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

The University of the Free State (UFS) has launched a programme that will provide an accelerated pathway to 25 young scholars with recent PhDs and teach them how to become professors through intensive local and international mentorship, research support and academic training.

The Vice-Chancellor’s Prestige Programme for Young Scholars focuses on the next generation of top researchers in South Africa who will fill the gap left by retiring academics. It will also add significantly to the diversity of the professoriate at the UFS.

No other university in the country has a programme of such scale and intensity for building excellence and diversity through young scholars.

“The programme is highly selective and limited to the most promising young scholars at the university. It will also contribute towards establishing an international reputation for the university and positioning the UFS as one of the best research institutions in the country,” said Prof. Neil Roos, Director of the Postgraduate School at the UFS. He will manage the programme together with Prof. Jackie du Toit, also from the university.

Running for the next three years, the programme will put the 25 scholars through an intensive programme of academic and scholarship support which includes advanced theoretical and methodological training and exposure to leading international scholars in their fields. They will also be exposed to intensive reading and writing programmes, high-level seminar and conference participation and presentation, accelerated publication schedules and personal mentoring and advising plans.

“Scholarship will only grow if there is a critical mass – and this is what we want to achieve at the UFS. We want to create a pool of young scholars, develop and connect them with international scholars and place them at top universities in the world where they can be mentored by the best in their respective fields,” said Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS at the launch of the programme.

According to Prof. Jansen, the UFS aims to draw public intellectuals and A-rated scientists to the campus and make academic work attractive to academics at the university and countrywide.

The group of scholars has a good academic record, with 69% of them completing their PhDs within the last five years. The group is well represented in terms of race and gender; the majority are in the 26 to 30-year age group and specialisations include the social sciences (including education, the humanities and arts) as well as the natural sciences.

“Scholarship develops over time. We are proud and extremely honoured to be selected for this prestigious programme. With this scholarship we acknowledge the responsibility of building the UFS and of extending our knowledge across disciplines. We will establish a scholarly advancement for our university that will enable it to compete with the best in the world,” said Dr Nalize Marais, one of the prestige scholars.

The launch was also attended by members of the university’s International Advisory Council (IAC). This council, which visited the university the past week to advise the leadership on its future positioning strategies, especially in relation to its international aspiration to become a place of scholarship and service among the leading universities in the world, congratulated the UFS on this groundbreaking programme.

“You are lucky to have a leadership that dares to dream and that can act the dream. You are fortunate that your leadership wants to take this university forward and explore new horizons,” said Prof. Aki Saweyrr, former Secretary-General of the Association of African Universities in Ghana and member of the IAC.

Ending the evening’s programme was Dr Gansen Pillay, Vice-President of the National Research Foundation. Prof. Gansen also congratulated the UFS on its visionary and inspirational leadership. “It is a privilege to make a life-changing contribution to research in the world. Universities must take ownership of their own development – which is exactly what the UFS is doing. And, although this is a truly South African programme, it could have an impact on the rest of the world,” he said.
