Some of the indications for performing a chest CT scan with contrast include the following; If cancer is suspected in the lungs on the chest X-ray The suspected parenchymal disease of the lungs Lung infections (COVID-19) or abscesses Suspicion of a tumor/cancer in any of the chest organ ...
EP07.01-07 Comparison of Surveillance with Contrast Chest CT and Non-contrast Chest CT among who Survived 2 Years after Curative Resection for Lung Cancer B Na,JH Park,T Yun,... - 《Journal of Thoracic Oncology》 被引量: 0发表: 2023年 Comprehensive analyses with radiological and biological ...
CTI identified any chest injury in 54 per cent of patients compared with 46 per cent with CTA (P = 0.05). The rate of BAI was similar with CTI and CTA (2% vs 2%, P = 0.80), and neither modality was falsely negative. We conclude that CTI and CTA are similar at evaluating trauma ...
Axial contrast-enhanced chest CT shows the mediastinal mass (arrows) composed of enlarged prevascular and right paratracheal lymph nodes. Lymphoma is the most common anterior mediastinal mass in a ...
If contrast enhanced chest CT scan has a significant agreement with biochemical tests, it can be considered as a non invasive reliable method for evaluation of pleural effusion. quot;nPatients and Methods: We evaluated 32 patients who had pleural effusion from June 2005 to June 2006 in 22nd ...
How Low Can We Go in Contrast-Enhanced CT Imaging of the Chest?: A Dose-Finding Cadaver Study Using the Model-based Iterative Image Reconstruction Approach How low can we go in contrast-enhanced CT imaging of the chest? A dose-finding cadaver study using the model-based iterative image ...

For a segmentation task, when dealing with highly imbalanced datasets, which is common when dealing with COVID-19 chest CT images, equally penalizing False Negatives (FNs) and False Positives (FPs) during the training process will result in a low sensitivity in predicted masks. To tackle this ...
The article presents a feasibility study of non-electrocardiography (ECG)-gated low peak kilovoltage (kVp) scan of the whole chest after coronary computed tomography (CT) angiography. It highlights the accuracy of coronary CT in coronary artery disease evaluation. An overview on the comparison betwe...
We show in a proof-of-concept that a CNN-based federated deep learning model can be used for accurately detecting chest CT abnormalities in COVID-19 patients. Importantly, the AI model trained on Hong Kong cohorts showed high performance not only on internal testing cases, but also on externa...
