Background:

Image guided thoracic interventions are the result of advancements in cross–sectional imaging. CT is the most commonly used imaging modality for thoracic interventions. These minimally invasive thoracic interventions like CT guided transthoracic lung biopsy and transthoracic fine needle aspiration cytology have become very popular for the diagnosis and management of thoracic lesions and hence more invasive procedures such as thoracoscopy, mediastinoscopy and thoracotomy can be avoided.This study is intended to benefit the practicing Radiologists to identify and thus help to quickly diagnose and take desperate immediate interceptive measures  to stop the natural progression of the disease.
