Diagnostic performance of bilateral false profile radiographs in early hip osteoarthritis.

Objectives: 1. To show that the anterior hip joint space is profiled only on the contralateral false profile radiograph. 2.

[Stress fractures].

In 1892, J. Wolff, an orthopedic surgeon, stated that the internal architecture and shape of a bone were related to the direction of stresses placed upon it. Conventional radiographs and MRI can demonstrate the adaptability of bones to stresses.

Comparison of MR-arthrography and CT-arthrography in hyaline cartilage-thickness measurement in radiographically normal cadaver hips with anatomy as gold standard.

Objective: To compare magnetic resonance (MR)-arthrography and multidetector-spiral-computed-tomography (MDSCT)-arthrography in cartilage-thickness measurement, in hips without cartilage loss, with coronal anatomic slices as gold standard.

Method: Institutional review board permission to study cadavers of individuals who willed their bodies to science was obtained. Two independent observers measured femoral and acetabular cartilage thicknesses of 12 radiographically normal hips (six women, five men; age range, 52-98 years; mean age, 76.

[Elastography of the breast: a prospective study of 122 lesions].

Objective: To evaluate elastography in the characterization of breast nodules.

Material And Methods: Elastography (Hitachi, 7.5- to 13-MHz probe; Ueno classification, scores 1-3=benign, 4-5=malignant) was evaluated in 125 subclinical lesions in 114 patients.
