Embodiment 1
[0047] A method for identifying early-stage lung adenocarcinomas presenting as ground-glass nodules such as figure 1 shown, including the following steps:
[0048] Step 1: Medical History Collection
[0049] Firstly, the patients who were pre-examined by PET / CT due to ground-glass nodules were interviewed, and the medical history data were collected, including: patient age, gender, smoking history, recent peripheral blood tumor markers, tumor history, whether accompanied by severe liver disease or diabetes Diseases that may affect PET / CT semi-quantitative indicators, the blood tumor markers include CEA, CYFRA21-1, CA199, NSE, SCCAg;
[0050] Step 2: Image Acquisition
[0051] Image scanning was performed using a PET / CT imager of Siemens Biograph mCT 64, imaging agent 18F-FDG, radiochemical purity > 95%, fasting > 4 hours, blood glucose ≤ 10mmol / L, intravenous injection of 18F- FDG, and the dose of 18F-FDG is 3.70-7.77MBq / kg, whole body PET / CT imaging will be performed 1h la...
