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 is the most integrated campus in the country

“The University of the Free State’s (UFS) Main Campus is the most integrated campus in the country.”

This was said by Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS during the university’s official opening on its Main Campus in Bloemfontein today.

Addressing staff and students, Prof. Jansen said that the first-year students in the majority of the residences are now fully integrated on a 50/50 basis. “The majority of our house committees are now also integrated,” he said.

He used the ladies residence Welwitschia as an example. “When I walked into to this residence last year it consisted only of black female students. When I visited them again this year I could not believe what I saw: the residence is fully integrated and there are white and black students living together. This is an example of our young people’s willingness to live together and we must believe in their potential,” he said.

Prof. Jansen said that the UFS does not want to be good because “good is the enemy of great” (from Jim Collins in his book Good to Great). “We want to be great. This is the year in which our staff and students’ lives will change and this university will change as we take the first steps in making the leap from good to great,” he said.

Prof. Jansen said that there have been many developments at the UFS so far this year. “We have attracted some of the best scholars in the country and other parts of the world to this university, and we will be selecting from among them in the next two weeks. We have also attracted some of the best athletes in the country in our first-year class, including some of the best hockey players,” he said.

Prof. Jansen outlined the following as his priorities for 2010:

  • The phasing in of compulsory class attendance as a way to drastically improve the quality of teaching at the UFS. “This will also enhance our throughput. However, before we can to this, we are going to accelerate the building of larger classrooms to accommodate all our students,” he said.
  • The appointment of a senior vice-rector in the near future, who will manage the day to day operations of the UFS;
  • To market the UFS to the best and most promising schools in South Africa. “This will start next week when I will be visiting schools in the Eastern Cape.”
  • To raise R100 million to enable more students with talent to study at the UFS, and to build an endowment to be proud of for the future of the university;
  • To upgrade the infrastructure in the residences;
  • To require every member of the university’s academic staff to publish every year;
  • To train administrative and support staff so that a world-class service culture can be created which takes every student, every parent and every staff member seriously; and
  • To insist that the conditions of service of staff working for agencies outside the UFS be improved by increasing the minimum remuneration dramatically and by making study benefits available to them as well. “We will not renew our tenders with outside agencies unless they raise the minimum wage of their staff,” he said.

Prof. Jansen said that he was extremely proud of the Student Representative Council’s (SRC) leadership and what they have achieved so far during their term. He also thanked the staff for their hard work and the excellence they bring to the UFS.
