There is no doubt that an institution like the University of the Free State (UFS), with its calibre and pedigree, needs a PET/CT machine (medical-imaging device that simultaneously and clearly reveals both anatomical details and metabolic processes within the body), particular in oncology, in improving the management of patients. 

This is according to Prof Willy Vangu, Chief Specialist and Head of Nuclear Medicine at the University of the Witwatersrand, who was a guest lecturer on 8 September 2022 at the Department of Nuclear Medicine at the UFS.

Positron emission tomography (PET) is a type of nuclear medicine imaging modality that measures the metabolic activity of the cells of body tissues. PET imaging is useful in the evaluation of patients with neurological, cardiac, infection, inflammation, and most importantly oncological conditions. Through its ability to detect metabolic changes very early, it can detect disease conditions that might not be easily detected on other forms of anatomical imaging.

Role of PET/CT in different clinical scenarios

In his lecture, Prof Vangu talked about the role of PET/CT in different clinical scenarios. By giving practical examples, he explained the role of PET/CT in different aspects of clinical medicine, including brain imaging for dementia, movement disorder and cerebrovascular reserve. 

“Looking at dementia, we will focus on one of diseases that is today becoming a major source of health concern, Alzheimer's disease. The latest Alzheimer's report that was published in 2018 stated that there are 50 million individuals currently suffering from Alzheimer's. They forecast that in 30 years we are going to have more than 150 million people suffering from this disease. PET/CT imaging can identify very early the typical patterns associated with all the different types of dementias, including Alzheimer's disease…”

For cardiac application, Prof Vangu said there are so many indications for PET/CT in cardiac imaging. One of the most important is the assessment of myocardial viability, in patients who have suffered from cardiomyopathy due to ischemic heart disease. PET/CT offers a noninvasive method of identifying viable myocardium that would benefit from revascularisation, with a very high diagnostic accuracy. 

Prof Vangu, who is also the head of nuclear medicine at the Charlotte Maxeke Johannesburg Academic and Chris Hani Baragwanath hospitals as well as head of the department for radiation sciences at the University of the Witwatersrand, said PET has been around for many years and is not something new. However, in clinical practice, PET imaging became significant with a breakthrough that occurred with the production of the glucose analogue tracer, 18F-fluorodeoxyglucose (FDG). This tracer in PET/CT imaging has revolutionised the management of cancer patients for the oncologist. It offers the ability of more accurate cancer staging, assessment of treatment response, assessment of disease recurrence and in some situations, surveillance. It has the ability to predict early which cancer patients will benefit from a particular drug, thereby giving the oncologist an idea on either to de-escalate treatment or change to a second line regimen very early on in the management.

PET/CT came onto the market only in the year 2001, when it was launched for the first time by David Townsend (a physicist) and Ronald Nutt (electrical engineer). As at today, almost every institution in the country has at least one PET/CT machine.


“Looking at clinical applications, which is really the crux of the lecture today, there are so many clinical applications to talk about. You need a full week of a PET/CT symposium to go through all of them (and) maybe that might not even be enough. We can at least from this talk have an idea on how PET/CT can be applied in clinical medicine,” said Prof Vangu.

No other road for the university but to get a PET/CT machine

He also showed the impact and results that PET/CT imaging had in the management of infection and inflammation including TB. He said the role of PET/CT in TB is for monitoring of treatment, identification of extrapulmonary TB and prognosis. 

In concluding his lecture, he said there is no other road for the university but to get a PET/CT machine. “There is no argument about it. The institution needs it to improve the management of patients, especially the oncology and cardiology patients. Confidently making the decision on which patients to treat, how to treat them, identifying and evaluating their true response to therapy requires a PET/CT machine.

“I am happy to hear that the policy- and decisions-makers in the province and the university are looking forward to having a PET/CT machine,” he said later. 

Dr Osayande Evbuomwan, nuclear medicine specialist and Senior Lecturer, and Dr Gerrit Engelbrecht, Clinical Head of the Department of Nuclear Medicine at the UFS, are both looking forward of having a PET/CT in the department because in addition to its use in clinical setting, it has a huge role to play in research and training postgraduate students, as PET/CT imaging makes up a huge chunk of the postgraduate training curriculum

UFS School of Nursing opens new frontiers at 40
2009-11-16

The opening of the virtual facility of the School of Nursing at the University of the Free State (UFS) and a gala dinner to celebrate the School’s 40th year of existence took place on the Main Campus in Bloemfontein this week. At the opening were, among others, from the left: Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS; Dr Oluseyi Oyedele and Ms Viona Munjeri, both from The Atlantic Philanthropies; and Prof. Anita van der Merwe, Head of the School of Nursing at the UFS.

All eyes in the nursing profession in South Africa were turned to the University of the Free State (UFS) when the School of Nursing opened a state-of-the-art virtual health training and learning facility and celebrated its 40th year of existence with a gala dinner on the Main Campus in Bloemfontein this week.

The lustrous events were attended by dignitaries from all spheres of the health-care fraternity in South Africa.

The new virtual facility, The Space, is made possible by a grant of R16 million from The Atlantic Philanthropies and R1 million from the UFS. The Atlantic Philanthropies organisation is an international philanthropic organisation that is going to inject R70 million into nursing in South African over the next four years. The initiative will enhance nursing education and step up the quality of health-care delivery in South Africa. Four major grants were made to universities in South Africa, of which the UFS is one.

With the facility at the UFS School of Nursing, nursing education is propelled into the future. Prof. Anita van der Merwe, Head of the School of Nursing, says, “The virtual learning facility is a very new way of thinking and teaching. At the moment, theory and practice are separated, as theory is often taught in the mornings, followed by practical settings later in the day. Learner nurses then also go to clinical facilities for their practicals where the quality of care is declining and human resources are a problem.

“We believe that with new technologies such as e-learning and high-tech computer-mediated equipment we can use the ‘virtual world’ to bridge the theory-practice gap in the same location.”

Prof. Van der Merwe says the project is essentially about transformation: taking a stand against stagnation in nursing education and practice and daring to be different.

In the new virtual facility nurses will have the best of three worlds – the expertise of the facilitator/educator, simulation technology, and a vast selection of on-line and off-line software, exposing them to blogs, broadcasting and enhancing computer literacy. This will attract both the new “millennial” generation, which tends to be technologically competent, as well as the older learner because of the unthreatening learning environment.

The core space will accommodate 40 to 60 students and is designed to encourage informal, collaborative learning and practice simultaneously. It will have a demarcated area for “patients” (such as advanced adult and baby patient simulators) and a “clinic space” allowing for role play.

At the gala dinner, Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS commended nurses in South Africa for their caring role, but also expressed his concern that South African has lost its deep sense of care. South Africa is at a critical point and the country can be changed if a deep sense of care can be embedded again.

About forty nursing educators from all over South Africa attended an exploratory workshop in the facility today and the last meeting of the Forum of University Deans in South Africa (FUNDISA) also coincided with the festivities at the School of Nursing.
