Biography and Research Information
OverviewAI-generated summary
R.J. Megahed's research focuses on the application of radiation therapy across various oncological diagnoses. Publications include studies on decreasing utilization of postoperative radiation therapy for medullary thyroid cancer, and the use of spatially fractionated radiation therapy for head and neck malignancies. Megahed has investigated liver-sparing total body irradiation with helical tomotherapy for relapsed acute lymphoblastic leukemia, and interstitial brachytherapy for soft tissue sarcomas, examining outcomes and patterns of failure. Further work explores intensity-modulated proton therapy to mitigate inter-fractional variations and the potential of dual-energy spectral CT quantitative parameters for response assessment in head and neck cancer treatment. Additionally, research includes utilizing in-room cone-beam CT to streamline gynecological brachytherapy workflow. Megahed has 17 publications and an h-index of 2, with recent scholarly activity indicating ongoing work in the field.
