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.

Primary Outcome Measures:
  • Radiation Dose [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]
    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:
  • Total procedure time [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]
    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).

  • Accuracy of needle targeting [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]
    Distance from defined target on PercuNav and angle of entry

Enrollment: 50

Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
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.

Patients undergoing a liver biopsy procedure


Inclusion Criteria:

  1. Has had a pre-operative CT scan performed and will be undergoing a biopsy procedure of the liver;
  2. Is over the age of 18;
  3. Has the ability to understand and the willingness to sign a written informed consent form, and complies with the protocol;
  4. Has the ability to follow procedural instructions, including, but not limited to, holding their breath and remaining reasonably motionless during the procedure.

Exclusion Criteria:

  1. Was precluded from a biopsy procedure based on standard exclusions;
  2. Has an adhesive allergy (due to the application of active fiducials with adhesive backing);
  3. Has a pacemaker or automatic implantable cardiac defibrillator;
  4. Has a gross body weight above 180lbs for women and 260lbs for men;
  5. Is pregnant

A patient may be excluded after enrollment if any of the following criteria are met:

1. The patient's health and/or safety become jeopardized for any reason making it unsafe to continue; 2. Technical errors and/or difficulties; 3. Any reasonable rationale put forth by the physician or investigator 4. Lost to follow up - In-evaluable data
