[The strategy of new imaging procedures in the diagnosis of malignant bone processes].

From the comparison of conventional radiography, computed tomography and angiography the diagnostic value of each of these methods is evaluated. Conventional radiography will remain the most significant method for detecting primary skeletal tumours even if magnetic resonance imaging is considered. CT is an important additional method for the evaluation of tumour size, but is disappointing for tumour classification. Bone scintigraphy is the most sensitive method for the differentiation of solitary and multiple tumours. Angiography is not necessary, except for the planning of surgery in certain cases.
