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

Engaging men to act against gender-based violence in the Southern African context.

This was the theme of the second International Leah Tutu Symposium, hosted by the Gender Initiative of Trauma, Forgiveness and Reconciliation Studies of the University of the Free State (UFS) on Tuesday 24 February 2015.

What does it mean to be man? How can men become active in the fight against gender-based violence? And when does one say: enough is enough? Questions like these set the tone as highly-respected individuals such as Dr Mamphela Ramphele, Prof Rob Morrell, Lisa Vetten and Andy Kawa took to the stage in the Odeion on the Bloemfontein Campus.

Leah Tutu
Unfortunately, Mrs Leah Tutu could not attend this year’s event, but she still managed to send sparks of wit and insight into the auditorium. In her video message, Mrs Tutu referred to the fact that our country has “consigned discriminatory legislation to the rubbish bin of the past”, but we continue to inhabit a divided society.

“We have a constitution and bill of rights that should have sounded the death knell for patriarchy. But women are unsafe across the land,” Mrs Tutu said. “Our freedom cost too much to be left out in the rain,” she urged.

Ndiyindoda! Yes, you are a man
In Dr Ramphele’s keynote address, “Ndiyindoda! Yes, you are a man”, she scrutinised the dominant masculinity model that has supported an alpha-male mentality for millennia. A mentality that celebrates dominance, power and control – where the winner takes it all. How then, can we expect our young boys to embrace the value system of a human rights culture?

“Gender equality is at the heart of our constitutional democratic values. Yet, our society continues to privilege and celebrate the alpha male as a masculinity model,” Dr Ramphele said. This dissonance can only produce conflict and violence.

We encourage our young men to be gentle, communicative, caring people who show their emotions. And when they do, what do we as women do? Do we encourage them?

“Or do we join those who call them wimps, moffies, sissies? How do we respond when they are ridiculed?” Dr Ramphele asked. Are we, as mothers, fathers and grandparents willing to socialise our children to acknowledge a diversity of masculinities as equally valid in our society?

The new man and the new woman of the 21st century need to be liberated from the conflict-ridden dominant masculinity model. They need to be able to shape their identity in line with a value system of human rights as enshrined in our constitution.

Perhaps Dr Ramphele’s message could be summed up by one sentence: You cannot find Ubuntu in a culture of dominance.
