Techniques like diffusion-weighted imaging (DWI) are critical for early stroke detection, while spectroscopy and perfusion imaging provide metabolic and functional insights. Key Clinical Areas of Focus
Neuroradiology: The Essentials with MR and CT Neuroradiology is a specialized field of medical imaging focused on diagnosing disorders of the brain, spine, and head and neck. Central to this discipline is the strategic use of and Magnetic Resonance Imaging (MRI) , which provide the high-resolution visualization necessary for modern neurological care.

Uses ionizing radiation to create cross-sectional images based on tissue attenuation, measured in Hounsfield units (HU). It is highly sensitive for white matter diseases
Offers superior soft-tissue contrast resolution, making it the preferred choice for detailed analysis of tumors, inflammation, and chronic conditions. It is highly sensitive for white matter diseases like multiple sclerosis.
Employs powerful magnetic fields and radiofrequency pulses to capture signals from water and organic molecules.
CT angiography (CTA) is frequently used to assess vascular issues like aneurysms and acute stroke. Magnetic Resonance Imaging (MRI):
