(Health & Medical Publishing Group, 2016)Individualised patient treatment approaches demand precise determination of initial disease extent combined with early, accurate assessment of response to treatment, which is made possible by positron emission tomography/computed ... -
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 ... -
Monitoring various eluate characteristics of the iThemba LABS SnO2-based 68Ge/68Ga generator over time and validation of quality control methods for the radiochemical purity assessment of 68Ga-labelled DOTA peptide formulations
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH SUMMARY : PET imaging with gallium-68 (68Ga) has become widely used due to the availability of 68Ge/68Ga generators and DOTA-derivatised peptide ligands for radiolabelling. The purpose of this study was to monitor ... -
Evaluation of the effect of low and intermediate frequency electromagnetic waves on radiosensitivity
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH SUMMARY : The incidence of epidemic Kaposi’s sarcoma in HIV/AIDS patients is high due to their compromised immune system. HIV-positive individuals presenting with cancer tend to be more sensitive to ionizing radiation ... -
Evaluation of small molecule inhibitors of HER2, PI3K, mTOR and Bcl-2 for their radiomodulatory effects in human breast cancer cell lines
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH SUMMARY : Breast cancer remains the most commonly diagnosed cancer in women. It is responsible for 32% of all cancers and 15% of all cancer-related deaths in females. Patients with triple-negative breast ... -
Validation of radiochemical purity analysis methods used in two tertiary public hospitals in South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH SUMMARY : Radiopharmaceutical kits are supplied by manufacturers with package inserts containing information about the kit including validated methods of preparation and radiochemical purity (RCP) analysis. Validated ... -
Targeting the EBFR and PI3K pathways as a therapeutic strategy for prostate cancer
(Stellenbosch : Stellenbosch University, 2015-04)ENGLISH ABSTRACT: Targeted therapy for prostate cancer may offer potential improvement over current conventional therapies because of its specificity. Although conventional treatments are effective, they are not curative ... -
Radiosensitisation of low HER-2 expressing human breast cancer cell lines
(Stellenbosch : Stellenbosch University, 2015-04)ENGLISH ABSTRACT: Breast Cancer remains one of the world’s leading causes of cancer related deaths amongst women. Its treatment has evolved from invasive, highly toxic therapies to treatments that possess a higher ... -
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 ... -
Extended Cr-51 RBC combined with Tc-99m RBC for the detection and localisation of occult GIT bleeding
(Stellenbosch : Stellenbosch University, 2014-04)ENGLISH ABSTRACT: Background Occult blood loss from the gastrointestinal tract (GIT), causing iron deficiency often with anaemia, can be diagnostically and therapeutically challenging. This is because the endoscopic and ... -
The added value of SPECT/CT in complicated osteomyelitis
(Stellenbosch : Stellenbosch University, 2013-12)ENGLISH ABSTRACT: Background: The detection of bone infection can be very difficult especially in bone with altered structure due to prior trauma or surgical procedures. Complicated osteomyelitis (COM) is becoming a public ... -
Imaging of renal hyperparathyroidism using SPECT/CT with low-dose localizing CT
(Stellenbosch : Stellenbosch University, 2013-12)ENGLISH ABSTRACT: Background: Hybrid imaging using single photon emission computed tomography/low dose (x-ray) computed tomography (SPECT/LDCT) is of benefit in preoperative scintigraphy of primary hyperparathyroidism. The ... -
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 ... -
An investigation of the contribution of Single Photon Emission Computed Tomography to the diagnosis of skeletal metastases using bone scan in the African context
(Stellenbosch : Stellenbosch University, 2003-12)ENGLISH ABSTRACT: Planar bone scintigraphy is highly sensitive but it may not be sensitive enough to detect subtle lesions in complex bony structures such as the spine. The accurate anatomic localisation of lesions in ... -
