Electromagnetic navigational percutaneous transthoracic needle lung biopsy for peripheral small lung nodules not amenable to navigational bronchoscopy

: Lung cancer is one of the most common causes death in US. Screening for lung has therefore become imperative as early detection shown to improve survival. Low dose computed tomography (CT) imaging chest an important tool help identify nodules screened population. Once a nodule identified, there are several ways obtain diagnosis, with technique dependent on location and size nodule. About 500,000 bronchoscopies performed annually US goal diagnosis but 65% these fails reach peripheral lesions. This results diagnostic yield around 14% lesions less than 2 cm size. lower that CT-guided biopsy. A variety new technologies tools have been developed bronchoscopic tissue solitary pulmonary (SPN), continue limited success setting small nodules. review will focus electromagnetic navigational (EMN) guided percutaneous transthoracic biopsy not amenable bronchoscopy by non-interventional radiology providers.
