Abstrakt: | With the technic at present commonly used in angiocardiography there may be difficulty in the localization of the contrast medium in the heart as well as in identification of the various chambers of the heart and estimation of their volume and configuration. To overcome these difficulties specific technical arrangements have been necessary.From the commencement of the injection and until the contrast medium has passed through the heart, a series of roentgenograms must be taken, from which the various cavities of the heart and the vessels can be assessed. The intervals between exposures should be chosen so that the passage of the contrast medium through the different chambers of the heart may be followed. Robb and Steinberg as well as other investigators have worked with roentgenography in one projection only. If the examination demands supplementary views with further projections it is necessary to repeat the entire examination after repeated injection |
