Magnetic resonance imaging (MRI images were acquired within 72 h of stroke onset on a 3.0 T Magnetom Verio Syngo instrument (Siemens, Munich, Germany). The radiologist used diagnostic workstations with a unisight system for interpretation and measurement of the infarct volume. The analysis was performed blind to the clinical history, physical findings, patient identity, and final diagnostic results. The total infarct volume was calculated on the basis of the infarct size on the diffusion-weighted imaging sequence and then multiplied by the thickness. All image data were standardized according to intracranial cross-sectional area18 (link). The formula of the volume standardization of cerebral infarction was as follows: infarct volume × mean of intracranial cross-sectional area/intracranial cross-sectional area of patient.
Magnetom verio syngo
The Magnetom Verio Syngo is a magnetic resonance imaging (MRI) system produced by Siemens. It is designed to provide high-quality medical imaging for diagnostic and research purposes. The Magnetom Verio Syngo utilizes a 3 Tesla superconducting magnet and advanced imaging technologies to capture detailed images of the body's internal structures.

Multimodal MRI Neuroimaging Protocol
MRI data from a separate cohort of TBI patients and healthy control subjects, were acquired using a 3 T Siemens Magnetom Verio Syngo with a 32-channel head coil. Standard clinical MRI was collected. Resting-state functional MRI data were also acquired, alongside a high-resolution T1-weighted image and DTI (see
Standardized Cerebral Infarct Volume Measurement
fMRI Study of Pain Perception
Before functional data were acquired, anatomical images were obtained using a T1-weighted magnetization prepared rapid acquisition gradient echo (MPRAGE) sequence: (TR/TE/TI=2 500 ms/2.48 ms/900 ms, flip angle = 8°, FOV = 256 × 256 mm2, voxel size = 1 mm × 1 mm × 1 mm, 192 slices, no gap).
Each participant was asked to evaluate the maximal pain during the task and the degree of residual discomfort after MR examination using the VAS.

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.
