Recommendations for reporting of parameters of the acquisition sequence.

Item	Notes	Recommended
Acquisition sequence type	2D vs 3D; GRE vs EPI etc.;	essential
Acquisition sequence commercial name	e.g. “SWAN”, “MERGE”, “SWlp”…
k-space sampling trajectory scheme	cartesian vs spiral vs radial etc.	essential, if not cartesian
Acquisition orientation	pure axial vs sagittal vs oblique
Number of echoes, TE1:ΔTE:TEmax	e.g. 7 echoes, TE = 5:5:35 ms	essential
TR		essential
FA
Pixel Bandwidth or Receiver Bandwidth [Hz]	DICOM tag (0018, 0095)
Spatial coverage (FOV) and acquisition matrix size		essential
Voxel Size	Attention: it can be different from “FOV divided by matrix size”	essential
Monopolar vs bipolar echoes	Indicate if the sequence produces monopolar of bipolar echoes
Average ± std center frequency [MHz]	In multi-scanner studies, mean ± std center frequency shall be reported for data from each scanner. For example, Siemens “3T” scanners systematically operate at <2.9T. DICOM tag (0018,0084)	essential for multi-scanner studies; unnecessary for single-scanner studies
Flow compensation	Yes / no; if yes, please indicate the compensated echo(s): all vs only the first one; and direction (full, phase)
Acceleration type and factor	Yes / no. If yes: SENSE (or ASSET) vs GRAPPA (or ARC), compressed SENSE, etc.; indicate phase factor and slice factor (if 3D)	essential
Partial Fourier factor	Use should be avoided. If used, indicate partial Fourier factors in phase and slice direction	essential, if used
Partial echo (GE/Philips) aka Asymmetric echo (Siemens) aka Half echo (Hitachi)	Use should be avoided.	essential, if used
Elliptical k-space shutter	Yes / no.
Phase stabilization	Option available only in particular implementations. If the option is available, indicate Yes / no	(essential if used)
Excitation pulse	Fat-sat vs Water-only
Scan duration		essential
