RT Journal Article SR Electronic T1 A New Bolus-Injection System for the Performance of Dynamic Time-Function Studies—a Preliminary Investigation JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 150 OP 153 VO 7 IS 3 A1 Crucitti, Thomas W. A1 Bigham, Keith E. A1 Herrera, Nilo E. YR 1979 UL http://tech.snmjournals.org/content/7/3/150.abstract AB A new bolus-injection system was developed to reduce radiation exposure to nuclear medicine personnel performing dynamic time-function studies, specifically first-pass nuclear cardiology studies. In comparing the new system with the old, two additional parameters were measured: the bolus flow rate characteristics, and the residual activity in the apparatus.
