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 University of the Free State (UFS) and the Central University of Technology (CUT) united in a Student Safety Awareness March, which took place on Thursday 27 July 2017 from the UFS Bloemfontein Campus to the Bram Fischer Building.

The peaceful march had a turnout of approximately 1 500 students and staff from both institutions, led by the Student Representative Councils (SRC) from UFS and CUT. The purpose of the march was to hand over a memorandum to the Provincial Commissioner, Lieutenant General Lebeoana Tsumane, who acknowledged it on behalf of Mr Sam Mashinini, MEC for Police, Roads, and Transport in the Free State. The memorandum includes students’ demands regarding safety around student residential areas and general student safety in the city.

Prof Francis Petersen, UFS Rector and Vice-Chancellor, who – together with other members of the senior leadership group – was part of the march, says he is very impressed with the outcome of the march and the participation rate of both staff and students, as well as the joint efforts between the UFS and CUT to arrange the march.

Prof Petersen says, “There are public spaces where our students feel unsafe, and we would like the city and the province to seriously look into that and work with us to try and see if we could make those spaces safe.

A week filled with safety activities
The march was part of the Safety Week taking place from 24 to 28 July 2017, during which the UFS SRC, together with other stakeholders, took part in several activities on and off the Bloemfontein Campus. These included door-to-door visits to student homes and residences on and around campus, awareness campaigns at all the gates of the campus, and a Safety Dialogue held on 26 July 2017 at the Equitas Auditorium on campus.

The aim of the Safety Week was to focus on informing, educating, and encouraging students as well as the Mangaung community at large, to work together in creating a safe environment for students. The week started with the roll-out of an awareness campaign titled Reach Out, which was set to bring students and the community of Mangaung together to help decrease the number of violent crimes faced by students off campus. The communication plan included safety messages, using outdoor billboards, posters on lampposts around the residential student areas, local community radio stations, campus media, and the university’s social media platforms.

Accreditation of off-campus accommodation service providers
Over and above the Safety Week and safety awareness march, the university has initiated a number of other projects as part of its student safety strategy. This includes a process to accredit off-campus accommodation service providers in Bloemfontein who provide accommodation to students. The decision to accredit these service providers comes from a concern by the university management about the safety of students and the conditions under which some of our students live in off-campus accommodation. The accreditation process entails a list of primary requirements, drafted with the cognisance of the Mangaung Metropolitan Municipality and the SRC, in terms of off-campus accommodation to which private providers must adhere in order to be accredited by the university. The requirements are in line with the Policy on the Minimum Norms and Standards for Student Housing at Public Universities (Government Gazette 39238, dated 29 September 2015).

Transport to and from campus
Another project to be initiated on 31 July 2017 is a transport pilot project with Interstate Bus Lines to assist students with transport and access to the Bloemfontein Campus. The route includes various stops in the areas surrounding the campus, as well as a hop-on/hop-off route within the campus.
