Early lung cancer detection method

Abstract

The invention belongs to the field of early lung cancer diagnosis and detection, and discloses an early lung cancer detection method, which comprises the following steps of S1, performing three-dimensional scanning on an airway system of a patient through a PET-CT scanner to obtain data required by three-dimensional reconstruction of the airway system and lung tissue junctions of the patient; S2,acquiring a registration matrix of an electromagnetic navigation bronchoscope according to the preoperative PET-CT image; and S3, performing navigation according to the registration matrix, and acquiring a focus image by using a peripheral ultrasonic probe. According to the early lung cancer detection method provided by the invention, early lung cancer can be diagnosed in time, disease delay is avoided, according to the scheme, under the condition that a conventional bronchoscope cannot be used for deep examination, the electromagnetic navigation bronchoscope can be used for deep diagnosis, the electromagnetic navigation bronchoscope is guided by the probe to enter the next stage of bronchus to reach pulmonary alveoli, pathological sampling is conducted through biopsy, and the peripheral lesion diagnosis rate reaches 80% or above, and the method is far higher than that of other existing diagnosis means.

Description

technical field [0001] The invention relates to the technical field of diagnosis and detection of early lung cancer, in particular to a detection method for early lung cancer. Background technique [0002] Lung cancer (carcinoma of the lungs) is one of the malignant tumors that seriously threaten human life and health. In the world, the morbidity and mortality of lung cancer rank first. [0003] Although the medical community has carried out etiological research and tumor genetics investigations on lung cancer, and has made many improvements in the diagnosis and treatment of lung cancer, the mortality rate of lung cancer has risen rapidly in the past few decades, while the overall survival rate has remained low. Very low, the 5-year survival rate of lung cancer in my country is only 16.1%, and the 5-year survival rate of lung cancer worldwide is only 18.1%. It has already reached the advanced stage, the tumor has metastasized, the cure rate of lung cancer is low, and the mort...
