3.0 t whole body mr system

Manufactured by Philips

The 3.0 T whole body MR system is a magnetic resonance imaging (MRI) scanner that operates at a static magnetic field strength of 3.0 Tesla. It is designed to capture high-resolution images of the entire human body. The system's core function is to generate detailed anatomical and functional information about the body's internal structures and processes through the use of strong magnetic fields and radio waves.

The MRI examination was performed using a 3.0 T whole body MR system (Philips Medical Systems, Best, the Netherlands). Anatomical images were acquired with a T1-weighted sequence: repetition time (TR) = 8 ms, echo time (TE) = 3.7 ms, Flip Angle (FA) = 8°, field of view (FOV) = 240×240 mm², voxel size = 1 mm isotropic, matrix size = 240×240, and number of slices = 180.
The resting state scans were performed using a T2* echo planar imaging sequence: TR = 2000 ms, TE = 35 ms, FA = 90°, FOV = 224×224 mm², voxel size = 3.5 mm isotropic, matrix size = 64×64, and number of slices = 36 (scan time 7 min). A high-resolution T2* echo planar imaging sequence was collected to improve registration: TR = 2200 ms, TE = 30 ms, FA = 80°, FOV = 224×224 mm², voxel size = 2 mm isotropic, matrix size = 112×110, and number of slices = 70. Participants were instructed to stay relaxed, keep eyes open, and to fixate on a white cross that was projected on a mirror mounted on the head coil.

Gadoxetic Acid vs. Gadopentetate Dimeglumine MRI Protocols

Check if the same lab product or an alternative is used in the 5 most similar protocols

Sixty-eight patients underwent gadoxetic acid-enhanced MRI (Gd-EOB-MRI) and 82 patients underwent gadopentetate dimeglumine-enhanced (Gd-DTPA) MRI. MR images were obtained using a 3.0-T whole-body MR system (Achieva; Philips Healthcare) with a 16-channel phased-array coil. Scanning sequences included a dual gradient-recalled echo T1-weighted sequence, an axial T2-weighted fat-suppression (FS) turbo spin-echo (TSE) sequence, dynamic contrast-enhanced MRI-Gd-EOB-MRI (unenhanced, arterial [20–35 s], portal [60 s], transitional phase [3 min], and hepatobiliary phase [20 min]) or Gd-DTPA-MRI (unenhanced, arterial [20–35 s], portal [60 s], and equilibrium [3 min]), and DW imaging with b-values of 0 and 800 s/mm². Apparent diffusion coefficient (ADC) maps were created automatically on a voxel-by-voxel basis from the two b-values. The detailed MRI parameters are summarized in Table 1.Table 1

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.
