The Northern Manhattan Study (NOMAS) MRI study included 1290 individuals: 1) age ≥50 years, 2) without MRI contraindications, 3) without clinical stroke and 4) able to provide signed informed consent. Imaging was performed on a 1.5T MRI (Philips Medical Systems, Best, Netherlands), including axial T1, axial T2, axial proton density, dual-spin echo, diffusion weighted imaging, and FLAIR sequences. IRBs at Columbia University and University of Miami approved this study.
1.5t mri
Manufactured by Philips
Sourced in Netherlands
The 1.5T MRI is a magnetic resonance imaging (MRI) system that operates at a magnetic field strength of 1.5 Tesla. It is designed to capture high-quality images of the internal structures of the human body. The core function of the 1.5T MRI is to provide detailed anatomical information to assist healthcare professionals in diagnosis and treatment planning.

The hips were scanned using 1.5T MRI (Philips, Achieva, The Netherlands) within 24 h of death. Take the fetus in supine position, straighten the lower limbs together, moderately press the calf and bilateral hip joints with sandbags, and place the midpoint of the connecting line of bilateral hip joints at the center of the coil. T2-weighted images (T2WIs) were obtained using eight-channel SENCE cardiac coils in T2-weighted fast spin-echo (repetition time 2,137 ms; echo time 92 ms; time of acquisition 2 min 36 s; seam thickness 2 mm; matrix 110 × 110) in the transverse plane. The remaining imaging parameters varied slightly based on the size of the fetus. The scanning methods are mentioned in Whitby's study (12 (link)). The scan took approximately 20 min.

Liver MRE was obtained for clinical purposes in some of the study population. For all MRE examinations, patients were kept NPO (nothing by mouth) for at least 6 hours before the examination. MRE was performed on 1.5 T MRI Philips scanners. The details of our institutional protocol have been previously described.13 (link)

All subjects had a preoperative 3T or 1.5T MRI (Philips, Eindhoven, The Netherlands) in case of an implanted vagal nerve stimulator. The sequences used were a 3D T1 with gadolinium (voxel sizes: 1 × 1 × 1 mm, TE/TR of 3.7/8.1 ms), axial T2 (voxel sizes: 0.45 × 0.45 × 2 mm, TE/TR of 80 ms/8264 ms), and a T1 inversion recovery (voxel sizes: 0.34 × 0.34 × 2 mm, TE/TR/TI of 10/7362/400 ms). Postoperative CT (Siemens, Erlangen, Germany) or 1.5T T1 (voxel sizes: 1 × 1 × 1 mm, TE/TR of 4.6/9.3 ms) MRI was performed for DBS lead localization in the week following DBS surgery.

Cardiac imaging was performed using short‐axis, breath‐hold, ECG‐gated cine sequence, 1.5‐T MRI (Phillips Medical Systems) in DHS1 and 3.0 T (Phillips Medical Systems) in DHS2. Endocardial and epicardial borders at end diastole and end systole were manually traced in each short‐axis image from apex to base using QMass software (Dallas, TX) to calculate left ventricular (LV) volume and LV mass. Measurements from each slice were summed by the method of disks (Simpson rule). Papillary muscles were included in myocardial LV mass and excluded from LV volume measurement. LV wall thickness was obtained from short‐axis images, as previously described.13 LV concentricity was defined as LV mass/LV end‐diastolic volume (LVEDV). In DHS1, left atrial (LA) images were acquired using prospective electrocardiographic gating and turbo field echo sequencing. In DHS2, LA images were acquired using retrospective ECG gating and balanced fast field echo sequencing. Maximum LA volume was measured using the biplane area‐length method.14 Several cardiac structural and functional measurements were assessed, including LVEDV (mL), LV end‐systolic volume (LVESV; mL), LA end‐diastolic volume (mL), LV mass (g), LV wall thickness (mm), LV concentricity (g/mL), and LV ejection fraction (LVEF; %).

Structural MRI of all participants were scanned in a 1.5 T MRI (Philips Medical Systems, Netherlands) using a high-resolution, T1-weighted, 3D gradient-echo pulse sequence: field of view (FOV) = 240 × 240 mm, acquisition matrix =256 × 256, spin-echo repetition time (TR) =25 ms, echo time (TE) =4.6 ms, flip angle = 30°, slice thickness = 1.2 mm, slice gap = 0 mm). The offline MEG and MRI co-registration was performed using the fiducial markers (nasion, left and right external acoustic meatuses) by a manual method.

The enrolled 22 patients received 2-stage GKRS, and the procedure for the two treatments was similar. First, installation of the Leksell head frame was performed after the diagnosis was confirmed and the treatment consent was signed. MRI T1, T2, FLAIR, and enhanced axial and coronal sequences were obtained via a Philips 1.5T MRI. After the thin and high-resolution MR images were transferred to the Elekta Leksell Gamma Plan system, sensitive tissues surrounding the tumor and outline of CSHs were sketched out, and the GKRS treatment protocols were formulated by the neurosurgeon and radiation physicist. The second GKRS treatment was be performed when CSHs were reduced significantly at the first review, which was usually performed 6 months after the first GKRS treatment. All of the patients were treated with the Elekta Gamma Knife.

In the EH, the MRI scans were performed on a 1 Tesla (T) MRI (only in 2008), a 1.5 T MRI (2009-2014), and a 3 T MRI (2011-2014) (all Phillips Medical Systems). The scanning protocol differed over time and per MRI scanner, however in all patients, FFE imaging was performed as well as T2 sagittal imaging. Diffusion weighed imaging was performed when cerebral ischemia was suspected. In the UMCG, all the MRI scans were performed on a 1.5 T scanner (Siemens Medical Systems). T2*GRE and T2 sagittal imaging were performed in all patients.
All MRI scans were initially assessed by a neuroradiologist and reassessed for DAI grading by a researcher (M.v.E.). In cases of inconclusive assessment, a neuroradiologist ( J.P.) was consulted.

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.
