1 In the Investigation of Biliary and Pancreatic Conditions

2  Computerised Axial Tomography  X-ray tube that rotates around your body ◦ Whilst you lay flat on a bed  non-invasive ◦ Produces slices of the body  Provide more detail than standard X-rays  Scans take 10 – 30 minutes depending on location  Can be done with contrast to enhance images NHS Choices (2012)

3

4  Gold Standard Imaging technique  essential  Done as contrast CT unless Haemorrhage suspected  Pancreatitis  done after 72 hours ◦ Assess levels of necrosis ◦ Signs of fluid collection or abscess formation ◦ Pseudocyst development  Carcinoma  confirm the presence of lesion ◦ Determination of whether legion is operable ◦ Determine whether metastasis has occurred UCSD Radiology Dept (2009) Kumar & Clark (2012) Demos T C et al. (2002)

6 Lymphoepithelial cyst in asymptomatic 54-year-old woman. Demos T C et al. AJR 2002;179: ©2002 by American Roentgen Ray Society

7  Cholecystitis  observation of signs of inflammation ◦ Determine any complications  signs of gas or abscesses ◦ Calcification  porcelain gallbladder  Gallstones  Alternative method ◦ Opaque stones more readily detected  Exclusion of other causes of obstruction ◦ Carcinoma at the head of the pancreas  Carcinoma  observation of masses  solid/polypoid ◦ Observation of asymmetric or symmetric wall thickening Grand D et al. AJR (2004) Kumar & Clark (2012)

8 Contrast-enhanced CT scan obtained in 45-year-old man shows low-density gallstones. Grand D et al. AJR 2004;183: ©2004 by American Roentgen Ray Society

9 Contrast-enhanced CT scan obtained in 72-year-old man with emphysematous cholecystitis reveals air in gallbladder lumen and thickening of wall. Grand D et al. AJR 2004;183: ©2004 by American Roentgen Ray Society
