Recommended MR imaging sequences and parameters for the assessment of children with suspected DMSSC

Sequence	Plane	Imaging Parameters	Notes
Essential sequences
3 plane scout/localizer	Axial, sagittal, coronal		For subsequent planning
T1-weighted TSE whole spine	Sagittal	3.0 mm thickness (TR, 600 ms, TE, 30 ms)	—
T2-weighted TSE whole spine	Sagittal	3.0 mm thickness (TR, 3000 ms, TE, 120 ms)	—
T2-weighted FS, Dixon, or STIR	Coronal	3.0 mm thickness (TR, 3000 ms, TE, 40 ms)	FS preferred over STIR; whole spine
T1-weighted TSE	Axial	≤3.0 mm thickness	Lumbosacral region (conus and filum terminale) and the suspected area of abnormality (group of axial images through the disc level not applied)
T2-weighted DRIVE, CISS, or FIESTA	Sagittal	0.6 mm thickness	Sagittal acquisition centered on the area of suspected abnormality with 3D reconstructions
Optional sequences
T2-weighted TSE	Axial	3.0 mm thickness, non-fat-suppressed	Suspected area of abnormality (group of axial images through the disc level not applied)
T1-weighted TSE	Coronal	3.0 mm thickness	Centered onto and along the major axis of the sacrum (for suspected sacral abnormalities)
T1-weighted FS	Sagittal	3.0 mm thickness	Confirmation of lipoma
T1-weighted FS C+	Axial, sagittal, coronal	3.0 mm thickness	Suspected infections/tumors
DWI	Axial or sagittal	3.0–4.0 mm thickness	Suspected dysontogenic abnormalities, epidermoids, dermoids, abscesses
T2-weighted GRE or EPI-GRE	Axial	3.0 mm thickness	Evaluation of bony septum in diastematomyelia
T1-weighted TSE C+	Axial, sagittal, coronal	3.0 mm thickness	Suspected mass lesions, dysontogenic abnormalities, or infections
