QCT of the proximal femur—which parameters should be measured to discriminate hip fracture?
For quantitative computed tomography (QCT), most relevant variables to discriminate hip fractures were determined. A multivariate analysis showed that trabecular bone mineral density (BMD) of the trochanter wi...

Imagerie des métastases osseuses
L’os représente le troisième site métastatique après le foie et le poumon. Les métastases osseuses (MO) se localisent préférentiellement dans les zones de moelle rouge. Sur le rachis, les métastases osseuses s...

CT imaging for the investigation of subchondral bone in knee osteoarthritis
In osteoarthritis, magnetic resonance imaging is the method of choice to image articular cartilage and “bone marrow lesions.” However, the calcified cartilage, the subchondral bone plate, and trabecular subcho...

The lucent rim: a radiographic and computed tomography sign of Paget's disease of the skull
In seven of eight patients with osteoporosis circumscripta of the cranial vault, the pagetic bone lacunae were separated from the normal bone by a lucent rim visible on conventional radiographs and computed to...

Volumetric quantitative computed tomography of the proximal femur: relationships linking geometric and densitometric variables to bone strength. Role for compact bone
In assessing cervical fractures of the proximal femur, this in vitro quantitative computed tomography (QCT) study had three objectives: to compare QCT to dual-energy X-ray absorptiometry (DXA) for predicting t...

Three-dimensional X-ray absorptiometry (3D-XA): a method for reconstruction of human bones using a dual X-ray absorptiometry device
Three-dimensional accurate evaluation of the geometry of the proximal femur may be helpful for hip fracture risk evaluation. The purpose of this study was to apply and validate a stereo-radiographic 3D reconst...

Complications of percutaneous vertebroplasty and their prevention
Complications due to vertebroplasty may be divided into two categories whether or not they are related to polymethylmethacrylate (PMMA) cement leakage from the compressed vertebral body. PMMA leakage is a very...
