AB 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  (MR)  imaging  (MRI),  MR  angiography  (MRA),  functional  MRI  (fMRI),  MR  spectroscopy  (MRS),  MR  neurography  (MRN),  diffusion  and  diffusion  tensor  imaging,  susceptibility-weighted  MR  imaging  (SWI),  arterial  spin  label  MRI  (ASL)  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.  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  4-1).
