现今日本心血管医学领域给人留下的一个重要印象恐怕是画家诊断的进步,尤其是无创性画象诊断的进步。50、60年代,心导管检查以及心血管造影在日本普遍开展,促进了日本心脏病学的发展,之后随着相关连科学技术的进步,应用非创伤性的方法,得到不少过去只靠有创性诊断手段才能提供的相同医疗情报,在每年的医学会上,如规模庞大的日本循环器总会、日本心脏图学会和日本超声波医学会等等学会上,都报告大量画象诊断的研究成果。一、超声心动图诊断,60年代,日本超声心动图装置处于第一世代,即M型超声心动图时代。自70年代开始,便进入第二世代,即B形断层超声心动图(two-dimensionalechocardiography)。这个断层法的特点是将心脏构造通过超声回波再现,使我们人眼能看到心脏的断层结构。在此同时,应用了Doppler技术了解心脏血管的血流情报,
An important impression left in the field of cardiovascular medicine in Japan today is probably the improvement in the diagnosis of painters, especially in the diagnosis of noninvasive portraiture. In the 1950s and 1960s, cardiac catheterization and cardiovascular angiography were commonly performed in Japan to promote the development of Japanese cardiology. Later, with the progress of related science and technology, non-invasive methods were applied to obtain the results of many studies in the past. The same medical information provided by invasive diagnostic tools has been reported in the annual medical conferences such as the Japan Society of Circulating Circulators, the Japanese Society of Cardiology and the Japanese Society of Ultrasound in Medicine, etc. Results. First, the echocardiographic diagnosis, 60’s, Japan echocardiography device in the first generation, that is, M-mode echocardiography era. Since the 1970s, it has entered the second generation, namely B-mode echocardiography (two-dimensionalechocardiography). This fault method is characterized by the echocardiographic reconstruction of the heart, so that our human eye can see the heart’s fault structure. At the same time, the application of Doppler technology to understand the blood flow of cardiovascular information,
