[Clinical imaging of osteo-condensed metastases].
BACKGROUND
Due to the occurrence of osteoblastic metastases in the course of various cancers, particularly in the course of prostate cancer, we are faced with diagnosis and follow-up issues different from those associated with lytic metastasis. We therefore analyzed the respective advantages of imaging techniques.


BACKGROUND
Most of the time, osteoblastic metastases are evidenced by standard radiography. Due to its ability to demonstrate metastases localization, extent and signs, CT scan is not only of value when osteoblastic metastases are suspected but also for patient's follow-up. MRI provides further information in regard to both the lesion content and osteoblastic degree. Though MRI must be performed after all other imaging procedures, it is of value for multiplanar study of the whole spine.


CONCLUSIONS
Studies focusing on either the lesion content and volume or helical CT are in progress and aim at better monitoring follow-up, while the objective of dynamic MRI studies is to better analyze lesion content.
