Abstract
Image-guided biopsy and drainage of collections in the abdomen and pelvis are frequently
performed in interventional radiology practices. Many options are available to facilitate
access to masses and collections in challenging locations. This review focuses on
the technique and efficacy associated with the various options available, including
out-of-plane access, patient positioning, needle techniques (i.e., blunt and curved
needle tip), adjunctive use of electromagnetic tracking devices, organ displacement,
and transorgan access.
