About

Edward W. Johnston is an interventional radiologist and clinical researcher whose work sits at the forefront of robotic-guided oncological procedures and precision biopsy techniques. Based in the United Kingdom, Johnston has made significant contributions to the adoption and validation of CT-guided robotic systems in interventional oncology, helping to pioneer their use within the UK clinical setting. His landmark 2023 comparative cohort study on robotic versus freehand CT-guided radiofrequency ablation of pulmonary metastases — now accumulating 17 citations — demonstrated meaningful advantages of robotic precision in treating small lung lesions, a finding with direct implications for patient outcomes. His 2022 work documenting the first UK experience of robotic interventional oncology (11 citations) has served as an important reference for centres seeking to implement these technologies. Johnston has also advanced the field of image-guided biopsy, developing MRI/CT fusion robotic techniques to improve tumour targeting and histological correlation (9 citations), and contributing to prostate cancer tissue research through the PEOPLE pathway. His growing body of work on robotic multiregional "smart" biopsy further underscores his commitment to characterising tumour heterogeneity, a critical challenge in modern oncological research.
