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

Fundraising campaign launched to help feed hungry students

The University of the Free State (UFS) received over R200 000 for its No Student Hungry (NSH) Programme at the NSH launch dinner on Friday 23 March 2012 in Bloemfontein.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS as well as founder of the NSH Programme donated R100 000 from the proceeds of his book We Need to Talk to this programme. Standard Bank also donated R30 000.

An additional amount of about R90 000 was raised by means of pledges made by guests and the auctioning of several items. These items were donated by local companies and university staff.

The No Student Hungry Programme (NSH) aims to raise funds to provide modest food bursaries for needy students and give them daily access to a balanced meal.
Prof. Jansen started the NSH programme in 2011 with the proceeds of his book, We Need to Talk.

The NSH funds more than 100 students in the hope of helping them to excel in their academic endeavours and, ultimately, to obtain their degrees.

In 2011, Prof. Jansen discovered that a significant number of students were studying without eating on a regular basis. These were often students with strong academic records but without adequate funding to sustain themselves with regular meals.

The project was established in January 2011 when the NSH Team started to develop the structure and processes of the programme. The first 100 students who were awarded the food bursaries started using their student cards for daily meals on campus on 1 April 2011.

“The No Student Hungry Campaign is not only about creating a university campus that cares. It is about creating a country where being human matters. Our students on the NSH project are amazing young people. They struggle to get by, but they have great potential and achieve good marks," Prof. Jansen said on Friday.

Prof. Jansen’s wife, Grace, and Dr Carin Buys, wife of Mr Rudi Buys, Dean of Student Affairs, volunteered to drive the programme and raise funds to address the problem. They are supported by various divisions within the university.

Students apply for the bursaries and are selected on the basis of their financial needs, good academic results, active participation in student life programmes and commitment to give something back to the community.

The raising of funds is a continuous process involving awareness campaigns, seeking of partnerships with companies and institutions and support from the general public, staff and individuals.

An agreement has been made with several food outlets/restaurants on campus who offer healthy, balanced meals to NSH students when they swipe their student cards that are funded by the programme.

At the end of the year the process is reviewed and students who still qualify are reinstated on the programme, whilst those whose circumstances have changed or are no longer in need of the bursaries, make way for new applications.

The NSH Team meets with students on a regular basis with the purpose of offering training, motivation and opportunities for personal growth and career development. Students are also expected to become involved in projects as a way of ploughing back into the community.

The goal is to expand the project annually as support for it grows.
Ms Nicky Abdinor, a clinical psychologist from Cape Town, who was born without arms and with shortened legs, provided an entertaining motivational speech at the launch. Ms Abdinor, founder of the Nicky's Drive organisation, also visited the UFS’ Unit for Students with disabilities where she delivered a talk on independence for people living with disabilities.
