Review on Image Guided Lung Biopsy

Abstract

Lung biopsy is an established field. Throughout years physician andscientist have been exploring the field, from technical and clinicalpoint of view. Mainly there are three types of lung biopsy, open,bronchoscopic, and fine needle aspiration biopsy. Open biopsy isessentially a surgery, thus not really dependent on image guidingsystem. On the other hand, bronchoscopic and fine needle aspirationbiopsy relay heavily in image guiding system. Curiously, it is rare tofind both biopsy types talked side by side. In this paper, both biopsytypes explored and compared from technical and clinical point of view.Technical wise, bronchoscopic biopsy trend is toward path findingalgorithm, while fine needle aspiration biopsy trend is toward breathingcompensation algorithm and automatization. Clinical wise, there is noevidence that one type hold better diagnostic value than the other.
