Advances in interventional neuroimaging.

Advances in neuroimaging have aided in the development of useful diagnostic modalities for neurological disease and have helped improve existing therapies and pioneer newer therapies in the field of interventional neurology, a new subspecialty of neurology. In this chapter, the authors discuss the advances in various neuroimaging modalities, such as digital subtraction angiography, transcranial and intravascular ultrasonography, interventional dynamic computed tomography and 64-slice computed tomographic scanners, magnetic resonance image-guided interventions and intravascular magnetic resonance imaging, and molecular and cellular neuroimaging tools using microbubbles. The authors also summarize the clinical usefulness of these advances and their role in improving the diagnostic and therapeutic potential of neurointerventional procedures.
