[Correlations between studies with plain radiography and with cineventriculography in subjects with prior myocardial...

In 86 subjects wiht healed myocardial infarction the reliability of cardiothoracic ratio (C/T), of the left half-diameter (EDTS/m2) and of the overall subjective evaluation of a standard chest X-Ray plate has been tested by comparison to quantitative data drawn by selective cineventriculography. C/T and EDTS/m2 are scarcely reliable, whereas subjective evaluation allowed a separation among different groups of patients, though with wide overlap. Right anterior oblique and lateral views, and the evaluation of the third aortic arch were more useful than left anterior oblique and lowered apex.
