. Is training essential for interpreting cardiac computed tomography?. Acta Radiol. 2009;50:194-200 pubmed publisher
..There was a learning-curve effect in PPV for the radiologists. The diagnostic accuracy of dedicated radiographers indicates that they might be considered to be included as part of the evaluation team. ..
