Parameter Decoding:
I5 – Turbo Factor (TSE Factor) = 5

Indicates a Turbo Spin Echo (TSE) sequence where 5 echoes are acquired per excitation pulse for faster imaging.

Description: "Turbo spin echo with a turbo factor of 5."

E5 – Echo Train Length (ETL) = 5

Synonymous with Turbo Factor, specifying that 5 echoes are generated per RF pulse.

Description: "Echo train length of 5."

D – Diffusion-Weighted Imaging (DWI) Mode

Suggests the sequence includes diffusion-weighting (if active, depends on protocol settings).

Description: "Diffusion-weighting capability (b-value dependent on protocol)."

Note: In some Siemens sequences, 'D' may represent other features (e.g., driven equilibrium).

-M – Multi-Slice Acquisition

Enables simultaneous imaging of multiple slices per TR.

Description: "Multi-slice mode for efficient volume coverage."

Full Sequence Description (Example):
*"A rapid Turbo Spin Echo (TSE) sequence configured with a turbo factor of 5 and echo train length of 5, optimized for multi-slice acquisition. The 'D' component implies optional diffusion-weighting, typically used in neuroimaging (e.g., stroke evaluation) when enabled with appropriate b-values. Standard applications include T2-weighted anatomical imaging with reduced scan time."*

Notes for Clarity:
Clinical Context: This sequence is likely a T2-weighted TSE (common for brain/spine/abdomen) but may serve other weightings if parameters (TR/TE) are adjusted.

Protocol-Specific: Confirm exact settings (e.g., b-values for DWI, fat suppression) in the system’s protocol details.

Vendor Variations: Siemens’ nomenclature may vary slightly across platforms (e.g., MAGNETOM Aera/Vida).
