Measurement of tissue impedence in conjunction with computed tomography-guided stereotaxic biopsies.
  1. D E Bullard,
  2. T T Makachinas


    Twenty-two patients undergoing CT-guided stereotaxic biopsies had intraoperative monopolar and bipolar impedance monitoring along the trajectory of the biopsy. Patterns of tissue impedance were retrospectively correlated with CT scans demonstrating decreased impedance generally corresponding to low density regions and increased impedance to the enhancing lesions.
