Brief Summary:

The purpose of the trial is to evaluate the differences between PercuNav assisted and unassisted biopsy in the areas of CT radiation dose, procedure time and biopsy accuracy.

This prospective, randomized, controlled trial will compare the use of electromagnetic tracking and image guidance (CT) during biopsy procedures verses the typical CT image guided procedure alone.

Unassisted Biopsy - CONTROL GROUP
Routine biopsy needle placement and Physician blinded to needle location
Assisted Biopsy - STUDY GROUP
The physician will be shown the PercuNav screen and will correct the desired approach path.

Primary Outcome Measures :
  1. Radiation Dose [ Time Frame: 24 hrs ]
    The primary objective of this study is to assess and quantify any differences between assisted and unassisted CT guided biopsy procedures of the liver with respect to radiation dose.

Secondary Outcome Measures :
  1. Total procedure time [ Time Frame: 24 hrs ]
    Total procedure time is determined by the timespan of the moment the patient is accepted into the room (start) and the time when the procedure is complete (finish - when physician exits room).

  2. Accuracy of needle targeting [ Time Frame: 24 hrs ]
    Distance from defined target on PercuNav and angle of entry
