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

Message of appreciation from the UFS acting Vice-Chancellor and Rector: Prof Nicky Morgan

2017-01-04

Dear Colleagues, Students, Parents/Guardians, Alumni, and Friends of the university

The University of the Free State (UFS) successfully completed the 2016 academic year, with the official examination ending on 14 December 2016. We have also completed the last of our graduation ceremonies, and are now preparing to accommodate the additional and ad hoc examinations in the coming weeks.

This comes after the university has successfully readjusted its academic programme in October 2016, subsequent to the disruption of activities and programmes for almost a month. All of this could not have happened without the extraordinary support and dedication of the staff and majority of the students at the UFS.

I would like to thank all our staff, parents/guardians, alumni, and friends of the UFS for the role they played during these challenging months in order to ensure that we could end the academic year successfully. If it was not for your understanding and uncompromising support, we would not have been able to complete the curricula, continue with the exams, and end the year in this way.

However, we all know that this was not an easy task. The sheer dedication and drive of our academic staff to adapt the mode of teaching and assessment of modules must be applauded, as it took courage and perseverance. Not only did they manage to complete the curricula, they also managed to do the assessment almost completely online. The incredible role of our administrative and support staff – including our security personnel – should also be acknowledged with deep appreciation.

This has been a learning experience for all, which has provided us with a solid base for academic recovery in the future.

During its quarterly meeting on 2 December 2016, the UFS Council expressed appreciation to all staff, students, and the university management for the successful completion of the 2016 academic year.

To all our alumni and donors who continued to support the UFS this year – thank you for your commitment, loyalty, and continued contribution.

Looking forward to 2017
The UFS announced on 7 December 2016 that it will be increasing tuition and housing and residence fees for 2017 by 8%. The approved increase in fees is in line with the recommendations by the Minister of Higher Education and Training, Dr Blade Nzimande, on 19 September 2016. The increases were approved by the UFS Council on 2 December 2016, with the understanding that it would be paid by the Department of Higher Education and Training by means of the fee adjustment grant for qualifying students with a combined family income of not more than R600 000 per annum.

The university management is aware of the economic realities in South Africa, as well as the financial pressure households are experiencing. The long-term financial sustainability of the UFS, as well as the financial constraints which impact teaching and learning, research, and community service, continues to remain of utmost importance to the Council and to the senior leadership of the UFS.

The university management stated its pro-poor approach to student funding on several occasions; that academically deserving students from poor and working class families should receive substantial financial support. For this reason – also because it does not place a burden on poor and working-class families – an increase in tuition fees aligned with the DHET proposal was submitted to Council for approval. The presidents of the Bloemfontein and Qwaqwa Campus Student Representative Councils were present and participated in the discussion on fees – also when Council approved the increase.

I am thankful to report that more applications for admission were received for 2017 (42 568) in comparison to 2016 (29 284), and we are excited to welcome first-year students to our campuses in January 2017. See 2017 calendar of events and information.

The necessary safety measures have been taken and contingency plans are in place when students return in 2017. The university management will continue to work with the South African Police Service to ensure stability on the campuses and the uninterrupted continuance of the Academic Project.

In conclusion, I would like to wish you a restful and safe Festive Season. Thank you once again for your crucial role in making the University of the Free State still one of the universities of choice in the country.

Best regards

Prof Nicky Morgan
Acting Vice-Chancellor and Rector
University of the Free State
