[Contrast echography of uterine tumors using albumin-carbon dioxide-foam].

A method of contrast echography with albumin-carbon dioxide foam is reported. 140 women aged 20 to 60 were investigated. By filling the uterine cavity and in some cases the tubes the sagittal and longitudinal size of the uterus were determined and tumourous nodes in the uterine well were demonstrated.

[Background correction in inhalation scintigraphy of the lungs using 133Xe].

Based on the regularity of decreasing the blood volumes from the internal edge of the lung to its periphery the authors proposed a method of gradient background correction in inhalation scintigraphy of the lungs with 133Xe. The background is detached on each image line separately for the right and left lungs. Software was developed for the implementation of this technique of background correction for any computer with a FORTRAN-IV translator.
