Recommended Sternoclavicular (SC) Joint MRI Protocols, Parameters, and Planning

localiser 1

To localize and plan the sequences, it is essential to acquire a three-plane T2 HASTE localizer initially. These fast single-shot localizers have an acquisition time of under 25 seconds and are highly effective in accurately localizing chest and abdominal structures.

MRI STERNUM LOCALIZER

localiser 2

For proper planning of sternum scans, it is necessary to include a second two-plane localizer. The two-plane localizer should be positioned on the sagittal plane. Align the planning block parallel to the sternum for the coronal plane and perpendicular to the sternum for the axial plane.

T2 tse sagittal 3mm SFOV

Plan the sagittal slices on the coronal plane; angle the planning block parallel to the manubrium of the sternum. Verify the planning block in the other two planes. Ensure an appropriate angle is set in the axial plane, perpendicular to the sternum’s manubrium. The slices should adequately cover the sternum and sternoclavicular joint from the middle of the right subclavian groove to the middle of the left subclavian groove. To minimize ghosting artifacts caused by heartbeats and breathing, consider utilizing a saturation band over the chest. Please use a head-to-feet phase encoding direction to avoid artifacts originating from the chest.

Plan the coronal slices on the sagittal plane and position the planning block parallel to the manubrium of the sternum. Verify the planning block in the other two planes. Maintain an appropriate angle in the axial plane, horizontally across the manubrium of the sternum. Ensure that the slices adequately cover the sternoclavicular joint from the front to the back. To minimize ghosting artifacts caused by breathing and heart motion, consider using a saturation band over the chest. Please use a right-to-left phase encoding direction to avoid artifacts originating from the chest. Use a smaller field of view (FOV) to achieve the best results.

T1 tse axial 3mm SFOV

Plan the axial slices on the sagittal plane and angle the planning block perpendicular to the manubrium of the sternum. Verify the planning block in the other two planes. Ensure an appropriate angle is given in the coronal plane, perpendicular to the manubrium of the sternum. The slices should sufficiently cover the sternoclavicular joint, ranging from two inches above the suprasternal notch down to the sternal angle. To minimize ghosting artifacts resulting from breathing and heart motion, apply a saturation band over the chest. Please use a right-to-left phase encoding direction to avoid artifacts originating from the chest.

Gadolinium-enhanced sternoclavicular joint MRI scans are reserved for highly uncommon occurrences involving tumors or infections. In such instances, T1 fat-saturated axial and coronal fat-saturated scans are conducted following the administration of gadolinium DTPA. Please utilize the same T1 pre-contrast sequences with fat saturation, but reduce the resolution by one step. The resolution adjustment is necessary to enhance the signal-to-noise ratio, which may be compromised by fat saturation. For specific details and dosage recommendations of gadolinium from different manufacturers, kindly refer to the provided document.
