AB Clinicians  have  a  wide  array  of  radiologic  modalities  at  their  disposal  to  aid  them  in  noninvasive  diagnosis.  Despite  the  introduction  of  highly  specialized  imaging  modalities,  radiologic  tests  such  as  chest  radiographs  and  ultrasound  continue  to  serve  a  vital  role  in  the  diagnostic  approach  to  pt  care.  At  most  institutions,  CT  is  available  on  an  emergent  basis  and  is  invaluable  for  initial  evaluation  of  pts  with  trauma,  suspected  CNS  hemorrhage,  or  ischemic  stroke.  MRI  and  related  techniques  (MR  angiography,  functional  MRI,  MR  spectroscopy)  provide  remarkable  resolution  of  many  tissues  including  the  brain,  vascular  system,  joints,  and  most  large  organs.  Radionuclide  scans  including  positron  emission  tomography  (PET)  can  provide  functional  assessment  of  organs  or  specific  regions  within  organs.  Combination  of  PET  with  MRI  or  CT  scanning  provides  highly  informative  images  of  the  location  and  configuration  of  metabolically  active  lesions,  such  as  cancers.  Increasingly,  internists  are  being  trained  in  the  use  of  ultrasound  to  assist  with  line  placement,  thyroid  nodules,  cardiac  sounds,  and  abdominal  abnormalities.
