Professional Overview
In 2016, Dr. Segwe co-founded the Centre of Medical Imaging (CMI) at Life Carstenhof Hospital in Gauteng – at the time, a hospital still running an analogue radiology department, while doctors across the road already had digital imaging.
When she and her co-founder approached funders and equipment vendors, one vendor refused to even quote them, certain the two newly qualified specialists would “sink their money and flush it down the toilet.” Where others saw risk, Dr. Segwe saw possibility. There wasn’t even fibre reaching the hospital – so she saw through the municipal approvals and trenching required to bring connectivity in herself, infrastructure the hospital still relies on today for its Wi-Fi and ward systems.
That determination transformed an ambitious vision into reality: she invested more than R36 million in advanced diagnostic technology, built a full modality suite under one roof – from X-ray and CT to cardiac imaging and nuclear medicine – and grew CMI into one of South Africa’s leading advanced radiology practices, recognised for its rapid responsiveness and trusted partnerships with referring doctors.
Her commitment to innovation doesn’t stop at her own doors. Dr. Segwe believes Africa’s diagnostic future depends on more than adopting the world’s technology: it depends on Africa producing its own evidence, not only importing findings built on other populations. She is currently developing plans for locally-led diagnostic research, beginning with a proposed CT cardiac scan study stratified by race and disease – a first step toward ensuring the evidence shaping African healthcare actually reflects the patients it serves.
"We never stop learning, questioning, and exploring better ways to improve lives."

On artificial intelligence, her view is clear-eyed rather than either fearful or uncritical: change, she says, will happen to you, through you, or with you – and she’d rather help shape it than resist it. At CMI, AI already supports processes like cardiac imaging analysis, but every result is reviewed and, where necessary, corrected by a radiologist – a distinction she considers essential, not incidental, particularly while questions of legal accountability in AI-assisted diagnosis remain unresolved.
Today, that vision continues to grow. She is focused on strengthening CMI’s stroke centre, investing in PET-CT technology, and expanding the practice nationally – with Mahikeng firmly in her sights for its next chapter. Longer term, her ambition reaches further still: to help make Africa the place the rest of the world looks to for diagnostic excellence, not the market that borrows it.
That same drive shows up in her own development. She recently completed advanced neuroradiology training with the European Society of Neuroradiology in Valencia, attended the Radiological Society of North America’s annual meeting in Chicago, and was invited to participate in a regional International Atomic Energy Agency conference in Nairobi. Colleagues describe her as a leader who uplifts, supports and inspires others through kindness, resilience and purpose.
Her influence extends well beyond her own practice. Accredited by the HPCSA to train radiography students from the University of Pretoria and the University of Johannesburg, she is helping develop the next generation of diagnostic healthcare professionals whose expertise will strengthen diagnostic care across Africa for decades to come.
Her leadership has been recognised nationally. In 2026, Dr. Segwe was nominated for the Standard Bank Top Women Awards as “Top Women Leader in Professional and Support Services,” while Centre of Medical Imaging was recognised alongside multinational organisations, receiving nominations for “Top Woman Owned Business SMME” and “Top Women Business in Healthcare and Pharmaceutical.”
Whether speaking on innovation, leadership, artificial intelligence, access or patient-centred care, Dr. Segwe continues to champion a future where technology and humanity work hand in hand – one measured not only by better tools, but by the lives, and the futures, they change.
