心脏核医学(nuclear cardiology)是注射放射性同位素后,以安置在体外的器材对由心脏组织发出的辐射进行检测、显象和定量。近来人们对这种比较新颖的检查技术,兴趣逐渐增加。它反映应用核技术阐明心脏病人的病理生理和诊断项目的水平,正在不断提高。由于这些检查只需静脉注射少量存在时间很短的同位素,故反复检查亦甚安全。 Nuclear cardiology is the detection, visualization and quantitation of radiation emitted by heart tissue with devices placed outside the body after radioisotope injection. Interest has recently increased in this relatively new inspection technique. It reflects the increasing use of nuclear techniques to elucidate the pathophysiology and diagnostic programs of cardiac patients. Because these tests only need a small amount of intravenous injection of a very short time isotope, it is also safe to repeatedly check.
