A knee X-ray can help find the causes of common signs and symptoms such as pain, tenderness, swelling, or deformity of the knee. It can detect broken bones ,dislocated joint or arthritis in the joint. After a broken bone has been set, the image can help determine whether the bone is in proper alignment and whether it has healed properlyWhat 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.
Lower limb radiography is the radiological investigation of the pelvis, hip joint, femur, knee joint, tibia, fibula, ankle joint, tarsal bones of the foot and metatarsals. A lower extremity X-ray is a test that uses radiation to produce detailed images of the bones of the lower extremity. A lower extremity X-ray may be ordered to evaluate for various injuries and conditions, including: fractures (breaks), dislocations (joints that are pulled or pushed out of their normal position), Arthritis, unexplained swelling or pain bone deformities, tumors (abnormal masses of cells), infections, assist in the detection and diagnosis of bone cancer, locate foreign objects in soft tissues around or in bones. In addition, an upper extremity X-ray may be used after treatment to ensure that a fracture has been properly aligned and stabilized for healing.
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 is harder to read than PA x-rays and is 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. The oblique view is 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. The knee skyline Laurin view is one of many different methods to obtain an axial projection of the patella. This projection is best suited to patients able to maintain a semi-recumbent position on the examination table.

An X-ray (been used for decades) is an imaging test that uses small amounts of radiation to produce pictures of the organs, tissues, and bones of the body. It can help your doctor view the inside of your body without having to make an incision. This can help them diagnose, monitor and treat many medical conditions. Different types of X-rays are used for different purposes. An X-ray PA Left Knee can help find the causes of common signs and symptoms such as pain, tenderness, swelling or deformity of the knee. It can also detect broken bones, dislocated joint or arthritis in the joint. After a broken bone has been set, the image can help determine whether the bone is in proper alignment and whether it has healed properly. Different parts of the body behave differently with X-rays. X-rays work because the body's tissues vary in density (thickness). Each type of tissue allows a different amount of radiation to pass through and expose the X-ray-sensitive film. For example, bones are very dense and most of the radiation is prevented from passing through to the film. As a result, bones appear white on an X-ray. Tissues that are less dense such as the lungs are filled with air and allow more of the X-rays to pass through to the film and appear on the image in shades of gray. There are some risks involved in getting an X-ray. But for most people, the potential benefits outweigh the risks.
