TL;DR: The algorithm showed excellent performance in detecting COVID-19 pneumonia on chest CT images compared with resident radiologists, and the higher sensitivity of deep learning model in detectingCOVID- 19 pneumonia were found compared with radiological residents on a per-lobe and per-patient basis.

TL;DR: The risk factors of older age, multiple comorbidities, leukocytosis, lymphopenia and higher CT severity score could help clinicians identify patients with potential adverse events.

TL;DR: Prospectively ECG-triggered high-pitch CCTA at 70 kVp with 30 mL of contrast agent can provide diagnostic image quality at a radiation dose of less than 0.2 mSv in patients with a body mass index less than 25 kg/m2 and an HR ofLess than 70 bpm, suitable for normal-weight patients with slow heart rate.

TL;DR: Prospectively ECG-triggered high-pitch CCTA at 70 kVp is feasible and has a high diagnostic accuracy for stenosis detection in a selected, non-obese population, compared to invasive coronary angiography as reference standard.

TL;DR: Cerebral CTA at 100 or 80 kVp using 30 ml contrast agent can obtain diagnostic image quality with a low radiation dose while maintaining the same diagnostic accuracy for aneurysm detection.
