Adsorption of radiopharmaceuticals to syringes leads to lower administered activity than intended

Autor: R. D. Gunasekera, A B Mostafa, Alp Notghi, L. K. Harding

Publikováno v: Nuclear Medicine Communications. 22:493-497

In this study we examined the delivered activity of radiopharmaceuticals injected into patients and the various factors which lead to incomplete delivery. Four commonly used 99Tcm radiopharmaceuticals were included, namely pertechnetate, methylene di

We have developed a technique for measuring the pulmonary granulocyte pool (PGP) as a fraction of the whole body total blood granulocyte pool (TBGP). The technique “captures” a dose of 99mTc-labeled granulocytes in a region of interest (ROI) over

Clearance kinetics of solutes used to measure glomerular filtration rate

Autor: M. Mubashar, R. D. Gunasekera, C. Cousins, M. J. Myers, R. Strong, S. Mohammadtaghi, A. M. Peters

Publikováno v: Nuclear medicine communications. 20(11)

Agents used to measure glomerular filtration rate (GFR) give a biexponential plasma disappearance curve on multiple peripheral venous sampling between 20 min and 4 h after intravenous injection. These two exponentials are generally regarded to repres

Comparative kinetics of microvascular inulin and 99mTc-labelled diethylenetriaminepenta-acetic acid exchange

Autor: A. M. Peters, S. Mohammadtaghi, M. J. Myers, C. Cousins, M. Mubashar, R. D. Gunasekera, R. Strong

Publikováno v: Clinical science (London, England : 1979). 93(5)

1. After simultaneous intravenous injection as a mixture, 99mTc-labelled diethylenetriaminepentaacetic acid (99mTc-DTPA; molecular mass 492 Da) and inulin (∼6000 Da) gave arterial plasma clearance curves consisting of three exponentials, the time c

Glomerular filtration rate in relation to extracellular fluid volume: similarity between 99mTc-DTPA and inulin

Autor: R D Gunasekera, D J Allison, A. M. Peters

Publikováno v: European journal of nuclear medicine. 23(1)

The rate constant (alpha2) of the terminal exponential of the technetium-99m diethylene triamine penta-acetic acid (DTPA) plasma clearance curve is close to the ratio of glomerular filtration rate (GFR) to extracellular fluid volume (ECV) and is ther

Hypocalcemic actions of amylin amide in humans

Autor: S J, Wimalawansa, R D, Gunasekera, H K, Datta

Publikováno v: Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research. 7(9)

Amylin (also known as islet amyloid polypeptide and diabetes-associated peptide) has recently been shown by us to have a potent hypocalcemic effect in rat and rabbit owing to inhibition of osteoclast-mediated bone resorption. The hypocalcemic potency
