We report the development of a method for obtaining right-ventricular radionuclide
angiograms using continuous peripheral intravenous infusion of the ultra-short-lived nuclide …

A method for imaging the right side of the heart (atrium, ventricle and main pulmonary artery)
and for assessment of RV systolic function (ejection fraction and ejection rate) is described …

JVec ecognition of the importance of right ventricular function (/) has led to the interest in
methods for its noninvasivc assessment (2). Because of the right ventri cle's complex …

Krypton-81m, a radionuclide emitting a 190 kev gamma ray, has a half-life of 13 seconds. It
is a radioisotope of an inert water-soluble noble gas and is produced at a constant rate by …

The ultrashort-lived radionuclide krypton-Sim, eluted in 5% dextrose from a bedside
rubidium-81m generator, was intravenously infused for rapid imaging of the right-sided heart …

The availability of krypton-81 m suitable for intravenous injection provides an easy means
for assessing right ventricular function. The superimposition of the other heart chambers …

MYERS to achieve directionality by means of the two back to-back ±y-rays of 38K, which
are emitted 180 deg to each other, should make this instrument at least ten times more …

[en] The measurement of tissue perfusion using the ratio of sup (81m) Kr to 81 Rb is based
on the fact that rubidium is rapidly distributed in the intracellular space, while krypton is a …

The complex geometry of the right ventricle makes the use of radionuclides an attractive
method for assessing right ventricular function. The use of the gated 133Xetechnique for this …

Krjplon-81m has been continuously eluted in 5% dextrose from a cyclotron-made rubidium-
81 generator. The unique physical properties of this inert freely diffusible gas (half-life 13 …
