We investigated the feasibility of using 191mIr (half-life, 5 s) to measure rapid dynamic
alterations in differential renal blood flow. Methods: A nonobstructive constant renal pelvic …

Iridium-191m (191mIr, t1/2= 4.96 sec), an ultra-short lived tracer, has turned out to be
suitable for gamma imaging. It can be obtained in high yields from an 191Os/191mIr …

Ultrashort-lived tracer 191mIr (T1/2= 4.92 s) can be obtained with a high yield from an
191Os/191mIr generator with a low 191Os breakthrough. It was eluated directly into the tail …

Continuous infusion of iridium-191m (t 1/2 á= á5ás), produced with an 191 Os/191m Ir
generator, was used to obtain rapid high-resolution single-photon emission tomography …

Objective: The aim of this study was to validate the quantification of absolute renal perfusion
(RP) determined by dynamic magnetic resonance imaging (MRI) and contrast media using …

Abstract 99m Tc-labelled mercapto-acetyltriglycine (MAG-3) has recently been proposed as
an ortho-iodohippurate (OIH) substitute for dynamic renal imaging. Experience with MAG-3 …

Purpose To evaluate whether real-time and intermittent pulse inversion technology (PI)
allows the analysis of blood flow in renal macro-and microcirculation. Materials and methods …

We have successfully demonstrated with chronically implanted blood flow probes in a pig
model that renal uptake of Rb-82 is indeed sensitive to acute renal blood flow changes. Two …

The aim of this study was to evaluate the quality of dynamic radionuclide renal imaging in
Finland. Nineteen nuclear medicine departments participated. A functional renal phantom …
