Lumbar MRI Imaging Protocol for Spinal Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
All patients underwent lumbar MRI scans with a Magnetom Trio 3.0T MRI scanner (Siemens, Germany). All patients were in the supine position. Scan parameters were pulse repetition time of 575 ms, echo time of 18.5 ms, field of view of 160 mm × 160 mm, voxel size of 0.4 mm × 0.4 mm × 4.0 mm, and layer spacing of 0.3 mm.
The imaging data were exported from the hospital’s PACS system, and the patients’ lumbar MRI images (including sagittal T1, T2 sequences, and transverse T2 scans) were collected. The imaging features data were collected by observing the image pictures to highlight the most severe segments and the ITK-SNAP software [21 (link)] was used to measure the highlighted segments in the image pictures.

The images were acquired using standard sequences with a Siemens Magnetom Trio 3.0 T MRI scanner (Siemens, Erlangen, Germany) equipped with an eight-channel head coil at the Magnetic Resonance Center of Hunan Provincial People’s Hospital, China.
Three-dimensional T1-weighted structural brain images were acquired with a gradient echo sequence: repetition time = 2,000 ms, echo time = 2.26 ms, field of view = 256 × 256 mm, flip angle = 8°, matrix size = 256 × 256, number of slices = 176, slice thickness = 1 mm.
The functional images were collected using an echo-planar imaging sequence with the following parameters: number of slice = 32, repetition time = 2,000 ms, echo time = 30 ms, slice thickness = 4.00 mm, flip angle = 90°, matrix = 64 × 64, field of view = 220 × 220 mm2.

Brain Activation Induced by Erotic Stimuli

Check if the same lab product or an alternative is used in the 5 most similar protocols
The fMRI and T1-weighted images were acquired using a MAGNETOM Trio 3.0T MRI Scanner (Siemens Healthineers; Munich, Germany) and a standard birdcage-type head coil. To induce images of brain activation, the erotic videos were projected through a semitransparent screen to facilitate viewing through a mirror. The fMRI pulse sequence was gradient-echo echo-planar imaging with the following characteristics: repetition time/time to echo (2000/30 msec), field of view (22 cm × 22 cm), matrix (64 × 64), number of slices (30), slice thickness (5 mm), flip angle (90°0), and slice interval (0 mm). Each slice image was acquired from the axial plane parallel to the anterior commissure-posterior commissure line. The pulse sequence of the T1-weighted images was based on a multiplanar rapidly acquired gradient echo with the following characteristics: repetition time/time to echo (1900/2.35 msec), matrix (256 × 256), and field of view (22 cm × 22 cm).

which is the first all-around, broad-scale, multi-focus, observational, international study to identify PD progression biomarkers [14 ]. MRI and DTI data are collected by the Siemens MAGNETOM Trio 3.0 T MRI scanner. For MRI images, the selection criteria are as follows: acquisition plane = SAGITTAL, pulse sequence = GR/IR, field strength = 3, slice thickness = 1, flip angle = 9, TE = 2.98, and TR = 2300. We select the DTI images using the following parameters: pulse sequence = EP, gradient directions = 64, processed data label = FA map-MRI, field strength = 3, slice thickness = 2, flip angle = 90, TE = 88, and TR = 600–1000.

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.
