Check the positioning block in the other two planes. Plan the axial slices on the coronal plane angle the position block parallel to the line passing through the medial and lateral humeral epicondyles. T1 weighted low resolution scans can be used for this purpose. Suggested sequence, parameters and planningДЄ three plane localiser must be taken in the beginning to localise and plan the sequences. Register the patient on the scanner as 'head first supine' Position the elbow in small flex coil and immobilize with sand bagsД¬entre the laser beam localiser over the elbow joint Position the patient in supine position with head pointing towards the magnet (head first supine) Offer earplugs or headphones, possibly with music for extra comfort If possible provide a chaperone for claustrophobic patients (e.g. Pregnancy (risk vs benefit ratio to be assessed)ДЄ satisfactory written consent form must be taken from the patient before entering the scanner roomДЄsk the patient to remove all metal objects including keys, coins, wallet, cards with magnetic strips, jewellery, hearing aid and hairpins Intracranial aneurysm clips (unless made of titanium) cardiac pacemaker, insulin pump biostimulator, neurostimulator, cochlear implant, and hearing aids) > Neoplasms of bone, joint or soft tissueДЄny electrically, magnetically or mechanically activated implant (e.g. > Evaluation of intra-articular loose bodies > Evaluation of suspected cartilaginous defects osteomyelitis, osteochondritis, osteoarthritis ) > Infections of bone, joint, or soft tissue (e.g. synovitis, tenosynovitis, bursitis, and ganglion cysts) bone contusions, osteonecrosis, marrow oedema syndromes, and Some indications might benefit from an application of contrast media as e.g.> Marrow abnormalities (e.g. purpose: bone and/or soft-tissue characterization, in particular in tumors or nerve disorders.planes: coronal, axial (optional for nerve tract delineation).purpose: bone and/or soft-tissue characterization, for the delineation of ulnar, median and radial nerve tracts.planes: coronal,В sagittal, axial* (option, beneficial in inflammatory disease), coronal oblique* (option for the assessment of the distal biceps tendon).purpose: detailed anatomy, delineation of the medial (ulnar) and lateral (radial) collateral ligament complex.Most indications for an MRI of the elbow joint do not require any contrast media: The mainstay in musculoskeletal imaging are water-sensitive sequences, this can be achieved with conventional STIR or fat-saturated images or with intermediate,-weighted images.ДЄt least one T1-weighted sequence should be included to ease the assessment and interpretation of bone marrow and/or soft tissue lesions or for the delineation of nerve tracts. volume: distal biceps tendon about in thickness of a biceps belly (10-12 slices)Д¬oronal oblique images might be performed for the evaluation of distal biceps tendon pathology with the arm in a non- FABS position.

the patient is supine with the arm close to the body and full supination.

the patient is prone with the arm in elevation and pronation of the elbow joint (superman position).

Postoperative examinations in patients with metallic implants, however, should be done on 1.5 tesla with metal artifact reduction sequence. They profit from the improved spatial and contrast resolution of 3 tesla.

Musculoskeletal examinations are generally done on both 1.5 and 3 tesla. ulnar, medianВ or radial nerve compression syndromes.elbow instability, posterolateral rotatory instability.Typical indications include elbow pain, decreased range of motion or nerve-related pathologies as in:
