Dr. Leisha Rajkumar

Leisha Rajkumar is a South African medical researcher working in diagnostic radiology, with affiliations linked to major academic hospitals in Johannesburg, including Chris Hani Baragwanath Academic Hospital. Her work is situated within clinically driven imaging research, focusing on improving diagnostic accuracy and quality standards in resource-constrained settings.

Her publications highlight expertise in thoracic imaging and infectious disease–related radiology, including quality assurance in paediatric chest radiographs for tuberculosis assessment and CT pulmonary angiography findings in HIV-infected patients. She has also contributed to prospective research on optic neuritis, integrating radiological and clinical perspectives to better characterise disease patterns in African populations.

The available body of work reflects a strong emphasis on contextualised imaging protocols, inter-reader reliability, and clinically meaningful outcomes. Although based on a limited number of publications at present, the research demonstrates a commitment to strengthening diagnostic pathways and evidence-based imaging practice in sub-Saharan Africa.
