“…In both studies the diagnostic accuracy of individual observers varied considerably. Interobserver variation was not reported by MURPHY et al (15). MILNE et al (13) reported only II % interobserver disagreement between 2 radiologists in the interpretation of heart size from p.a.…”

“…However, a normal-sized heart or cardiomegaly were correctly diagnosed in the majority of cases (> 70%) when compared with postmortem cardiac size measurements. The limited utility of chest radiographs in the assessment of left (19) and right ventricular (15) hypertrophy has been demonstrated in other studies. Although plain film cardiac volume determination is somewhat cumbersome and not widely used outside Scandinavia, it offers a reproducible method for heart size determination (1,5,20) and correlates more accurately with left chamber dilatation than visual interpretation or other quantitative measurements based on plain chest film (19).…”

Inter-and intraobserver variation and diagnostic accuracy in estimation of heart size and pulmonary vasculature were evaluated for conventional film-screen technique and image intensifier photofluorography. Interpretation of 218 p.a. and lateral chest films by both imaging techniques was performed independently by 4 readers. Heart size relative to body surface area measured from the plain chest films was used as the reference in cardiac size determination. Overall diagnostic accuracies of conventional radiography and image intensifier photofluorography for cardiomegaly were close to each other, 0.70 vs 0.68, respectively. Specificity of film-screen radiography was better than that of photofluorography (0.92 vs 0.84, p < 0.05). Interobserver agreement was poor both in assessment of the heart size and pulmonary vasculature (range of kappa coefficients 0.18-0.59) while the intraobserver consistency (kappa coefficients 0.60-0.85) was good to excellent. The results suggest a limited usefulness of visual assessment of heart size and pulmonary vasculature in chest roentgenographs.

“…Most prior studies that evaluated the accuracy of chest radiographic criteria for right ventricular enlargement were based on clinical studies or pathologic studies using wall thickness measurements of the right ventricle. 10 Right ventricular areas and right atrial areas were obtained from 2-D echocardiograms using the methods of Bommer and associates.3 Such measurements have been compared with ventriculography in 25 patients with normal right ventricles.3 The normal right ventricular area was 18.0 ± 1.2 cm2. Measurements were also made at autopsy from casts of the normal right ventricles of eight patients.…”
