Imaging of the skeleton

Methods of examination: plain x-ray (radiography, densitometry) x-ray with contrast material (fistulography, angiography) ultrasound (b-mode, Doppler, color, duplex) computed tomography magnetic resonance imaging x-ray-, US-, CT-guided intervention isotope Department of Radiology, University of Szeged

Primary bone changes: change of shape (deformity) change of structure (heteroplasia) change of calcium content increased (osteosclerosis) decreased (atrophy, porosis, malacia) bone necrosis (osteonecrosis) bone destruction (osteolysis) Department of Radiology, University of Szeged
