An MRI of the hip is often used to detect damage or disease in the hip joint. In an MRI the tissues of the hip are stimulated into creating signals through the use of magnetic waves. The signals are then analyzed by a computer and cross-sectional views of the hip joint are obtained. Many a time a hip MRI is recommended along with an arthrogram of the hip. This is an x-ray that is used to evaluate a joint such as the hip or knee. Arthrography is recommended when regular x-rays are enough to detect the problem.
In an arthrogram, a series of x-ray images of the hip are taken by manipulating the joint in different positions. In order to make the tissues of the joint clearly visible in the x-ray images, a contrast medium is injected into the joint. This procedure is often used to detect problems in the shoulder and knee joints, but can also be used in case of other joints such as the hip, wrist, elbow or ankle. Arthrography is prescribed for joints that are experiencing continued pain and discomfort. Dysfunction of the joints is also another reason why an arthrogram may be performed. Arthrography may also be performed in order to detect abnormalities in the ligaments and cartilage of the joint, to identify damage arising from recurring joint dislocations and to detect synovial cysts.
Prior to the procedure, the individual may discuss any doubts and concerns with the doctor such as the amount of radiation that it involves or the risks associated with the process. A single procedure does not really carry any risk of damage due to radiation. Exposure to radiation over a prolonged period of time due to recurring x-ray tests and treatments may be associated with a slight risk. Allergies to the contrast medium, certain medications, anesthesia, iodine and latex must be discussed with the doctor before the procedure. In rare cases, an allergic reaction to the contrast dye may take place or infection may develop at the site of puncture. Intake of blood thinning medications, aspirin and other medications that affect blood coagulation must be discontinued well before the arthrogram.
Following the procedure, the joint must remain at rest for a period of twelve hours. A small amount of pain and swelling is likely to occur in the area of the joint. The swelling may be alleviated through the use of cold packs, while mild pain relievers may be taken to ease the pain.
