Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis

Figure 4 Percutaneous computed tomography-guided core needle biopsy of a pancreatic lesion using transhepatic access. A: Contrast-enhanced computed tomography showing an expansive lesion in the head and body of the pancreas (arrows). As the patient could not stay in the prone position, the posterior approach was not possible. Therefore, an anterior transhepatic approach was used; B: Biopsy needle (18 G) tip placed adjacent to the pancreatic lesion through the left liver lobe.
