Percutaneous CT-guided biopsy: improved confirmation of sampling site and needle positioning using a multistep technique at CT fluoroscopy.

abstract：PURPOSE:Our goal was to examine the effects of collimation width (CW), pitch, viewing plane, and windowing on the display of in-plane vessels in maximum intensity projection (MIP). METHOD:A theoretical concept based on partial volume averaging of vessels was developed to describe the contents of voxels (densities) in ...
