Clinical Scorecard: Examining Trends in Multicentric Chest Imaging via CT Before, During, and After the COVID-19 Pandemic
At a Glance
Category
Detail
Condition
COVID-19-related chest conditions including pneumonia
Key Mechanisms
CT imaging detects characteristic chest abnormalities such as ground-glass opacities and consolidation; used for diagnosis, monitoring disease progression, and treatment assessment
Target Population
Patients undergoing chest CT imaging across multiple hospitals, including asymptomatic and symptomatic COVID-19 patients
Care Setting
Hospital radiology departments utilizing CT scanners across 10 hospitals
Key Highlights
Significant increase (50%) in chest CT examinations during the COVID-19 pandemic with a 58.8% increase in all CT exams from 2019 to 2024.
Chest CT examinations plateaued post-pandemic with stable but elevated examination numbers compared to pre-pandemic levels.
Patient radiation exposure remained stable or decreased due to dose management and protocol optimization despite increased CT usage.
Guideline-Based Recommendations
Diagnosis
Use CT imaging to detect COVID-19-related chest abnormalities including ground-glass opacities and consolidation.
Consider CT for early diagnosis even in asymptomatic patients to guide management.
Management
Employ CT imaging to monitor disease progression and assess treatment efficacy in COVID-19 patients.
Adapt CT protocols based on clinical needs, e.g., thorax native, thorax–abdomen, and pulmonary embolism protocols.
Monitoring & Follow-up
Continuously monitor patient radiation exposure using dose management systems to ensure safety.
Optimize CT protocols and utilize modern technologies to reduce radiation dose while maintaining image quality.
Risks
Be aware of increased radiation exposure risks, especially in vulnerable populations such as elderly and patients with pre-existing conditions.
Balance the diagnostic benefits of CT imaging against potential radiation risks.
Patient & Prescribing Data
Patients undergoing chest CT examinations across 10 hospitals from 2019 to 2024
Chest CT usage increased significantly during the pandemic and stabilized post-pandemic; radiation doses were managed effectively with newer technologies and protocol optimization.
Clinical Best Practices
Implement dose management systems to track and optimize patient radiation exposure.
Adjust CT protocols dynamically to reflect changing clinical indications and pandemic phases.
Maintain vigilance on radiation safety, particularly in vulnerable patient groups.
Use CT imaging judiciously to balance diagnostic benefits with radiation risks.
