FDG-PET/CT对于T1期肺癌N期与M期病灶诊断优于普通CT,但受CT衰减校正 (CT attenuation-corrected, CTAC)数据采集与重建模式影响与早期肺癌糖代谢低的特点,T1期(直径≤3 cm,实性、部分实性、非实性)原发灶检出与定性比较困难。肺部低剂量CT(low dose CT, LDCT)可以弥补前者缺点。通过改进数据采集重建模式,使...
If you are a smoker or a former smoker, a simple screening could save your life. Take our online Lung Health Assessment.
Preparation for a Low-Dose CT Scan There is no preparation required for a low-dose lung screening, so you can eat and drink normally before the test. Wear clothing that is easy to take off and put on, and leave all jewelry at home. What Should I Expect From a Low-Dose Lung Screening?
CT screening for lung cancer brings forward early disease. The randomised Danish Lung Cancer Screening Trial: status after five annual screening rounds wit... BACKGROUND: The effects of low-dose CT screening on disease stage shift, mortality and overdiagnosis are unclear. Lung cancer findings and ...
Low radiation dose computed tomography (CT) has been shown to have a much higher sensitivity for small pulmonary nodules, which are believed to be the most common presentation of early lung cancer. As, however, small pulmonary nodules are common and most are not malignant, non-invasive ...
Lung Cancer Screening With Low-Dose CT: Its Effect on Smoking Behavior Lung cancer screening provides an opportunity for smoking cessation interventions. A review of the literature found that smokers who participated in lung cancer screening had a higher smoking cessation rate compared with smokers in...
