Check if the same lab product or an alternative is used in the 5 most similar protocols
Simultaneous acquisition of pH-sensitive information and relaxometry measures of R2′ were performed through modification of a previously described CEST EPI sequence (16 (link)) to include a SAGE-EPI readout (Fig 2). The SAGE-EPI readout consisted of two gradient echoes (TE1=14.0ms;TE2=34.1ms), an asymmetric spin echo (TE3=58.0ms), and a spin echo (TE4=92.4ms). All phantom and human CEST-SAGE-EPI data were acquired with a CEST saturation pulse train consisting of three (3×) 100-ms Gaussian pulses with amplitude B1=6μT, TR>10,000ms, FOV=240×217, matrix size=128×104, partial Fourier encoding =6/8, GRAPPA=3, bandwidth=1630 Hz/pixel, and 25 contiguous slices with a 4mm slice thickness. A total of 29 z-spectral points was acquired with data around +/− 3.0ppm and 0.0ppm with respect to water (from −3.5 to −2.5 in intervals of 0.1; from −0.3 to +0.3 in intervals of 0.1; and from +2.5 to +3.5 in intervals of 0.1). An additional reference S0 scan with identical parameters and no saturation pulse was acquired with NEX=4. The total acquisition time for CEST-SAGE-EPI was 7 minutes and 30 seconds benchmarked on a 3T Siemens Prisma MR scanner (Software Versions VE11A-C; Siemens Healthcare; Erlangen, Germany).

In experiment 1, responses were collected using a generic keyboard; in the MRI scanner, responses were collected with a standard MR‐compatible button box (Current Designs, 8‐button response device, HHSC‐2x4‐C, Philadelphia, USA). With a 3 Tesla Siemens Prisma MR scanner, structural (high resolution T1‐weighted MPRAGE; isotropic voxel resolution 1 × 1 × 1 mm3; 192 sagittal slices) and functional whole‐brain (Gradient‐Echo‐EPI‐sequence; multiband acceleration factor of 2; TR = 1,000 ms; TE = 29 ms; FOV = 216 mm; flip angle = 62°; distance factor = 15%; 603 volumes per run) images were acquired. Thirty‐two oblique transversal slices of 3.0 × 3.0 × 3.0 mm voxels, tilted 30° relative to the anterior‐posterior commissural plane, were obtained to avoid signal dropout in frontal areas (Deichmann, Gottfried, Hutton, & Turner, 2003).

All patients and controls were scanned at the Liverpool Magnetic Resonance Imaging Centre (LiMRIC) using a 3 T Siemens Prisma MR scanner. Scanning included a T1‐weighted magnetization‐prepared rapid acquisition gradient echo sequence (MPRAGE; 192 slices, repetition time [TR] = 2,000 ms, inversion time [TI] = 912 ms, echo time [TE] = 2.25 ms, resolution = 1.0 × 1.0 × 1.0 mm3, flip angle = 8°, acquisition time = 7:30 min). In order to calculate FBI and FBWM parameters, two diffusion‐weighted scans were performed: (a) an FBI sequence (TR = 4,400 ms, TE = 100 ms, 46 axial slices, resolution = 2.7 × 2.7 × 2.7 mm3, b‐values = 0, 5,000 s/mm2, 128 directions) to calculate ζ and FAA; (b) a DKI sequence that was parameter‐matched to the FBI scan (b‐values = 0, 1,000, 2000 s/mm2, 30 directions) which, along with the FBI scan, allows for the calculation of Da, MDe, De,⊥, De,II, FAE, and AWF. A standard DKI scan was also performed in order to calculate standard DTI metrics of FA and MD (TR = 3,200 ms, TE = 90 ms, 50 axial slices, resolution = 2.5 × 2.5 × 2.5 mm3, b‐values = 0, 1,000, 2,000 s/mm3, 64 directions).

Resting-state functional MRI (rs-fMRI) data were collected prior to task-based fMRI (which is not part of the present report; see previous paragraph) on a 3-T Siemens Prisma MR-Scanner equipped with a 32-channel head coil, using a multiband (MB factor = 4) EPI sequence with the following parameters: 900 volumes (10:14 min), TR = 675 ms, TE = 30 ms, voxel size = 3 mm3, flip angle = 60°, FoV = 222 mm, acquisition matrix = 74 × 74, 40 slices. During the rs-fMRI measurement, participants were asked to keep their eyes open and gaze at a white fixation cross, located at the center of a screen (Nordic Neuro Lab, 40″, 1,920 × 1,080, 60 Hz), to stay relaxed and not to think about anything specific. In a separate session, a T1 weighted (T1w) 3D structural MR scan was acquired with a MPRAGE sequence (4:26 min, voxel size = 1 mm3, TR = 1,900 ms, TE = 2.52 ms, acquisition matrix = 256 × 256, 192 slices) for purposes of coregistration between functional and structural data.

All participants underwent 18F‐florbetapir PET as well as 3.0T multimodal brain MRI. The interval between the two imaging examinations did not exceed 1 month. 18F‐florbetapir PET was scanned using Biograph 128 mCT, Siemens, Germany and uPMR790 TOF, Untied Imaging, China. Intravenous injection of 18F‐florbetapir 7.4 MBq/kg was administered according to the subject's body mass, and brain PET/CT visualization was performed after 50 min of quiet rest.10‐s low‐dose head CT scan at one bed position.20‐min brain PET scan in 3D mode; PET image reconstruction using filtered inverse projection; MR scan using a 3.0T Siemens Prisma MR scanner, Germany; T1 structural imaging using Magnetization Prepared Rapid Gradient Echo imaging (MPRAGE).
Postacquisition images were visually assessed using FBP reconstruction. Reconstructed 18F‐florbetapir PET images were visually analyzed by an intermediate (W.‐Y.W.) and a senior PET diagnostician (J.‐J.G.). In the case of disagreement, a third senior diagnostician (F.X.or C.‐T.Z.) made the judgment. Based on the distribution of cortical Aβ deposits, the diagnostic results were categorized as positive and negative (Figure S2).

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.
