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

Prof Frederick Fourie to step down as UFS rector
2008-09-08

“It is with sadness that I hereby announce my intention to step down as rector and vice-chancellor of the University of the Free State (UFS) in the 4th quarter of this year.

Obviously this decision has not been taken lightly. After careful consideration I am, however, convinced that this is as far as I can take the UFS as vice-chancellor and rector. This flows primarily from the exhausting times that I have experienced during the past nine years, first as vice-rector (since 1999) and then as rector (since 2003), in managing and implementing several complex strategic projects.

The challenges and complexities of continuous change management at a higher education institution, and specifically the demands of further dynamic development and transformation at the UFS, demand enormous amounts of emotional energy and drive. For me the stress due to, especially, the political divisions and tensions in the UFS Council and the broader university community during the past year has been extremely draining. The broader institution and its people also show signs of trauma.

I think it is time for new and fresh leadership, especially in the light of the transformation challenges of the UFS.

I have thus decided to step down in the interest of transformation and the further dynamic development of the UFS.

Having been on sabbatical leave since May, I will not return to take up my post. I will remain on leave until my official date of retirement from office. (The exact date must still be determined.)

I am grateful for the opportunity to have been at the helm of the UFS and to help the institution cross several bridges. During the past nine years I have been privileged to lead large strategic projects together with many dedicated and talented UFS colleagues. It has been a wonderful experience of thinking and working together in order to elevate the functioning of the University to new levels in several key areas.

One of the most important projects was the financial turnaround strategy of 2000-2005, which took the UFS from a financial crisis to a situation where currently it annually has almost R100 million of discretionary funding available to spend on strategic projects, and where staff remuneration and promotion opportunities have increased dramatically since 2000. In this period the UFS has also grown from approximately 10 000 students to more than 27 000 in 2008.

A second was the strategy to invest strongly in the academic core and notably research, research capacity and research apparatus. Since 2003 research outputs have increased by approximately 50% - a significant accomplishment of our researchers and faculties. In conjunction with this, the launch of the six strategic academic clusters (focus areas) should create the basis for the continued growth in the national and international stature of the UFS in future. The development of the national leadership role of the UFS with regard to community service also was a special and successful project.

A third large strategic project was the progress with regard to diversity, the balanced multilingualism policy in the academe as well as the administration, the employment equity plan, the UFS transformation plan and especially the institutional charter – which could lay the foundation for a university where one and all can experience a true sense of belonging amidst diversity. These have been important steps that we can feel proud of (although much work obviously remains with regard to non-racialism and also non-sexism).

As far as residences are concerned, it was historically significant that this time, in contrast to 1997/8, the UFS succeeded in crossing the bridge of diversity and integration in residences – with due regard to the difficulties we faced. Hopefully this will considerably ease the task of my successor and her/his management team in managing diversity and in pursuing best practice transformation.

A fourth large project was the large-scale upgrading and development of infrastructure, academic buildings and facilities as well as support service facilities, student facilities and pedestrian walkways. The objective was a campus of the highest quality and aesthetics to effect a lasting improvement in their work- and living environment for staff and students. Indeed, the UFS Main Campus today is seen as an example of sensitive and high quality campus planning.

Other initiatives which haven’t borne fruit yet are, for example, those with regard to entrepreneurial activities, sport development and sport business development, and the possible establishment of an engineering programme or faculty at the UFS.

On the whole the most important thing for me has been the progress in establishing a deep commitment to quality and equity/fairness and in boosting the national and international profile of the UFS as a high quality progressive university. Of course, justice, equity and quality intrinsically are challenges which require daily dedication to make it an ingrained habit.

I wish to thank all those people with whom I could work during the past years in tackling large and complex challenges with mutual loyalty, shared wisdom and effort – from the Financial Turnaround Team to the Exco, the Executive Management, the Faculties, the Senate, support service divisions, the University Council and several committees and task teams”.
