Question

Quizplus · Accepted Answer

Needle biopsy is a minimally invasive procedure that can be performed using various techniques, such as CT-guided or ultrasound-guided, to obtain a tissue sample from the periphery of the lung. It is a safe and efficient diagnostic tool that can provide a definitive diagnosis in about 70-90% of cases, depending on the size and location of the lesion. Scintigraphy is a nuclear medicine imaging test that can help to identify areas of abnormal cellular activity, but it is not useful for obtaining tissue samples. Mediastinoscopy and wedge resection are both invasive surgical procedures that require general anesthesia and carry a higher risk of complications, such as bleeding, infection, or pneumothorax. Bronchoscopy is another minimally invasive technique that uses a flexible camera to visualize the airways and collect samples, but it may not be able to reach lesions located in the periphery of the lung. Therefore, needle biopsy is the best choice for obtaining a tissue sample from a growth on the periphery of the lung.
