The role of radiology in early detection
Evaluating new techniques for disease prevention-COVID-19 case study
Keywords:
COVID-19, radiology, chest X-ray, computed tomography, ultrasound imaging, diagnostic techniquesAbstract
Introduction: The outbreak of COVID-19, caused by the novel coronavirus SARS-CoV-2, has prompted the use of various diagnostic methods to manage the disease. Although Real-Time Reverse Transcription-Polymerase Chain Reaction (RT-PCR) is the gold standard for COVID-19 diagnosis, its limitations in sensitivity and availability have highlighted the role of radiological techniques. Aim: This study aims to evaluate the effectiveness of different radiological techniques—chest X-ray (CXR), computed tomography (CT), and ultrasound imaging—in the early detection and management of COVID-19. Methods: A review of existing literature and case studies was conducted to assess the diagnostic utility, sensitivity, and limitations of CXR, CT, and ultrasound in COVID-19. Comparative analysis was performed based on imaging characteristics, diagnostic accuracy, and clinical outcomes. Results: CT is identified as the most sensitive modality for detecting COVID-19, showing high sensitivity in identifying lung abnormalities and disease progression. CXR, while cost-effective and widely available, offers lower sensitivity and is less effective for early-stage disease. Ultrasound imaging, though less common, provides useful supplementary information and is beneficial for bedside assessments. Conclusion: CT is crucial for diagnosing and monitoring COVID-19 due to its high sensitivity and detailed imaging capabilities.
