Dr Osayande Evbuomwan, Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine at the University of the Free State (UFS), received the first clinical PhD in nuclear medicine completed at the UFS at the April graduation ceremonies.

Dr Osayande Evbuomwan, Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine, Faculty of Health Sciences, at the University of the Free State (UFS), graduated with the first clinical PhD in nuclear medicine completed at the UFS.

He graduated on Thursday (18 April 2024) at the university’s autumn graduation ceremonies when the Faculty of Health Sciences conferred degrees on its graduation class of 2024.

Dr Evbuomwan, the man behind his department using Lutetium 177 PSMA (Lu-177 PSMA) therapy and now Actinium 225 PSMA therapy to treatment metastatic castrate resistant prostate cancer (MCRPC) – an advanced stage prostate cancer, said his PhD is about using a special radiopharmaceutical called Technetium 99m ECDG to detect active disease in the joints of patients with rheumatoid arthritis (RA).

More opportunities for similar degrees

This research has won him the Society of Nuclear Medicine and Molecular Imaging (SNMMI) International Best Abstract Award for South Africa during last year’s SNMMI 2023 Annual Meeting in the US.

“I am very grateful, and at the same time, proud about this achievement (his PhD). This qualification will definitely give more opportunities for further similar degrees at the department. So yes, I feel very happy and fulfilled.

“Rheumatoid arthritis is a debilitating disease with associated morbidity that can lead to serious joint deformity and destruction. The need for an investigation with a very high diagnostic accuracy in detecting active disease is needed, especially in the detection of subclinical disease. Few prior studies in the literature had shown promising results with Tc 99m ECDG imaging in this regard. So, we decided to conduct a proper prospective study to test this hypothesis,” says Dr Evbuomwan.

This research, he explains, was also aimed at finding out if the new nuclear medicine radiopharmaceutical for the identification of active disease in patients with rheumatoid arthritis can also offer prognostic information. This aspect of the study concluded that this particular radiopharmaceutical (Tc – 99m ECDG) is highly sensitive in identifying synovitis (inflammation of the membrane that protects joints) and is capable of offering prognostic information in patients with rheumatoid arthritis.

This was the first prospective study to assess the prognostic value of this radiopharmaceutical in patients with rheumatoid arthritis, Dr Evbuomwan says.

Researching theranostics in the future

According to him, he had a smooth journey to completing his PhD – something he contributes to support from the fantastic team of three supervisors, the assistant who prepared the radiopharmaceutical, the rheumatology department, the radiographers and nurses at the Department of Nuclear Medicine, and most importantly, his wife and two daughters.

His passion for research, growth and the practice of nuclear medicine were his major motivators on this journey.

Dr Evbuomwan is currently looking at the possibility of starting research on theranostics. The only stumbling block for now, he says, is that the department still does not have a PET/CT camera, as this is very vital in today’s nuclear medicine practice. However, together with the Free State Department of Health, they are working hard to secure one.

“I now want to focus on nuclear medicine therapy and its promotion. This includes both imaging and treatment (theranostics) of certain cancers, most especially prostate cancer, neuroendocrine neoplasms, thyroid cancers and the neuroectodermal tumours. I also want to focus on being involved with the training of more registrars at the department of nuclear medicine and increasing the awareness of nuclear medicine amongst colleagues in the Free State,” says Dr Evbuomwan about his future plans.

Meet our Council: Loraine Roux – a proud Kovsie ambassador
2016-07-01

“I strive to represent the alumni
actively as an interest group,
and to help build the university
through sound business principles.”

Loraine Roux (née Kriek), former President of the Student Representative Council, was elected to the Council of the University of the Free State (UFS) in 2012. This former Kovsie made her mark at the UFS. Many staff members and former students will remember her as the beautiful brainbox, who achieved success in so many different areas of student life and humanity.

Loraine’s studies


Her journey as a Kovsie started as finalist in the prestigious Matriculant of the Year competition. Later, she obtained a Bachelor’s degree in Consumer Science at the UFS. Loraine, a born leader, was also Prime of Soetdoring residence, and remains the only student in the history of the university to be chosen as SRC President, Rag Queen, and Dux student in the same year.

After university

The Kriek family are all stalwart former Kovsies, with three generations – Loraine, her late grandfather Johan Kriek, and godparents, Rhyno and Mariette Kriek – having served on the Student Representative Council. So, it is no surprise that a leading firm like Deloitte & Touche noticed Loraine’s unique talent and leadership skills, and snatched her up for their CEO Bootcamp immediately after university.

Serving on the UFS Council


Currently, she is part of the team that is extending Deloitte & Touche’s ethical and fraud prevention services across Africa and Europe. She also uses her expertise and experience in risk management, ethical practice, and good corporate governance for her role as UFS councillor. As part of her duties as Alumni representative in the Council, she serves on the Naming Committee, as well as on the Audit and Risk Committee.

“It is a great privilege for me to serve on the Council, but it is also a great responsibility,” she says. “I strive to represent the alumni actively as an interest group, and to help build the university through sound business principles.”

Loraine married Gabriel Roux in 2014, and the couple live in Stellenbosch.
