The MRI equipment used included a GE 3.0T (GE Healthcare, Piscataway, NJ, USA) or GE 1.5T (GE Healthcare, Piscataway, NJ, USA) magnetic resonance apparatus and an 8- or 16-channel-phased array head and neck combined coil. Each patient was placed in a supine position with both hands on either side of the body and instructed not to swallow. The scanning range was from the upper border of the auricle to the level of the lower border of the cervical 3 vertebrae in the transverse axis, and the sagittal and coronal planes included the bilateral supraclavicular fossa. Conventional MRI sequences included transverse axial short-tau inversion recovery (STIR) and T1-weighted imaging(T1WI), coronal T2-weighted imaging (T2WI), sagittal T1WI, and T1WI-enhanced scan sequences (including transverse axial, coronal, and sagittal images). The IVIM-DWI sequence made 3 sets of data for each patient according to the different b values. The b1 values were 0, 10, 30, 50, 100, 150, 200, 600, and 1000(s/mm²). The b2 values were0, 50, 100, 150, 200, 600, 800, 1000, and 1200 (s/mm²). The b3 values were0, 10, 20, 30, 50, 100, 200, 600, and 1000 (s/mm²). The contrast agent was Gadolinium diethylene triamine pentaacetic acid (Gd‑DTPA) at a dose of 0.1 mmol/kg.

Trabecular bone architecture at the distal femur and cortical bone architecture and muscle volume at the level of the middle-third of the femur on the non-dominant side were estimated using MRI (GE 1.5 T; Milwaukee, WI). Children were immobilized from the waist down using the BodyFIX (Medical Intelligence, Inc., Schwabm nchen, GER), as previously described [16 (link)]. Different imaging protocols were used to collect images needed for the assessment of trabecular bone architecture and cortical bone architecture.

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.
