through defecation , so extra fluid intake helps prevent constipation , which is a possible side effect (see Johns Hopkins Medicine Health Library for an example of a possible patient ...

A computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein. [1]In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
