Abstract
A portable echographic apparatus (Hitachi model EUB-200) in which modes M and B are recorded simultaneously was used. To raise the degree of resolution of a picture produced by echography, a video casette recorder for home use was remodelled into a super high band and used with the apparatus. Then, echography was carried out in clinical cases of canine filariasis, canine mitral regurgitation, canine myocardial infarction accompanied with endocarditis, and feline myocardosis. Each picture obtained from it was reproduced into a slow film for scrutiny.
As a result, it was possible to locate the site of parasitization even with a small number of filariae rather accurately. The new method was effective for the diagnosis of valvovelar escape in mitral regurgitation and for morphological observation of the heart in myocardosis. It failed, however, to find any characteristic change in the case of endocarditis or myocardial infarction.
