XRay - PARANASAL SINUSES What are X-rays? X-rays are electro-magnetic radiations that are produced by special machines called X-ray machines. These cannot be seen, felt or heard. How do X-rays work? Chest X-rayDifferent parts of the body behave differently with X-rays. While scanning chest X-ray , structures such as bone absorb X-rays, whereas air in the lungs lets all X-rays pass through. Thus, when X-rays pass through the body, when they come out, they have different strengths, depending on what parts of the body they have passed through. When these X-rays hit a film (like a photographic film), that film gets exposed depending upon this variation. Like a photographic film, this special film also needs to be developed, before we can see the final picture. Where are X-rays useful? X-rays have been used to view all parts of the body. Specifically, they are required for chest, all bones, joints and abdomen. Are there any dangers? Since X-rays involve radiation, there is a theoretical risk, though none in practice. In women who are pregnant, X-rays should be performed only after weighing all the risks. What are the dyes used with X-rays? X-RaysSometimes, artificial dyes are used to improve our ability to see internal structures. The common dyes used are either barium containing (barium sulphate) or iodine dyes. Barium sulphate is used for all barium examinations to study the stomach and intestines. Iodine dyes are usually injected in the veins to study the kidneys or during angiography, etc. Are there any complications of the dye? Five percent of the patients may get nausea and redness of skin. Though severe reactions are known, these are very rare and uncommon. However, in patients who have a previous history of allergy, asthmatics, those with renal and cardiac failure, a special dye is used which is more expensive but safer.
This X-ray helps detect problems with the sinuses. This is most often due to inflammation or a build-up of fluid in the sinuses. It's a non-invasive test that can be completed quickly and with little discomfort or pain.
The most common X-ray views are poster anterior, anteroposterior, and lateral. In a poster anterior (PA) view, the x-ray source is positioned so that the x-ray beam enters through the posterior (back) and exits out of the anterior (front), where the beam is detected. To obtain this view, the patient stands facing a flat surface behind which is an x-ray detector. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect. AP are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. Lateral views are obtained in a similar fashion as the poster anterior views, except in the lateral view, the patient stands with both arms raised and the side of the chest pressed against a flat surface. Oblique view are projection taken with the central ray at an angle to any of the body planes. It is described by the angle of obliquity and the portion of the body the X-ray beam exits; right or left and posterior or anterior. Right or left as stated above indicates the portion of the body the X-ray beam exits. The axillary view is useful for detecting anterior or posterior dislocations that are not evident in the AP view.

A X-ray Paranasal sinus (or sinus series) is an imaging test that uses a small amount of radiation to visualize details of your sinuses. Sinuses are paired (right and left) air-filled pockets that circumscribe the nasal structures. The function of the sinuses is debated, but possibly include humidifying the air breathed through your nose and providing shape to your face. A sinus X-ray helps doctors detect problems with the sinuses. Sinuses are normally filled with air so the passages will appear black on an X-ray of healthy sinuses. A grey or white area on an X-ray of the sinuses indicates a problem. This is most often due to inflammation or a build-up of fluid in the sinuses.
