X-ray imaging is perhaps the most commonly known form of diagnostic testing. Similar to visible light, x-rays use electromagnetic radiation, which contain wave-like forms of energy. The energy found in electromagnetism comes from tiny, powerful particles called photons.
NYMI Associates was the first Imaging Center in Manhattan to install a digital x-ray system. Digital x-ray allows the technologist to see the images they have taken of the patient within 10 seconds of making the exposure. It allows the radiologist immediate access to any and all cases requiring an immediate read. It saves the patient from any additional exposure as a result of images being too dark or too light, as the computer can manipulate all images once acquired.
We are dedicated to maximizing image quality, minimizing patient exposure and all in the shortest time possible.
In x-rays, the wavelengths are shorter and the photons hold more energy than those of visible light do. These shorter wavelengths allow for penetration and imaging of the human body. The X-Rays photons also deposit engergy in the body in the form of “ionization” or ejection of electrons from atoms. There are two different types of x-ray imaging: fluoroscopy, which a moving x-ray camera and a monitor displaying the moving images, and radiography, which uses static film technology.
Because this diagnostic test does involve exposure to ionizing radiation, modern machines are more precise in targeting an area with x-rays so as not to expose other areas of the body needlessly. In addition, a heavy, lead cover may be placed over the patient to prevent unnecessary exposure to radiation. Women who are pregnant or have reason to believe they might be pregnant should consult their physician before having an x-ray test.
X-Rray testing can look at any bone structure or organ of the body, including:
- Esophagram and/or GI and/or Small Bowel – Nothing to eat or drink 12 hours prior to the exam. After the study, take a laxative (3 tbsp. Milk of Magnesia).
- GI Series/Esoph – Nothing to eat after midnight. Clear liquids up until 4 hours before exam. GISB –npo after midnight.
- Barium Enema and Air Contrast – Clear liquid diet for 24 hours prior to the exam. Liquids include clear juices such as apple, cranberry, and grape, clear soups, Jell-O, coffee or tea. No milk products or carbonated beverages. At 8 PM the night before – drink one 10 oz. bottle of citrate of magnesia. At 10 PM the night before the exam – take 4 Ducolax pills with water. Beginning at 8 PM until bedtime, drink four 8-oz. glasses of water. On the morning of the exam you may have any liquid listed above. After the study, take a laxative (3 tbsp. of Milk Magnesia).
- Plain X-Rays – No preparation necessary
