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

In January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

FREDERICK FOURIE

IN January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

While this is merely the beginning of a long and complex process, it does represent a major milestone in overcoming the apartheid legacy in education, realising the anti-apartheid goal of a single non-racial university serving the Free State.

The incorporation is also part of the minister's broader restructuring of the higher education landscape in South Africa - a process which aims to reshape the ideologically driven legacy of the past.

In contrast to the past educational and social engineering that took place, the current process of incorporating the Qwa-Qwa campus of Unin into the UFS is informed by three fundamentally progressive policy objectives, clearly outlined in the education white paper 3: (A framework for the transformation of higher education):

To meet the demands of social justice to address the social and structural inequalities that characterise higher education.

To address the challenges of globalisation, in particular the role of knowledge and information processing in driving social and economic development.

To ensure that limited resources are effectively and efficiently utilised, given the competing and equally pressing priorities in other social sectors.

Besides informing the way the UFS is managing the current incorporation, these policy objectives have also informed the transformation of the UFS as an institution over the past five years.

In 2001, former president Nelson Mandela lauded the success of the UFS in managing this transformation, by describing the campus as a model of multiculturalism and multilingualism. This was at his acceptance of an honorary doctorate from the UFS.

Indeed our vision for the Qwa-Qwa campus as a branch of the UFS is exactly the same as it is for the main UFS campus - a model of transformation, academic excellence, community engagement and financial sustainability, building on the histories and strengths of both the Qwa-Qwa campus and the UFS (Bloemfontein campus).

Realising this vision will be a giant leap forward in establishing a unified higher education landscape in the Free State.

In more concrete terms, the UFS is working towards this vision by focusing on the following areas of intervention: access and equity; academic renewal; investment in facilities; and sound financial management.

These interventions are being made not to preserve any vestiges of privilege or superiority, but precisely to increase access for students from poor backgrounds and to promote equity and representivity among all staff.

The current growth phase of the UFS has seen student enrolment almost double over the past five years, in particular black students, who now constitute approximately 55 percent of the student population of nearly 18 000 (including off-campus and online students).

But it has not just been a numbers game. Our approach has been to ensure access with success.

Our admissions policy, coupled with the academic support and "career preparation" programmes we offer, have resulted in significant successes for students who otherwise would not have been allowed to study at a university.

This will be continued at Qwa-Qwa as well.

Our academic offerings too have undergone dramatic change. We have become the first university in the country to offer a degree programme based on the recognition of prior learning (RPL).

This is not just a matter of academic renewal but of access as well, especially for working adults in our country who were previously denied a university education.

As for the sound financial management of the UFS (including the Qwa-Qwa campus), this is being done not for the sake of saving a few rands and cents, but for the greater value to our society that comes from having sustainable institutions.

It is sustainable universities that can make long-term investments to fund employment equity, provide information technology for students, upgrade laboratories, construct new buildings, develop research capacity, and provide a safe environment for students and staff, as is happening now at the UFS.

As a result of such management, a practical benefit for prospective students at the Qwa-Qwa campus of the UFS will be lower academic fees in some cases compared with the Unin fees.

As is the case with all these processes, there are concerns from staff and students at Qwa-Qwa and the broader community of the region that the Qwa-Qwa campus serves.

To get the campus viable and to ensure its continuation in the short term, tough choices had to be made by the minister of education regarding which programmes to offer and fund.

But we have been encouraged by the community's understanding that these concerns can be addresed over time as the campus becomes financially viable.

Meetings between the top mangement of the UFS and community representatives, staff and students at Qwa-Qwa have laid the basis for building a climate of trust in such a complex process.

We should not be captives of the past divisions but build this new unified higher education landscape that can meet our country's developmental needs.

It should be a higher education landscape that is based on broadening access, promoting equity and social justice, developing academic excellence, and the effective and efficient management of scarce resources. This should be our common common objective.
