Past, present, and future of radiology of meningioma.

The evolution of the radiologic findings associated with meningiomas represents a microcosm of the evolution of diagnostic radiology that has occurred since the discovery by Röntgen of the x-ray beam in 1895 and the founding of the Radiological Society of North America in 1915. What will the next new, as yet unimagined, imaging modality contribute to our current ability to detect and diagnose these lesions? No one can forecast this, but it should prove to be both fascinating and challenging.
