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 breakthrough on SRC
2005-06-10

The Council of the University of the Free State (UFS) today unanimously approved the establishment of a Central Student Representative Council (CSRC)  to ensure the democratic participation of students at its three campuses in the governance of the university.

In a major breakthrough and transformation step for student governance, the Central SRC will include representatives of the main campus in Bloemfontein, the Vista campus and the Qwaqwa campus of the UFS.

The establishment of the Central SRC follows the incorporation of the Qwaqwa campus into the UFS in January 2003 and the incorporation of the Vista campus in Bloemfontein into the UFS in January 2004.

According to Dr Ezekiel Moraka, Vice-Rector: Student Affairs, today’s decision of Council is the result of a lengthy, negotiated agreement between the three campuses. Independent experts facilitated part of the process.

With the establishment of a Central SRC, the UFS has adopted a federal student governance model whereby the CSRC is the highest representative student body on matters of common concern for all students.

However, the three campuses of the UFS will retain autonomous SRC structures for each campus with powers and responsibilities for matters affecting the particular campus.

This arrangement will be reviewed after a year to make allowance for the phasing out of students at the Vista campus, as was agreed in the negotiations preceding the incorporation of that campus into the UFS.

The central SRC will have a maximum of 12 members made up of members of the campus SRCs, including the presidents of these three SRCs. In total, the main campus will have 5 representatives, the Qwaqwa campus will have 4 representatives and the Vista campus will have 3 representatives.

From these 12 members a central SRC president will be chosen on a quarterly basis to represent the general student body at Executive Management, Senate and Council.

In another key decision and significant step forward affecting student governance, the Council also approved amendments the constitution of the Student Representative Council (SRC) of the main campus.  These amendments were the results of deliberations of student organizations, the SRC and the Student Parliament of the UFS main campus.

The amendments to the constitution of the main campus SRC determines that nine of the 18 SRC members must be elected by means of proportional representation and nine on the basis of an individual, first-past-the-post election.

This decision comes in the wake of calls by certain student organizations on main campus for proportional representation to be included as a means of electing student representatives.

The following portfolios of the main campus SRC will be contested by individual candidates on the basis of first past the post:

  • president
  • secretary
  • academic affairs
  • legal and constitutional affairs
  • student development
  • arts and culture
  • men’s internal liaison
  • ladies internal liaison
  • media, marketing and liaison

The following nine portfolios will be contested by affiliated organizations on a proportional representation basis.

  • two vice-presidents
  • treasurerdialogue and associations
  • transformation
  • campus affairs and recreation
  • sport
  • international affairs
  • community service

It also is a breakthrough to have all constitutional changes processed and approved at the June meeting of the Council, with all relevant student organizations having been part of the process and accepting the outcome of the process.

According to the chairperson of the UFS Council, Judge Faan Hancke, today’s unanimous decisions on student governance are an indication of how all UFS stakeholders represented in Council are committed to finding win-win solutions in the interest of the university.

“Once again the UFS has reached another milestone in its transformation and has shown the rest of the country that we are pioneers in the field of reaching intelligent solutions to complex situations,” Judge Hancke said.

According to Dr Moraka, the central SRC constitution will come into effect from the start of the second semester this year.
