Publikováno v: American Journal of Roentgenology. 191:W275-W282

We used an algorithm for quantitative image processing to classify breast tissue into the categories fibrosis, involution atrophy, and normal. The algorithm entailed use of Minkowski functionals in topologic analysis of x-ray attenuation patterns on

Using Radon transform of standard radiographs of the hip to differentiate between post-menopausal women with and without fracture of the proximal femur

Publikováno v: Osteoporosis International. 20:323-333

Texture features based on the Radon transform were extracted from clinical radiographs of the hip in post-menopausal women. The novel algorithm allowed us to identify patients with fracture of the proximal femur and may provide an alternative to meas

The 3D-based scaling index algorithm: a new structure measure to analyze trabecular bone architecture in high-resolution MR images in vivo

Autor: Roberto A. Monetti, Thomas M. Link, Holger F. Boehm, Ernst J. Rummeny, Jan S. Bauer, Vanadin Seifert-Klauss, Dirk Mueller, Christoph W. Raeth, Gregor E. Morfill

Publikováno v: Osteoporosis International. 17:1483-1493

The purpose of this study was to obtain different structure measures as the three-dimensional (3D)-based scaling index method (SIM) and standard two-dimensional (2D) bone histomorphometric parameters from high-resolution (HR) magnetic resonance (MR)

Publikováno v: Journal of Clinical Densitometry. 8:488-494

We tested the hypothesis that bone mineral density (BMD) and bone mineral content (BMC) in proximal human femur specimens in the upper neck region of interest (ROI) and femoral neck axis length (FNAL) provide a significantly better prediction of femo

Bone imaging: Traditional techniques and their interpretation

Autor: Thomas M. Link, Holger F. Boehm

Publikováno v: Current Osteoporosis Reports. 2:41-46

Patients with osteoporosis have to be diagnosed at an early stage to prevent fractures, the worst complication of this disease. Currently, measurements of bone mineral density (BMD) are used most frequently in the diagnosis of osteoporosis. According

Publikováno v: Journal of Bone and Mineral Research. 19:379-385

In this experimental study, we evaluated the reproducibility error of mechanical strength tests of the proximal femur when simulating a fall on the trochanter. Based on side differences in femoral failure loads in 55 pairs of femora, we estimated the
