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 celebrates Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities

Future sustainable partnerships in education will survive only if all partners are committed, honest, and transparent.

This is the view expressed by the Free State MEC for Education and UFS Council member, Tate Makgoe, during the panel discussion at the Qwaqwa Campus of the University of the Free State celebrating Kagiso Trust’s 30 years of commitment to the empowerment of impoverished communities. The topic was “The future partnership models for education in Africa”.

“Over the years, the partnership between the Free State Department of Education, the UFS, and Kagiso Trust has helped to expose the potential in our mainly rural children in the Qwaqwa area of the Thabo Mofutsanyana district,” said Makgoe.

”When we started in 2009, the matric pass rate in the district was 64%, and this rose to 87% in 2014. In Qwaqwa alone, we have managed to build 51 computer and 26 physical sciences laboratories. It was these laboratories that enabled the Free State to be the best performing province in the Physical Sciences in 2013,” added Makgoe.

“None of these achievements would have been possible if all the partners had not been committed to the course. Partnerships built on honesty and transparency are the best model, which we hope to export to other provinces and, indeed, countries,” Makgoe said.

Representing the UFS on the panel was the Director of Community Engagement, Bishop Billy Ramahlele, who added that collaborations can be successful only if the leadership was exemplary.

“As the university, we have had many collaboration with various government departments, and great strides have been achieved only with the Department of Education under the leadership of MEC Makgoe,” said Ramahlele.

”With the MEC on board, the UFS ended up dedicating its South Campus in Bloemfontein to supporting Free State schools. We now have 70 schools that benefit from live television broadcasts of lessons by some of our outstanding academics. This also enables our best academics to make a valued contribution to empowering our teachers. It also allows the university to maximise scarce resources to attain social cohesion,” he said.

In his remarks, Kagiso Trust Trustee, Dean Zwo Nevhutalu, said that Kagiso Trust was looking forward to continue working with its partners to maximise outcomes through limited resources.

“Kagiso Trust will continue to work with the poor and the marginalised and there is no better partner than the government itself. The government provides basic services, and education is one of them. This allows us to be innovative and not just dump books and equipment at schools because we are forced to by our corporate social investment obligations. Therefore, we challenge the government also to be innovative in building a sustainable future partnership model in education,” he said.

Among the dignitaries attending the panel discussion were Kagiso Trust Chairman, Dr Frank Chikane, and the late Dr Beyers Naude’s family.
