OBJECTIVE. Following the findings of the National Lung Screening Trial, several national societies from multiple disciplines have endorsed the use of low-dose chest CT to screen for lung cancer. Online patient education materials are an important tool to disseminate information to the general public ...
通过CT肺筛查,可以发现早期恶性肿瘤,从而可以定位及早期治疗,增加存活率。 CT lung screening is a noninvasive, painless procedure that uses low-dose x-rays to screen the lungs for cancer in just 30 seconds. A CT lung screening allows the radiologist to look at different levels, or slices, of ...
Because CT scans use radiation to produce images, lung cancer screening exposes you to a low amount of radiation — about the same as what an average American gets from the sun in six months. For context, this amount is slightly higher than the radiation women are exposed to during mammogram...

什么是CT肺癌筛查? CT Lung Screening 肺部CT筛查是使用低剂量X射线筛选肺的癌症,可以在短短30秒内无创、无痛完成整个过程。CT肺筛查是使用螺线X线扫描技术扫描整个胸部,使放射科医生能够看到不同成次的肺部断层图片。这个过程在一个多层螺旋计算机断层扫描(CT)扫描仪中进...
New cohort analysis suggest updates to broaden the age and smoking-rate eligibility may have benefitted the historic disparity in low-dose CT screening practice.

Computed tomography (CT) scans:With a CT scan, cross-sectional images will be taken for a more detailed look at the lungs. These scans are more likely to show tumors than X-rays. Lung cancer screening:Screening is done when symptoms are not present and is often based on exposure history,...
1 Currently only 15% of lung cancer cases are diagnosed at stage I, and large trials have not supported the value of chest radiography or sputum cytology for screening.2 Low-dose computed tomography (CT) has emerged as a potentially useful screening method, with 55% to 85% of detected ...
