The Guidelines of Laser on Lung Biopsy under CT Guidance


The purpose of this study was to evaluate the usefulness of laser guidance to target tissue within the lung, while applying Percutaneous CT-guided Needle Biopsy(PCNB) using two lasers. 64 MDCT(Multi Detector Computed Tomography), Chest phantom which was inserted with tissue in Bolus, 20 Gauge needle for biopsy, Two Lasers were used. When the needle puncture chest phantom, Two Lasers which were installed above head and next to side of the chest phantom guide the needle. Using the laser before and after was compared using a needle of biopsy. Each experiment was repeated ten times. As using laser, the average number of puncture was decreased from 2.2 times (before)to 1.4 times (after). It was decreased about 34%. Time of biopsy was decrease about 25%. DLP (Dose Length Product) was decrease about 17 %. PCNB by using two lasers can accurately do targeting tissue within the lung.
