DW-MRI images were acquired using Achieva 1.5 T system (Philips Medical system, Eindhoven, Netherlands)—5 patients—or a Magnetom Avanto 1.5 T system (Siemens Medical Solutions, Erlangen, Germany)—13 patients—both with a body-matrix coil and spine array coil for signal reception. The data were acquired axially by means of echo planar imaging. The sequences’ parameters (for both equipment) are reported in Table 1 . Diffusion-weighted images (DWI) were acquired using four b values (50, 400, 800, and 1000 s/mm2).

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.
