  • address the issue of the need for knee surgery;
  • diagnosis of tumor and inflammatory diseases.

Indications for magnetic resonance imaging of the hip joint are:

  • osteomyelitis;
  • osteoarthritis;
  • septic arthritis;
  • avascular necrosis of the femoral head;
  • stress fracture;
  • identifying the causes of osteoarthritis.

MRI of the shoulder joint is carried out in the following cases:

  • fractures and dislocations of the shoulder rotators;
  • injuries or ruptures of the cuff muscles;
  • injuries or ruptures of the joint capsule;
  • infringement tendons and nerves.

Magnetic resonance imaging of the ankle joint is indicated for suspected following states:

  • damage to the bones;
  • fracture;
  • torn ligaments or tendons.

How to prepare?

Before examining the patient talking with doctor radiologist (talks about the presence of diseases and allergic reactions) and fills in the necessary documents.In the dressing room the patient removes outer clothing and put on disposable shirt.All metal and ferromagnetic objects on the procedure endure beyond the MRI study.Then, the medical specialist determines the patient's weight and puts it on the platform that drives into a tunnel (a large tube surrounded by a magnet).After confirming that the scanner inside the patient comfortable, the nurse leaves the room, after which the scan is carried out.

Contraindications Absolute contraindications to MRI of the joints is carried over the eye injury, as well as the presence of these foreign objects in the body of the patient:

  • insulin pump;
  • clip cerebral vessels;
  • ferromagnetic and electronic implants;
  • neurostimulator;
  • pacemaker;
  • metal implants and large steel structures.

Relative contraindications to MRI joints are considered:

  • claustrophobia;
  • pregnancy;
  • severe pain;
  • presence of a patient prosthetic heart valves.
