Time\u2010activity curves were generated over the right atrium and ventricle, and several quantitative parameters were derived from the curves. It was concluded that in the absence of right\u2010sided valvular incompetence, the time\u2010activity curves show the greatest abnormality in the cardiac chambers distal to the left\u2010to\u2010right shunt. The right ventricular curve is typically altered in ASD but cannot be relied upon to differentiate VSD or PDA. The identification of ASD is assisted by the use of two of the parameters, the count ratio C4:C1 and time ratio T2:T1.<\/jats:p>","DOI":"10.1002\/ccd.1810080505","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T07:55:28Z","timestamp":1172735728000},"page":"459-467","source":"Crossref","is-referenced-by-count":2,"title":["First\u2010pass radionuclide angiocardiography in the determination of left\u2010to\u2010right cardiac shunt site in children"],"prefix":"10.1002","volume":"8","author":[{"given":"Jia\u2010He","family":"Tian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.
