Hybrid imaging using low-dose, localizing computed tomography enhances lesion localization in renal hyperparathyroidism
(Lippincott, Williams & Wilkins, 2014-03)Background Preoperative localization of parathyroid lesions is potentially beneficial in renal patients with hyperparathyroidism. The aim of this study was to determine the localizing value of hybrid single-photon emission ... -
Metastatiese verkalkinge soos aangetoon met tegnesium-99m-pirofosfaatbeenflikkergrafie : gevalbesprekinge
(Health & Medical Publishing Group, 1982)Two cases of chronic renal failure showing very interesting technetium-99m-pyrophosphate bone scans are presented. In both cases striking uptake of activity was shown in the left ventricle of the heart, the mucosa of the ... -
Methamphetamine dependence with and without psychotic symptoms : a multi-modal brain imaging study
(Elsevier, 2018)Objective: Methamphetamine dependence can lead to psychotic symptoms which may be mediated by frontal, striatal, limbic, and thalamic regions. There are few neuroimaging data that allow comparison of individuals with ... -
Nuclear medicine in South Africa
(HMPG, 2003-08)ENGLISH ABSTRACT: Why should an issue of CME, a publication primarily directed at generalists, be devoted to nuclear medicine? I am reminded from time to time of how unfamiliar many of my colleagues are with this ... -
Peptide receptor radionuclide therapy of neuroendocrine tumors : how important is internal dosimetry?
(Health and Medical Publishing Group, 2019)No abstract available -
Quantifying the risks of radiation exposure
(Health & Medical Publishing Group, 1986-09)The considerations leading to the recommendation of dose-equivalent limits by the International Commision for Radiological Protection are outlined. The dose-equivalent limits are based on radiation risk factors estimated ... -
Two simple inexpensive photographic methods for viewing ECG-gated radionuclide blood pool images
(HMPG, 1979-04)Although the ECG-gated radionuclide blood pool scan (GBPS) has become an established method for studying regional myocardial wall motion, it is usually performed with the aid of an expensive computer system. A simple, ... -
An update on the management of breast cancer in Africa
(BioMed Central, 2017-02-14)ENGLISH SUMMARY : Background: There is limited information about the challenges of cancer management and attempts at improving outcomes in Africa. Even though South and North Africa are better resourceds to tackle the ... -
The use of HEPES-buffer in the production of gallium-68 radiopharmaceuticals – time to reconsider strict pharmacopoeial limits?
(SpringerOpen (part of Springer Nature), 2021-04-01)ENGLISH ABSTRACT: HEPES (4-(2-hydroxyethyl) piperazine-1-ethanesulfonic acid) is a buffer that is used in the radiolabelling of gallium-68 compounds. The beneficial effects of HEPES on molar activity in bioconjugates ... -
Validation of a cost-effective alternative for a radiochromatography method to be used in a developing country
(SpringerOpen (part of Springer Nature), 2020-04-10)Introduction: The radiochemical purity (RCP) of technetium-99m labelled radiopharmaceuticals (RP) is important to ensure optimal scintigraphic image quality. In low-income settings, it may not be possible to use compendial ... -
Validation of equations to estimate glomerular filtration rate in South Africans of mixed ancestry
(Health & Medical Publishing Group, 2020-02-26)Background. The Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations are two commonly used formulae to estimate glomerular filtration rate (GFR) in adults. ... -
Ventilasiestudies van die long met kripton-81m
(HMPG, 1981-08)During a 2-year study period it was found that krypton-81m was useful in routine clinical practice. During this period 1563 technetium-99m perfusion studies and 807 krypton-81m ventilation studies were performed. A distinct ... -
Die waarde van speldgatkollimator-opnames in die flikkergrafiese diagnose van werwelpatologie
(Health & Medical Publishing Group, 1989)Recent findings suggested a possible role for pinhole collimator scintigraphy to differentiate between metastases, infection and fractures of the vertebrae. The aim of this study was to verify these findings and to ascertain ...
