What to Write in Your Methods Section

Please find below examples of how to describe scans acquired at UBC MRI Research: 
Note: Replace parameters in “[ ]” with those specific to your study as applicable.

Scanner and Coil  

Images were acquired with a Philips 3T [Ingenia Elition X between Jan 2019 and Jan 2024;  MR7700 since Jan 2024] whole body MRI system (Philips Healthcare, Best, The Netherlands), using a [insert coil used here, usually the 32-channel head coil for the brain and a 15-channel head-neck coil with a 12-channel posterior spine coil for the spine].   

Generic 

The sequences were obtained with [# mm isotropic resolution, or resolution of # by #] with [#] mm thick slices and a FOV of [# x # x #] acquired in the [axial/axial oblique/sagittal/coronal] plane. 

VBRAIN 3DT1 0.8mm isotropic 

T1 weighted images of the whole brain were acquired using 3D MPRAGE with the following parameters: [flip angle = 8°, TE/TR = 4.3/2400 ms, inversion time = 950 ms, slices = 225, FOV 256 x 256 x 180 mm3, resolution = 0.8 mm3  isotropic with compressed SENSE factor of 3.6 for a total acquisition time of 5:50]. 

Diffusion Imaging 128dir 

Multi-shell DWI was acquired using single spin-echo echo-planar images [with a multiband acceleration factor of 3. A total of 75 slices and 128 volumes (12xb0, 24xb500, 36Xb1000, 56xb2000) were sampled and interleaved with the following parameters: TE = 79ms, TR = 4000ms, isotropic voxel size of 2mm with a zero mm gap, with a FOV of 224mm]. 

fMRI

[8 min] of resting fMRI data were acquired with an echo-planar imaging sequence with [2.5 × 2.5 × 2.5 mm3 resolution, 240mm FOV, 2000ms TR, 30ms TE, 62 slices with a zero mm gap, 77° flip angle, parallel imaging Sense 2 and Multiband 2].  

pCASL  

[GRASE] sequence was used to acquire a 3D pseudo continuous arterial spin labelling (pCASL) images using the following parameters: [TR/TE = 4000/12 ms, flip angle = 90°, voxel size = 3.75 × 4.0 × 4.0 mm3, 21 slices, for 5 dynamics, post label delay = 2.0 s, label duration = 1.8s and number of phase encoding steps = 60].
