We read with great interest a recent article which was published in Academic Radiology by Maschke and colleagues (
1
). The authors evaluated the value and possible benefit of conventional digital subtraction
angiography (DSA) and combined C-arm computed tomography (CACT) of the pulmonary arteries
in the diagnostic work-up of patients with suspected chronic thromboembolic pulmonary
hypertension (CTEPH). They used Cohen’s kappa to determine the intermodality and interobserver
agreement and to assess the correlation of DSA consensus (DSAcons) and CACT consensus
(CACTcons) with the standard of reference (SOR) to evaluate the impact of each modality
on the final diagnosis. We congratulate the authors on their research but raise concerns
about the use of Cohen’s kappa to estimate the agreements.To read this article in full you will need to make a payment
