Equipment Infrastructure at CAMRIS
1.0T pMRI, pQCT and Future Imaging Technologies
The following imaging infrastructure have been in part funded by Canadian Foundation for Innovation grants. Various measurements obtained from these imaging modalities have been validated and assessed for short term reliability.
The 1.0T pMRI GE Orthone System
Appendicular measurements of cartilage, muscle, bone and fat is possible with this MR technology. The advantage of MRI is the absence of ionizing radiation. This particular peripheral machine bears a small bore with replaceable radiofrequency (RF) coils varying in gantry size (from 50 mm to 180 mm), which can accomodate a wrist to a calf muscle. Various 3D gradient echo, spin echo, inversion recovery and fat-saturated images (T1 & T2-weighted) can be obtained.
The XCT2000 pQCT scanner
Periperhal quantitative computed tomography (pQCT) uses X-ray technology in 360 degree image captures to provide up to 200 μm in-plane pixel resolution 3D slices down to 2.3 ± 0.5 mm thickness. This equipment allows us to obtain information on bone and muscle densities and morphometry. For bone, this information is processed using specialized software packages designed by Inglis Software Incorporated to compute measures of bone strength and apparent microstructure.
