Research Summary:

Dr. Sahgal’s research relates to his training and clinical expertise in spinal metastases, brain metastases and primary central nervous system tumours. He has expertise in the technical evaluation of radiation apparatus, and in developing and conducting clinical trials specific to brain radiosurgery and stereotactic body radiotherapy for spinal metastases.

Dr. Sahgal’s main interest is in fundamental technical research and development specific to MR-linac technology, Gamma Knife technology and the general application of stereotactic radiation. In line with high-precision radiotherapy treatments, Dr. Sahgal participates in the development of focal nonradiotherapeutic modalities for spine and brain tumours using photodynamic therapy, radiofrequency ablation and MRI-guided ultrasound.
