Evaluation of Clinical Significance and Feasibility of CT Guided Biopsy of Double Site Lesions：A Preliminary Lung Centered Study

CT guided biopsy is minimally invasive, accurate and low cost. It is often used as an important diagnostic method when the clinical suspect of malignant disease or the treatment effect of the disease is not good. In patients with suspected malignant lung disease, metastasis of other parts of lung, pulmonary door, mediastinum, bone, and distant soft tissue may be combined at the same time. It is the key link of clinical work to evaluate the nature of these coexisting lesions accurately and choose appropriate treatment methods. At present, there is little clinical study on lung centered double site biopsy. This study aims to explore the clinical significance and feasibility of double site biopsy by analyzing the pathological characteristics and the incidence of main complications of CT guided puncture biopsy of lung and other parts coexisting lesions.
