AB The  diagnosis  of  diseases  of  the  liver,  biliary  tract,  and  pancreas  optimally  depends  on  using  both  clinical  and  radiographic  data.  Understanding  the  proper  use  of  these  data  and  ordering  radiographic  studies  in  the  optimal  sequence  are  helpful  for  making  the  diagnosis  most  efficiently.  Frequently,  the  clinical  presentation  and  associated  laboratory  work  provide  most  of  the  clues  for  diagnosis.  Physical  examination,  history,  and  pertinent  laboratory  values  are  often  helpful  in  making  the  diagnosis  or  at  least  in  providing  clues  for  selecting  the  optimal  radiographic  studies.  If  clinical  information  is  insufficient  or  if  radiographic  confirmation  is  necessary,  plain  films  and  contrast  studies  may  be  performed.  Upright  and  supine  plain  radiographs  are  helpful  for  the  detection  of  free  air,  calcifications,  and  other  abnormalities.  Contrast  studies  such  as  endoscopic  retrograde  cholangiopancreatography  (ERCP),  magnetic  resonance  cholangiopancreatography  (MRCP)  and  percutaneous  transhepatic  cholangiography  (PTC)  are  often  helpful  in  analyzing  diseases  of  the  liver,  biliary  tree,  and  pancreas.  For  instance,  pancreatic  or  biliary  ductal  systems,  fistulae  from  these  ductal  systems,  and  associated  abnormalities  such  as  encasing  tumors  can  be  diagnosed  by  cholangiography.
