All bilateral breast MRIs were performed on a Philips Achieva TX scanner (Philips Healthcare, Best, the Netherlands). Each MRI included the following sequences: T2-weighted fast spin echo sequence, T1-weighted non-fat suppressed sequence, T1-weighted fat-suppressed DCE MRI sequences before and after contrast administration, and a DWI sequence. All scans were acquired in the axial orientation. The DCE MRI protocol was in compliance with the American College of Radiology breast MRI accreditation program, and was performed using a T1-weighted 3D turbo field echo sequence with parallel imaging (THRIVE) with 1.3 mm slice thickness, FOV = 32-38 cm, and 660 × 672 matrix, yielding 0.5 mm in-plane resolution. DWI was performed using a diffusion-weighted EPI sequence with parallel imaging (reduction factor = 3); TR/TE = 8000/63 msec, 2 averages, matrix = 240 × 288, FOV = 36 cm, slice thickness = 4 mm, gap = 0 mm, and b = 0 and 800 s/mm2.

All participants underwent a structural MRI scan. Imaging was performed on a 3T Philips Achieva TX scanner at IRM Québec-Mailloux in Québec City. High-resolution T1-weighted structural images were acquired with a volumetric magnetization prepared rapid gradient echo (MP-RAGE) sequence (repetition time = 8.2 ms, echo time = 3.7 ms, field of view = 250 mm, flip angle = 8°, 256 × 256 matrix, 180 slices/volume, slice thickness = 1mm, no gap).

Whole-brain functional images were collected on a 3 T Philips Achieva TX scanner at Columbia University’s Program for Imaging in Cognitive Science (PICS). Structural images were collected with high-resolution T1 spoiled gradient recall images (SPGR), which allow for anatomical localization and warping to standard space. For functional EPI image collection, the following scanning parameters were set: TR = 2000 ms, TE = 20 ms, field of view = 224 mm, 64 × 64 matrix, 3 × 3 × 3 mm3 voxels, 42 interleaved slices, parallel imaging, SENSE factor 1.5. E-Prime software (PST Inc.) was used to control stimulus presentation and collect behavioural data.

The MRI examination was held on a 3T Achieva TX scanner (Philips Healthcare; Best, The Netherlands) with the use of a 32-channel head coil. The structural imaging protocol included T1-weighted turbo field echo [repetition time = 8.1 ms, echo time = 3.7 ms, voxel size 1 × 1 × 1 mm, field of view (FOV) 260 × 252 × 160 mm, flip angle: 8°], T2-weighted turbo spin echo (repetition time = 3683 ms, echo time = 80 ms, voxel size 1.2 × 1.2 × 2 mm), fluid attenuation inversion recovery (FLAIR: repetition time = 9000 ms, echo time = 125 ms, voxel size 1 × 1,1 × 4 mm) and diffusion-weighted imaging (b = 0, 500, and 1000 mm2/s, repetition time = 3951 ms, echo time = 83 ms, voxel size 1.5 × 1.9 × 4 mm) sequences.
The blood oxygen level-dependent signal during the Stroop task was collected with the T2∗ Gradient Echo-Planar Imaging sequence (FFE-EPI: 37 axial slices, repetition time: 2000 ms, echo time: 30 ms, flip angle: 90°, matrix: 64 × 64, slice thickness: 3 mm, 420 volumes, voxel size 3 × 3 × 3 mm, acquisition time 14 min, FOV = 250 mm). Functional imaging was preceded with 4 dummy-scans.

Patients were examined on a 3.0T Achieva TX scanner (Philips Medical Systems, Best, The Netherlands) using an endorectal coil (Medrad, Pittsburgh, PA) inflated with 60 mL of perfluorocarbon in combination with a phased‐array surface coil. For T2W‐MRI, a turbo spin‐echo sequence was used to acquire MR images in the transverse plane, using the following parameters: TR/TE = 3643/110 msec; four averages; matrix size, 220 × 184; slice thickness, 2.2 mm; slice separation, 0.1 mm; right–left field of view, 140 mm. DW‐MRI was performed with an echo‐planar sequence with matrix size, 176 × 176; slice thickness, 2.2 mm; slice separation, 0.1 mm; transverse field of view, 100 × 100 mm, b‐values 0, 100, 300, 500, and 800 s/mm2. Apparent diffusion coefficient (ADC) value maps were computed using a monoexponential fit. (Although we accept that it is commonly standard practice to exclude b = 0 from ADC calculations in order to reduce perfusion effects, that was not regarded necessary here since ADC values were only used to aid tumor identification.)

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
