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

The African Student Affairs Conference (ASAC), which took place on our Main Campus last week, was a major success, with two days of lectures and discussions and two pleasant social gatherings, where delegates had the opportunity to get to know each other.

The conference, hosted on African soil for the first time, and co-hosted by the University of the Western Cape (UWC), started on Wednesday 18 May 2011 with an informal welcoming session. Delegates got to meet each other and Mr Rudi Buys, UFS Dean of Student Affairs, explained the meaning of South African words like "kuier" and "lekker'.

The official start of events took place on Thursday 19 May 2011, in the Reitz Hall in our Centenary Complex. The conference was attended by delegates from universities across the continent and aimed to place the focus on issues relating to student affairs in an African context.

Delegates shared and exchanged strategies, ideas and resources, and discussed issues related to the work of student affairs professionals. The conference hoped to promote an exchange of best practice and assist attendees in identifying successful programmes.

Among the topics discussed on the first day, were “Constructing Post-Conflict Democracy on campus: a case study of transformation of student governance and political engagement as post-conflict intervention”, by Mr. Buys, and a discussion on ways in which social and online media can be used to ease the challenges of student interaction, development and support, by Ms Birgit Schreiber, Director of the Centre for Student Support Services at UWC.

A panel discussion, led by Mr Buys and several members of our Interim Student Council (ISC), discussed the specific challenges faced at the UFS.  The importance of buy-in from role-players in decisions taken by University management in order to ensure their success, was discussed, using the UFS and our recent changes as an example.

The successful integration of residences on campus inevitably came under the spotlight and the recently resolved Reitz-saga was named as a catalyst in getting students less apathetic and more involved in attempts at creating racial and social harmony.

Dr Christina Lunceford, Assistant-Director of the Centre for Research on Educational Access and Leadership at California State University, presented a paper entitled A National Approach to Building Capacity in Student Affairs in South African Higher Education.

She commented on the fact that there is little or no philosophical framework or explicit theory that informs practice of student services in South Africa.

According to Dr Lunceford, student development should be a key concern for every department or unit within student services and emphasized the need for a centralized student development unit at each university.
She also touched on the need for institutions to implement support from international student affairs professional associations, professional development for student affairs practitioners, the utilization of technology to support professionals in the field, and working with international partners to explore future opportunities, as ways in which student affairs can be used to drive performance and change at universities.

The conference continued in the Scaena theatre on Friday 20 May 2011, with presentations by Dr Augustinah Duyileme, Dean of Student Affairs at Adekunle Ajasin University in Nigeria, and Prof. Bobby Mandew, Executive Director of Student Affairs at the University of Johannesburg (UJ).

Dr Duyileme presented a paper on the challenges faced by Nigerian universities with regard to student conflict and protests, which often turn violent, and how such violence can be curbed through proper planning and management.

Prof. Mandew presented a very well-received presentation on UJ’s successful off-campus housing initiative, which involves home-owners and business owners in the areas surrounding their campuses.

Their approach demonstrated how proper planning can prevent problems associated with over-population in private homes and conflict with neighbours of the university, usually related to an influx of students into residential neighbourhoods.

This problem is faced by many universities, as more and more students flock to universities on the continent and campus residents cannot accommodate them.

The conference came to a close on Friday, with most delegates agreeing that the exchange of knowledge which took place was extremely valuable.

Ms Deborah Lahlan, of Nigeria, said: “This is an important conference for Africa and it should become a regular event.”
