  1. Neuroradiology

  2. IMAGING TECHNIQUES • PLAIN FILMS • COMPUTED TOMOGRAPHY • MAGNETIC RESONANCE IMAGING • DIGITAL ANGIOGRAPHY • ULTRASOUND • DOPPLER US • PET

  3. Brain Imaging The basic imaging tools • Digital Substraccion Angiography (DSA) • uses a X ray tube, imaging intensifier • digital process. • Ultrasound(Doppler) Carotid, transcranial • Nuclear Medicine(SPECT, PET, PET/CT)

  4. EARLY SIGNS OF ISCHEMIC INFARCT MRI • T1 HYPOINTENSITY • T2, FLAIR HYPERINTENSITY • DWI HYPERINTENSITY • DECREASED SIGNAL IN PERFUSION IMAGES

  5. CEREBRAL VASCULAR EVENT • ISCHEMIC • HEMORRHAGIC

  6. CEREBRO VASCULAR EVENT ISCHEMIC THROMBO EMBOLIC VASCULITIS DISSECTION FIBROMUSCULAR DISPLASIA VENOUS THROMBOSIS ANOXIA

  7. EARLY SIGS OF ISCHEMIC INFARCT CT • LOSS OF DEFINITION BETWEEN GRAY AND WHITE MATTER • ILL DEFINITION OF INTERNAL CAPSULE • HYPERDENSE MIDDLE CEREBRAL ARTERY

  8. CEREBRO VASCULAR EVENT • HEMORRHAGIC HYPERTENSION ANEURYSM VASCULAR MALFORMATION TRAUMA COAGULOPATHY AMYLOIDOSIS

  9. TRAUMA • CONTUSION • DIFFUSE AXONAL INJURY • SUBDURAL HEMATOMA • EPIDURAL HEMATOMA • SUBARACHNOID HEMORRHAGE

  10. SEIZURE • CONGENITAL MALFORMATION • MESIAL SCLEROSIS • CVA • POSTTRAUMATIC

  11. INFLAMMATORY • MENINGO ENCEPHALITIS • ABCESS • TOXOPLASMOSIS

  12. NEOPLASIA • GLIOMAS • LYMPHOMA • MEDULOBLASTOMA • PINEAL TUMOR • PITUITARY ADENOMA • EXTRAAXIAL TUMORS • MENINGIOMA • SCHWANNOMA

  13. DEMYELINATING DISEASE • MULTIPLE SCLEROSIS • ADEM

  14. Differential Diagnosis for ring-enhancing lesions:MAGICAL DR M - Metastasis, MS A - Abscess G - Glioblastoma, Granuloma I - Infarct (esp. Basal ganglia) C - Contusion (rare) A - AIDS (Toxo, etc.) L - Lymphoma (in aids) D - Demyelination (active) R - Resolving hematoma, Radiation change (necrosis)
