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 Odeion School of Music (OSM) launched

2011-09-15

The University of the Free State’s (UFS) Odeion School of Music will be launched at the first Dean’s Concert in the Odeion on the Bloemfontein Campus on Friday, 16 September 2011.

The former Department of Music, in the Faculty of Humanities, has been transformed and will henceforth be known as the Odeion School of Music (OSM). This follows in the path of the corporate transition currently taking place at the university, which aims to reflect the progressive and dynamic striving towards excellence, as endorsed by the UFS Vice-Chancellor and Rector, Prof. Jonathan Jansen, and his management group.

Two years ago the faculty formulated a new mission with the aim to become an international faculty of excellence. An important component of it has been to create a pro-active marketing strategy and policy towards internationalisation and curriculum development.

The name Odeion School of Music portrays not only an excellent asset in the Free State, but also nationally and internationally. The school’s new name bears the respected Odeion brand and a number of successful and respected ensembles operate under this brand. These include the acclaimed residential Odeion String Quartet, as well as the Music Department’s student ensembles, the Junior Odeion String Quartet, the Odeion Sinfonia, and the Odeion Choir.

According to Prof. Nicol Viljoen, the Chairperson of the OSM, the name change was motivated by the following objectives:

The idea of a school within the Faculty of Humanities not only reflects an academic profile that does justice to the intention of the Department to reposition itself, but also simulates the current identity of the unit. This encompasses diverse thematic entities not only from an academic perspective, but also from a community and cultural perspective. The unit does this through providing services, which include arts entertainment, the provision of facilities, as well as a strong emphasis on community development.
With regard to an international perspective, it provides attractive possibilities not only from the perspective of a marketing and publicity profile, but also with regard to the identity of the unit.
Hypothetically the new name allows more flexibility to complement the profile with reference to newly anticipated developments. These include the application of prestigious international experts as artistic fellows, membership to progressive European, jointly developed degree programmes and curriculum development initiatives, the founding of a chair in Orchestra Conducting, a master’s degree in Arts Management, as well as the incorporation of bio-kinetics in the teaching methodologies of performance practice, to name but a few.
From a management perspective it could also consolidate the perspective of scarce skill specialisation.
To give momentum to the establishment of the OSM, Mr Marius Coetzee was appointed as Innovation Manager. He is a former Project Manager of the European Degree in International Music Management – a joint degree initiative between three Universities from Norway, the Netherlands and Finland, funded by the EU in Brussels. His aim will be to develop and investigate aspects such as internationalisation, marketing, pro-active recruitment strategies, curriculum development and innovative teaching methodologies.

Mr Coetzee said music conservatories, from both European and American perspectives are managed and maintained as highly successful and substantial brands. From the European perspective some examples include the Sibelius Academy in Helsinki (Finland), the Liszt Academy in Budapest (Hungary), the Grieg Academy in Bergen (Norway) and the former Sweelinck Academy in Amsterdam (Netherlands). Similar to the South African milieu, the majority of music conservatories in the USA and Canada are resident within an academic university.

However, unlike the South African reality, the majority of these institutions have a value-added identity portrayed by a specific name. Such an example is the renowned Peabody Conservatory of the University of Baltimore or the Jacobs School of Music at the Indiana University Bloomington, to name but a few.

The Dean’s Concert will highlight performances of students in the school. The concert will probably become a regular event in future Spring Music Festivals.
