Research Summary:

Dr. Haider's major research activities focus on abdominal and pelvic magnetic resonance imaging (MRI), with a special interest in therapeutic response assessment and functional imaging (“radiomics”) of cancer using MRI and computed tomography. He has a particular interest in prostate cancer imaging, as well as in pancreatic, renal and liver cancers.

Dr. Haider has held peer-reviewed grants from Prostate Cancer Canada, the Canadian Cancer Society Research Institute, Cancer Care Ontario and the Ontario Institute for Cancer Research (OICR) for MRI-related prostate cancer research. He holds a protected research time grant from the OICR. He is also the imaging lead on national prospective MRI trials in prostate cancer. Dr. Haider has worked on establishing guidelines for the use of multiparametric MRI (mpMRI) for prostate cancer including the Pi-Rads standard for performance and interpretation of prostate mpMRI. At Sunnybrook he leads a program in the use of mpMRI for detection, localization and image-guided biopsy of prostate cancer and is collaborating in image-guided approaches to focal prostate cancer ablation often referred to as “the male lumpectomy”.
