The Interpretation Of Computed Tomography Pulmonary Angiography Evaluation Of Compliance Between Emergency Medical Assistants And Radiologists

Abstract

Purpose: Computed tomography pulmonary angiography (CTPA) is an effective method far the evaluation of patients with suspected pulmonary thromboembolism (PTE) and should be interpreted quickly and accurately. We aimed ta determine the agreement between emergency medicine assistants (EMAs) and radiology assistants (RA) and specialists (RS) in the evaluation of CTPA Materials and Methods: 11 EMAs, one RA and one RS participated in the study. 100 CTPA images were re-reported. The participating RA evaluated 100 CTPAs and 11 EMAs evaluated 20 randomised CTPAs aut of 100. The Kappa statistic was used ta assess agreement, and the Douglas G. Altman classifıcation (K<0.20 poor, K: 0.21-0.40 fair, K: 0.41-0.60 moderate, K: 0.61-0.80 good, K: 0.81-1.00 very good) was used ta grade consistency. Results: The agreement between EMA and RS was 79.1% far the presence of PTE, 59.1% far the location, 84.5% far the parenchymal fınding, 70.0% far the name of the parenchymal fınding. Moderate agreement was found between EMA and RS in the assessment of the presence of PTE (Kappa: 0.590) Conclusion: There is moderate agreement between EMA and RS in CTPA evaluation.
