Why you may need MRI of the knee?

Magnetic resonance imaging (MRI) of the knee bone uses a strong magnetic field, radio waves, and a computer to produce pictures of the structures inside the knee joint. It is usually used to help diagnose or evaluate pain, weakness, swelling or bleeding in and around a joint. MRI test lab in Delhi does not use ionizing radiation and can help determine if you need surgery.

Talk to your physician about any health problems, recent surgeries or allergies, and whether there is a possibility that you are pregnant. The magnetic field is not harmful but can cause the malfunction of some medical devices. Most orthopedic implants do not present a risk, but you should always let the technologist know if you have an appliance or metal in your body.

Why you may need MRI of the knee?

The rules about foods and beverages before your examination vary according to the care center. Unless you are instructed otherwise, take your regular medications regularly. Leave the jewelry at home and wear loose and comfortable clothing. You may be requested to put on a gown during the exam. If you have claustrophobia or anxiety, you can ask your doctor to give you a moderate sedative before the test.

Some common uses of the procedure

In combination with conventional X-rays, MRI is, in general, the best option to examine the most important joints of the body, such as the knees.

The test is usually done to diagnose or estimate:

  • Knee pain, weakness, bulging or bleeding in the tissues in and around the joint
  • Damaged cartilage, menisci, ligaments or tendons
  • Knee injuries as a result of sports activities, such as sprains, strains of ligaments and strains of muscles
  • Bone fractures that may not be detected by x-ray or other imaging tests
  • Degenerative disorders of the joints, such as arthritis
  • Accumulation of fluid in the knee joint
  • Infections (such as osteomyelitis )
  • Tumors (primary tumors and metastases ) that involve bones and joints
  • A feeling that your knee is collapsing in the joint
  • Reduced mobility of the knee joint
  • Injuries or pain in the kneecap
  • Complications related to implanted medical devices

Your surgeon may also order an MRI to determine if knee arthroscopy or another surgical method is required and to monitor your progress after knee surgery.

A particular form of MRI called MR arthrography involves the injection of contrast agents into the joint so that the radiologist can obtain better visualization of the relevant structures.

What does MRI of the knee consist of?

MRI Test of the knee provides detailed images of the structures within the knee joint, including bones, cartilage, tendons, ligaments, muscles and blood vessels from many angles.

Nuclear magnetic resonance (NMR) is a non-invasive medical examination that doctors use to diagnose diseases.

MRI uses a powerful magnetic field, pulsed radiofrequency and a computer to create detailed images of organs, soft tissues, bones, and practically the rest of the internal structures of the body. MRI does not use ionizing radiation (X-rays).

The detailed images obtained with the MRI allow physicians to evaluate various parts of the body and determine the presence of specific diseases. In this way, images can be examined on a computer monitor, transmitted electronically, printed or copied to a CD, or uploaded to a digital server in the cloud.
