CT-guided lung needle biopsy

CT-guided lung biopsy is a common method for diagnosing lung diseases, with many clinical applications and a wide range of applications. CT cross-sectional scan has good spatial resolution and density resolution, and can accurately display the size, location, internal situation, and anatomical relationship of the surrounding structures of the blood vessels. , When the mass is mixed with atelectasis and obstructive pneumonia, enhanced scanning is sometimes required to determine the actual size of the mass.

CT-guided puncture is more accurate, and puncture can also be performed under CT-guided puncture for lesions of 0.5 to 1 cm. Therefore, for pulmonary nodular lesions, cavitary lesions, diffuse bilateral lung lesions and mediastinal lung that cannot be diagnosed by conventional methods For hilar space-occupying lesions, CT-guided lung aspiration and cutting needle biopsy can be used to obtain pathological tissue, especially for pulmonary nodules with a diameter of less than 2 cm, the biopsy accuracy is high, and can be used as solitary small nodules in the lung Preferred method of diagnosis.
