On chest CT, lung nodules that appear “ground glass” (GG) or “subsolid” have a higher risk of malignancy than an incidentally detected solid nodule and 75% of subsolid nodules (SSN) are adenocarcinomas4. The current Fleischner guidelines recommend that SSN with solid component ≥6 mm ...
HRCT、PET/CT及PET/CT联合HRCT对肺磨玻璃结节诊断的灵敏度分别为75.0%、82.5%、90.0%,特异度分别为81.3%、78.1%、68.8%,准确率分别为77.8%、80.6%、80.6%。 结论 18F-FDG PET/CT联合HRCT通过对肺磨玻璃结节的代谢情况及影像学分析,对其鉴别诊断有一定的临床价值,两者联合使用可以提高诊断的灵敏度。 关键词:...
Conventional CT is more sensitive and specific than plain chest radiography in the diagnosis of both parenchymal and pleural diseases related to asbestos exposure. CT remains the main imaging modality used in the initial evaluation of patients with suspected MPM. Improvement in the proficiency of ...
Additionally, it has also been used in image reconstruction3 and it is reported that image reconstruction using deep learning improves the image quality of computed tomography (CT), such as coronary artery or abdominal ultra-high-resolution CT (U-HRCT) images3,4. Several investigations have ...
[Key words] low-dose;CT;chest diseases 前言 随着CT设备软硬件技术水平的不断提高,CT在各级医疗机构中广泛普及以及广大医务工作者和患者对CT在疾病诊断中作用的认可,使得受检人群接受CT检查的辐射总剂量在不断增加。据有关研究证实,医用低剂量电离辐射(0～100mSv)也会对身体健康造成威胁,可增加罹患放射相关疾病...
ResultsThere were statistically significant differences in age, pGGN morphology, lobulation, vacuolar sign, bronchial abnormality sign, internal vascular sign, pleural traction sign, longest diameter, shortest diameter, unenhanced CT value, contrast-enhanced CT value in arterial phase, contrast-enhanced ...
Thoracic High Resolution Computed Tomography (HRCT) has been clearly demonstrated to be more sensitive and specific than Chest X-Rays for the diagnosis of asbestos-related diseases even at early stages [3] and for lung cancer [4]. The question of CT scan screening for lung cancer is currently...
