About

Dr. Yoshiharu Ohno is a pioneering radiologist whose work centers on advancing oncologic imaging, particularly through ultra-high-resolution computed tomography (UHR-CT) and functional MRI techniques. His major contributions include developing intraoperative navigation systems that integrate UHR-CT with robot-assisted partial nephrectomy, dramatically improving surgical precision and renal function preservation. In a landmark 2022 study analyzing 323 patients, Ohno demonstrated that UHR-CT-guided navigation significantly enhances perioperative outcomes compared to conventional area-detector CT, establishing a new standard for nephron-sparing surgery. His research has garnered over 5,000 citations, reflecting its profound impact on urologic oncology and interventional radiology. Beyond nephrectomy, Ohno has pioneered the use of dynamic contrast-enhanced MRI and dual-energy CT for pulmonary nodule characterization, achieving diagnostic accuracies exceeding 90% in distinguishing malignant from benign lesions. His innovative work on artificial intelligence-driven image reconstruction has reduced radiation doses by 40% while maintaining diagnostic quality, earning him the Radiological Society of North America’s Outstanding Researcher Award. Ohno’s translational approach—bridging cutting-edge imaging technology with real-time surgical guidance—continues to redefine precision medicine in oncology.
