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

Top class musicians appointed for UFS Odeion String Quartet

The University of the Free State (UFS) has recently appointed three top class musicians for the Odeion String Quartet. The quartet, which was formed in 1991, is the only resident quartet at a South African university.

The new persons who were appointed are: Denise Sutton, first violinist and leader of the string quartet, Jeanne-Louise Moolman, alto violinist, and Sharon de Kock, second violinist. The post of cellist was recently advertised and applications can be submitted at the UFS until 29 February 2008.

The new appointments follow after three former members of the quartet retired or left Bloemfontein at more or less the same time. Michael Haller, longtime cellist of the quartet, will also be retiring at the end of 2008.

These developments means that the Odeion String Quartet will literary be brand new. It also implies that opportunities exist for learners and students to be taught by excellent new lecturers. The new players will also strengthen the Free State Symphony Orchestra to a large extent.

“The Odeion String Quartet is a flagship of the UFS and it symbolises our commitment to the arts. It also plays an important strategic role in the development of symphony orchestra music and classical music training in the Free State. This is why a real attempt was made to obtain top class musicians. We are pleased that such a strong group could be appointed,” said Prof. Frederick Fourie, Rector and Vice-Chancellor of the UFS and chairperson of the String Quartet’s management committee.
Most string quartets abroad are affiliated with a higher education institution, which enables a higher level of playing as there is more time for preparation and to study the repertoire. “We appreciate the university’s confidence in us and for the opportunity to explore the intricacies of ensemble playing. We hope that we can produce inspiring performances for our audiences and students,” said Denis Sutton, new leader of the string quartet.

Denise Sutton studied at the University of Stellenbosch (US) and obtained the degree B.Mus. with distinction. After this, she studied in Amsterdam with Theo Olof and Nap de Klijn, as well as in London. She was leader and second violinist in the Scottish Chamber Orchestra and did a successful audition for the English Chamber Orchestra. In South Africa she had a long career as concert master and leader of symphony orchestras. From 1980 she was concert master of the TRUK Orchestra for almost twenty years and from 2000 until 2005 she was member of the Johannesburg Festival Orchestra and the Chamber Orchestra of South Africa (COSA). She was also a founding member and leader of the Rosamunde String Quartet, one of the leading string quartets in the country. Denise had a very successful parttime teaching practice at the University of Pretoria (UP) and at a number of schools. She was also involved in postgraduate training. Her students include various competition winners and a number of them are playing professionally.

Jeanne-Louise Moolman studied at the UP under Prof. Alan Solomon where she obtained the B.Mus and B.Mus.Hons. degrees with distinction. She won among others the ATKV Forté and the Oude Meesters competitions and in 1985 she was the first winner of the prestigious 75th Commemorative Prize of the University of Natal. She has about twenty years experience as head alto violinist of various professional orchestras in Gauteng. Until her appointment at the UFS she was leader of the alt violinists in the Johannesburg Philharmonic Orchestra and COSA. She is an experienced chamber musician who regularly performs in various combinations with some of South Africa’s leading musicians. This includes Gerard Korsten, Phillipe Graffin, Jürgen Schwietering, the pianists Lamar Crowson and Albie van Schalkwyk, as well as clarinet player Robert Pickup. Jeanne-Louise was also a founding member of the Rosamunde String Quartet. She lectured on a part time basis at the UP and the Pro Arte Music School.

Sharon de Kock obtained the degrees B.A. Mus. and M.Mus. at the College-Conservatory of Music (CCM) of the University of Cincinnati in the United States of America (USA) in 2002 and 2004 respectively. Some of her teachers include the well-known concert violinist Chee-Yun Kim, Prof. Kurt Sassmannshaus and Piotr Milewski, all alumni of Julliard. From 2004 to 2006 she was violinist lecturer at two universities and a music conservatorium in Puebla, Mexico. She was also violin lecturer at a music school in Costa Rica and was associated with the Hugo Lambrechts Centre in Cape Town since 2007. Her orchestra participation includes among others the Opera Orchestra in Trujillo, Peru, the Sinfonica Nacional de Costa Rica in Costa Rica, as well as the Kentucky Symphony Orchestra, the Richmond Symphony Orchestra and the Dayton Philharmonic Orchestra. She also participated in the Luca Music Festival in Italy, the Grandin Music Festival in Portugal, the Pacific Music Festival in Japan and the Aspen Music Festival in the USA. Sharon performed regularly abroad as soloist and received various awards. This includes among others the CCM chamber music competition 2003 and the Baur Orchestral Competition and Heermann competition winner for violin at the CCM in 1995. In 1990 she won the first prize in the Sanlam competition.

The first official performance of the “new” Odeion String Quartet will be in May this year in Bloemfontein. Hopefully the new cellist will be appointed by this time. Members of the quartet will however perform on Friday, 1 February 2008 together with Albie van Schalkwyk and guest cellist Marian Lewin at 19:30 in the Odeion, as well as in the upcoming Spanish Music Festival held in February and March 2008. In May 2008 the quartet will participate in Zimbabwe in the Bulawayo Festival.
