How is an MRI of the elbow done?

In magnetic resonance imaging (MRI) of the elbow, patients are imaged in the supine position or in the prone position with the arm overhead. Imaging begins about 10 cm above the elbow joint and extends to the bicipital tuberosity. Images are acquired in the axial, coronal, and sagittal planes.

What is MSK protocol in MRI?

The MRI pelvis protocol encompasses a set of MRI sequences for the routine assessment of the pelvis. Note: This article aims to frame a general concept of an MRI protocol for the assessment of the pelvis in the setting of suspected musculoskeletal pathology.

What is a 3 plane localizer MRI?

Localizer – a 3-plane localizer or ‘scout’ scan meant to find the subject’s head. It is also be used for prescription for the subsequent scans. Doing some sort of localizer is necessary, and the ‘3planeloc SSFSE’ (single shot fast spin echo) is the standard work-horse used by most CNI users.

How long does a elbow MRI take?

The length of an elbow MRI is typically 20-25 minutes and will require you to hold very still. MRI scans are sensitive to motion and any motion may obscure information the Radiologist uses to make a formal report.

Does your whole body go in for a elbow MRI?

Your whole body does not go in the machine, only the half or part that needs to be scanned. One thing you’ll need to know is that the machine is noisy. It makes a lot of different noises, and some of them are extremely loud. Some patients say it sounds like a sledgehammer.

What can I expect from an elbow MRI?

What should you expect during an elbow MRI scan? When you go in for your elbow MRI, you’ll answer a few questions, then proceed with the scan. You’ll need to remove earrings and other metal objects that could interfere with imaging. The scan could take an hour or more, but most elbow MRIs take from 30 to 60 minutes.

What is a fiesta MRI sequence?

FIESTA (Fast Imaging Employing Steady-state Acquisition) is the GE name for a balanced steady-state gradient echo sequence that Siemens calls TrueFISP and Philips calls balanced-FFE. As described in a prior Q&A, these sequences may be affected by phase shift errors across the image that produce banding artifacts.

What is signal dropout MRI?

When the susceptibility gradient adds to one of the scanner’s gradients in a way that the resulting gradient experienced by the water molecules in a particular region is not what we intended, then signal drop-out can result.

What is the protocol for an MRI scan?

Protocol specifics will vary depending on MRI scanner type, specific hardware and software, radiologist and perhaps referrer preference, patient factors e.g. implants, specific indications and time constraints Typical indications include elbow pain, decreased range of motion or nerve-related pathologies as in:

Do I need contrast media for an MRI of the elbow?

Most indications for an MRI of the elbow joint do not require any contrast media: Some indications might benefit from an application of contrast media as e.g. nerve-related issues, tumors or inflammatory disease

How do you do an elbow scan with a magnet?

Position the patient in supine position with head pointing towards the magnet (head first supine) Position the elbow in small flex coil and immobilize with sand bags. Centre the laser beam localiser over the elbow joint. Register the patient on the scanner as ‘head first supine’.

How do I perform an elbow biopsy?

Position the patient in supine position with head pointing towards the magnet (head first supine) Position the elbow in small flex coil and immobilize with sand bags Centre the laser beam localiser over the elbow joint Register the patient on the scanner as ‘head first supine’
