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

Figure 3 Percutaneous computed tomography-guided core needle biopsy of a pancreatic lesion using pneumodissection. A: Contrast-enhanced magnetic resonance axial image showing a heterogeneous lesion in the body of the pancreas (arrow). The anterior approach was considered difficult because of the interposition of the intestine in the supine position, therefore, a posterior approach was used; B: Non-enhanced axial computed tomography in the prone position showing the pancreatic lesion (arrow) and the coaxial needle (17 G) positioned in the left pararenal space, where air was injected to displace the kidney and adjacent vessels; C: Biopsy needle (18 G) placed adjacent to the pancreatic lesion.
