Sections: Neuroimaging in Neurologic Disorders: Introduction, Computed Tomography, Magnetic Resonance Imaging, Magnetic Resonance Angiography, Echo-Planar MR Imaging, Magnetic Resonance Neurography, Positron Emission Tomography (PET), Myelography, Spine Interventions, Angiography, Interventional Neuroradiology, Further Readings.
Topics Discussed: brain imaging; neuroimaging; neurologic disorders.
Excerpt:"The clinician caring for patients with neurologic symptoms is faced with myriad imaging options, including computed tomography (CT), CT angiography (CTA), perfusion CT (pCT), magnetic resonance imaging (MRI), MR angiography (MRA), functional MRI (fMRI), MR spectroscopy (MRS), MR neurography (MRN), diffusion and diffusion track imaging (DTI), susceptibility weighted MR imaging (SWI), and perfusion MRI (pMRI). In addition, an increasing number of interventional neuroradiologic techniques are available, including angiography catheter embolization, coiling, and stenting of vascular structures; and spine diagnostic and interventional techniques such as diskography, transforaminal and translaminar epidural and nerve root injections and blood patches. Recent developments such as multidetector CTA (MDCTA) and gadolinium-enhanced MRA, have narrowed the indications for conventional angiography, which is now reserved for patients in whom small-vessel detail is essential for diagnosis or for whom concurrent interventional therapy is planned (Table 368-1)...."
