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

Call for campus review and participation into renaming and renewal of statues, signs, and symbols on UFS campuses
2016-08-25

 

The leadership of the University of the Free State (UFS) is issuing a Call for the renaming and renewal of statues, signs, and symbols on the three campuses to staff, students, and alumni.

In line with the founding statement and guidelines of the Naming Committee of Council, The Call will seek to retain the best representations of the history and identity of the UFS over more than a century, while committing to the transformation imperatives of our new democracy so that the totality of statues, signs, and symbols give credence to both the past and the future, all in line with the values of the Constitution of the Republic of South Africa.

Submissions should be made to the
SSSC between 21 July 2016 and 31 August 2016.
Proposals can be delivered to the
office of the Director: Communication and
Brand Management at Room 49,
Main Building, Bloemfontein Campus, or
via email to sssc@ufs.ac.za.

The ‘Guiding Principles’ of the Naming Committee, approved by Council on 8 March 2013, are transformation, reconciliation, excellence, distinctiveness, leadership, comprehensiveness, balance and sensitivity. The Policy of the UFS on Naming and Renaming is available here: http://bit.ly/2aeTLUz; and the Remit of the Naming Committee of the UFS is available here: http://bit.ly/29NXESC.

The Call will give special attention to creative submissions from staff, students, and alumni, such as signs and symbols that reflect our entangled past and place rival memories in critical conversation. Whatever is proposed, our commitment to the Academic Project and the Human Project remain foundations on which inspirational proposals could be based. In the end, a campus that is richly diverse, inclusive, and just in its symbolic infrastructure, would give visible meaning to the university’s commitment to social justice and reconciliation.

All submissions should be made to the Statues, Signs, and Symbols Committee (SSSC) between 21 July 2016 and 31 August 2016. Proposals could be delivered in hard copy to the office of the Director: Communication and Brand Management at Room 49, Main Building, Bloemfontein Campus or via email to sssc@ufs.ac.za.

Proposals will be reviewed by the SSSC, which is a subcommittee of the Naming Committee.

Final proposals will be submitted to Council for consideration at its final meeting of the 2016 academic year. In other words, new statues, symbols and signs – those approved by Council – will be implemented from January 2017.

Submissions could include, but are not limited to, the following: the renaming of streets and buildings; the proposal of new statues and other symbols on campus; the renewal of artwork collections; the reconfiguration of existing statues and symbols; the introduction of memorial gardens; the instatement of new galleries, sculptures, and literary collections; the establishment of prominent academic chairs or annual academic lectures in the name of illustrious figures, etc. Particular attention should be given to new buildings in the process of being built, such as residences.

Finally, it is important that the views and recommendations of all staff, students, and alumni be considered in submissions and that every campus citizen, past and present, has a sense of being able to participate fully and freely in the process.
