title: [Determination of heart size and measurements of blood vessels in chest imaging of 4 to 15-year-old children with a healthy cardiovascular system].
abstract: The standard heart size, i.e., heart diameters and heart volume, of normal children aged 4-15 years were obtained. In all cases requiring exact heart-size determination, heart volume calculation is mandatory in children as well as in adults. Statistical work to date has provided the precise calculation of heart volume from plain films in the upright position. Additional plain films in the prone position are unnecessary because there is no evidence of an orthostatic influence on heart volume in children. The percentiles of normal heart volume related to body weight, representing the best correlation to the individual data, are given as well as percentiles related to age. Furthermore, ratios of normal vessel size to the height of the 8th thoracic vertebral body, measured on the same plain film, are given. In addition, the ratio of upper-to-lower lung vessel size is calculated. These ratios are useful criteria in estimating normal vessel size and also in cases with increased pulmonary venous pressure.
