Central Nervous System

Intrinsic Imaging radiologists are deeply involved in the diagnosis and treatment of central nervous system disorders and review approximately 400,000 CNS images annually.

Our team of 7 full time time fellowship trained CAQ board certified neuroradiologists specializes in all brain and spine pathology with broad experience and expertise in MRI, CT, diagnostic and interventional angiographic procedures, as well as PET imaging using novel CNS markers.

Clinical trials involving disorders of the Central Nervous System (CNS) present a number of challenges. A wealth of domain knowledge utilizing validated scoring methods in centralized image processing and analysis for all necessary modalities and techniques is required.

At Intrinsic Imaging, we are dedicated to the treatment of Central Nervous System disorders. Our expertise includes, but is not limited to;

• Tumors with novel measurement techniques
• Alzheimer's and variants
• Parkinson’s including dyskinesias
• Spinal degenerative diseases with spinal cord injury
• Demyelinating inflammatory diseases Multiple Sclerosis and polyneuropathies
• Aneurysm and vascular malformations
• Neurointerventional Devices

Further, Intrinsic Imaging neuroradiology expertise includes, but is not limited to;

• Expertise including but not limited to the full complement of brain and spine disease processes with special emphasis on vascular diseases.
  
  
• Multiple modality expertise including: ultrasound, nuclear imaging, PET, invasive angiography, MR, and CT including novel techniques such as functional MRI, MTR, and perfusion.
  
  
• Expertise in adults and pediatrics.
  
  
• Extensive expertise in the interpretation of complex trauma imaging in TBI.
  
  
• Stroke evaluation and treatment including diffusion and perfusion imaging with subsequent intravenous and intra-arterial thrombectomy and thrombolysis.
  
  
• Ultrasound, CTA, MRA and catheter angiography for quantifying percent stenosis of the carotid bifurcation by the NASCET criteria.
  
  
• Alzheimer’s disease analysis with quantitative PET, CT and evaluation using sub-segmentation of the cerebralcortex including gray and white matter volumes as well as hippocampal volumes.
  
  
• Evaluation and treatment of cerebral aneurysms, arteriovenous malformations (AVM’s) and dural arteriovenous fistulas (DAVF’s) with CTA, MRA and catheter angiography
  
  
• Preoperative imaging with functional MRI (fMRI), diffusion tensor imaging (DTI), perfusion, spectroscopy and surface rendering of the cortex and cortical venous anatomy.
  
  
• Quantitative CSF flow analysis for Normal Pressure Hydrocephalus (communicating hydrocephalus) and obstructive hydrocephalus.
  
  
• Subspecialty interpretation of CT and MRI of spinal degenerative disease.
