Default coils in the spine generic protocol.
(i) posterior spine coil could also be used depending on coverage, (ii) for thoracic/lumbar SC imaging; anterior coil could be used to improve image quality in sequences with anterior-posterior phase-encoding.
The relevant elements of the spine array are to be selected depending on the region to cover. When using “auto select” (Siemens) or “SmartSelect” (Philips), elements will be automatically selected based on the slice positioning. It is advised to use it.
