All images obtained using digital system are called digital xrays the common digital method used is the CR System that produces digital xrays on a computer.
These are studies of the gastrointestinal tract performed using barium sulphate and XRays. Barium studies are different type depending on the area being examined. We have Barium Swallow, Barium Meal, and Barium MealFollow through, Barium Enema. What Preparation isrequired?

In this procedure, a dye is injected intravenously pictures of the kidneys, uterus and bladder are obtained. The dye is radioopaque and seen well with xrays. Overnight fasting and good preparation of the colon with laxatives are required.
It is a special Xray procedure that is done with contrast dye to visualize any abnormal opening (sinus) in the body. The contrast is injected via a rubber catheter. Serial xray pictures are taken to show the extension of the fistula.
A fistulagram is a study of a fistula. During a fistulagram, a patient lies on an exam table. The fistula is cleaned and then an injection is given to numb the area. A needle is then placed in the fistula and a wire is put inside the needle. The wire is left in the fistula and the needle is removed, allowing a catheter to be placed over the wire and into the fistula. Contrast dye is injected through the catheter while Xrays are taken in rapid sequence. This allows the doctors to see how the vein and artery in the fistula are shaped. If nothing is wrong, the catheter is removed and the patient can go home.
Retrograde Urethrogram (RUG) A retrograde urethrogram allows us to evaluate any structural abnormalities in the urethra including narrowed areas (strictures or contractures) and outpouchings (diverticulum). This diagnostic test is commonly performed in male patients when narrowing of the urethra is suspected.
