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

Dean of the Faculty of Law delivers farewell lecture
2013-12-04

Prof Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS), delivered his farewell lecture during an event attended by distinguished guests from law circles in Bloemfontein, staff from the faculty, as well as family and friends.

The topic of his farewell lecture was: From leonine to universal partnerships. This theme was also the focus of his inaugural lecture and his later research. “It was a privilege to have been part of the development of universal partnership law,” Prof Henning said.

During the event, Prof Henning was honoured by colleagues, as well as members of the law profession, for his contribution to the academy. Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, thanked Prof Henning for his part in preparing a new generation of academics for the future.

Prof Elizabeth Snyman-Van Deventer from the Department of Mercantile Law, described Prof Henning as someone with an excellent knowledge of history, especially with regard to the Anglo-Boer War and the World Wars. “He is also one of only a few academics of which four postgraduate students became professors. He has lots of empathy with other people and, despite his long list of academic achievements, he is a very humble man. Two of his outstanding characteristics are his humanity and his modesty,” said Prof Snyman-Van Deventer.

Judge Faan Hancke, former chairperson of the UFS Council and Judge of the Supreme Court, said Prof Henning is a multi-faceted person. “He is an incredible academic who has published widely and is the author of several textbooks. He is also editor of a number of journals and serves on the editorial board of several publications. I have great admiration for his academic excellence and his absolute knowledge of partnership law. He is the best in South Africa and is also highly regarded internationally in this aspect of the law (he was, among others, director of the Centre for Comparative Partnership and Company Law at the Institute of Advanced Legal Studies of the University of London). He is the ideal academic, who has achieved the highest rating in his specialist field of Mercantile Law in South Africa, namely a B1 received in 2012, and he is an excellent dean,” Judge Hancke said.

Prof Henning has a long association with the UFS. In 1968 he reported as a first-year student. Later, in 1974, he was appointed in the Department of Mercantile Law on a temporary basis. In 1998 he was appointed as Dean of the Faculty of Law. Some of the highlights in his career include his appointment as African representative of CIDOEC, Jesus College, Cambridge, and becoming the first South African being awarded an honorary fellowship to the Society of Advanced Legal Studies in Brittain, as well as the American Order of the Coif.

Prof Henning will continue his partnership with the university in 2014, acting as dean and continuing his research.
