Abstract :

<p>&nbsp;Introduction: Computed tomography (CT) guided biopsies of lung masses have been in use since long to take</p> <div>biopsy of lung masses. That has been proved as standard technique to get histopathological diagnosis of</div> <div>underlying mass lesion.</div> <div>Ultrasound guided biopsy of pleural based peripherally situated mass lesion is nowadays popular method and has advantage of real time</div> <div>technique with fast and radiation free technique and can be done in ultrasound room or bed side. In this study we aim to do comparative</div> <div>study of USG and CT guided biopsy in peripheral lung masses.</div> <div>Methods and Material: A study of 50 cases was carried out in department of Radio-diagnosis at GCS Medical College, Hospital and</div> <div>Research center and record of both methods were kept for comparison. Biopsies were done on CT table in CT scan room under CT / USG</div> <div>guidance with standby anesthetic and patient kept for observation in recovery room.</div> <div>Results: Out of 50 patients, 30 patients in which mass was seen under USG and no lung parenchyma was seen in between mass and pleura</div> <div>were done using USG guidance. Needle insertion was done under USG guidance and then con􀃶rmed on CT scan. In 20 patients CT guidance</div> <div>was used as lesion was not visualized on USG.</div> <div>Conclusions: For pleural based large lesions (lesion greater than 3 cm), ultrasound guided biopsy is modality of choice as ease of procedure</div> <div>with real time approach, low rate of complications, lower time consuming and radiation free technique while CT is ideal for small lesion</div> <div>which cannot be seen on USG, intra parenchymal deeply situated lesion and lesion behind rib.</div>
