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

UFS changes format of graduation ceremony
2011-04-17

 

The highest number of qualifications in the history of the University of the Free State (UFS) will be awarded at the autumn diploma and graduation ceremony from 9-11 May 2011, which will be held in the Callie Human Centre on our Main Campus in Bloemfontein.

From this year, the format of the ceremony will change to make it more visible to students and the public. For the first time, all the doctoral and master’s degrees from each respective faculty will be conferred during one ceremony on 11 May 2011, instead of each faculty handling these qualifications individually. Another change in the format is that the procession will gather on the Red Square in front of the Main Building and move to the Callie Human Centre from there. Both academic staff and graduands will partake in the procession.

A total of 3 674 qualifications will be conferred during this year’s graduation ceremony, including 629 diplomas, 2 613 Bachelors and honours degrees, 372 master’s degrees and 58 doctorates.

An honorary doctorate in Drama and Theatre Arts will also be awarded to theatre stalwart Mr Pieter Fourie. He is one of the most acclaimed Afrikaans playwrights in South Africa and probably the only person to have left his mark as an actor, director, artistic director and writer.

Mr Fourie was awarded the Gerhard Beukes prize for drama , was honoured for his contribution to the arts by the South African Academy for Science and Arts and was appointed as trustee of the Arts and Culture Trust of the State President in 1997. He has also served as a committee member of the South African Academy for Science and Arts.

Mr. Fourie has also been the proud recipient of the Hertzog prize for drama, two FNB-Vita awards and a Fleur Du Cap award.
 

The full programme for the respective ceremonies is as follows:

  • Monday, 9 May 2011:

At 08:30, certificates and diplomas, excluding PGED and PGES, will be awarded to graduates from the Faculty of Education and at 12:00 PGED, PGED and B and honours degrees will be awarded to students from the same faculty. At 15:30 on the same day, certificates and B and honours degrees will be awarded to students in the Faculty of the Humanities.

At 19:00, the Faculties of Education, the Humanities and Economic and Management Sciences will have their prize-giving ceremonies for outstanding achievers.

  • Tuesday, 10 May 2011:

At 08:30, students in the Faculty of Economic and Management Sciences will graduate and at and 12:00 the Faculty of Natural and Agricultural Science will join them. This includes students in BML, B.Admin., B.Pub. and related honours degrees. At 15:30, 503 students from the Faculty of Natural and Agricultural Sciences will receive their certificates, diplomas and B and honours degrees.

At 19:00, the Faculties of Health Sciences, Natural and Agriculture Sciences, Law and Theology will have their prize-giving ceremonies.

  • Wednesday, 11 May 2011:

The Faculty of Health Sciences, the Faculty of Law and the Faculty of Theology will be awarding their certificates, diplomas and B and honours degrees at 08:30. At 12:00, all faculties will award a total of 372 master’s degrees and at 15:30 a total of 58 doctorates will be conferred.

The Chancellor’s Dinner will take place in the Centenary Complex on the Main Campus of the UFS at 19:00.

The graduation ceremony of our Qwaqwa Campus will take place in the Rolihlahla Mandela Hall on the Qwaqwa Campus on 7 May 2011 at 10:00. All the faculties at this campus will confer their degrees, certificates and diplomas at this ceremony.
