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

Minister Jeff Radebe commends UFS for measures taken to address racial prejudices

Minister Jeff Radebe lecture: YouTube video

Mr Jeff Radebe, Minister of Justice and Constitutional Development, last night delivered a lecture in the Prestige series of the Dean: Faculty of Law, at the Bloemfontein Campus of the University of the Free State (UFS).

In a packed hall with, among others, university students, staff and members of the judicial system, Minister Radebe said that many other academic institutions should look to the UFS when they deal with the challenges of racism in its various manifestations in their midst. “I commend the university for taking drastic measures to address the challenges of racial prejudices in its own backyard,” he said.

“Government can and must provide leadership, but it is the collective efforts of all our people that will ensure that we bridge the racial and historical divides that stand in contrast to our noble virtues as entailed in the Constitution,” the Minister said.

On the topic “Access to Justice” the Minister said that the Department of Justice and Constitutional Development has channelled more than 80% of its nearly R16 billion budget to the Access to Justice programme.

Minister Radebe talked about the reintroduction of the Sexual Offences Courts, which attests to the unrelenting resolve to eliminate the scourge of gender-based violence. “Fifty-seven of the department’s Regional Courts are being upgraded to operate as dedicated Sexual Offences courts during the 2013/2014 financial year. We believe that these sexual offences courts will help address the growing challenge of sexual offences in the country, particularly against vulnerable groups.”

The Minister also pleaded with law teachers to avail themselves to preside in the courts in our country to complement the decreasing number of presiding officers that are drawn from the attorneys’ and advocates’ profession. These services are normally rendered by the Commissioners pro bono as part of an endeavour to bring justice to all the people, including the poor.

A challenge that the UFS could help resolve,is the transformation of the legal profession. “We need to increase the number of Law students and in turn increase the number of attorneys and advocates in the pool from which we derive candidate judges,” Mr Radebe said.

The Legal Practice Bill and the transformation of the State Legal Service are the most important initiatives underway by which the Institutions of Higher Learning will make a contribution. “The Bill seeks to establish a single regulatory structure, which will be responsible for setting the norms and standards for all legal practitioners. Members of the public, as primary beneficiaries of the legal profession, will also be represented in this structure. Other important objectives of the Bill are the removal of barriers of entry to the profession for young law graduates who aspire to pursue a legal career, and the introduction of measures aimed at ensuring that fees chargeable for legal services are reasonable and within reach of ordinary citizens,” he said.

The Minister concluded: “Our courts must reflect both the race and gender demographics of our country and so must the university communities in their various capacities as a microcosm of the society we seek to build.”
