About Dr. Kappadath
S. Cheenu Kappadath, Ph.D., is an Associate Professor in the Department of Imaging Physics. He is a board-certified and licensed medical physicist with specialties in Nuclear Medicine Physics and Instrumentation (ABSNM) and Diagnostic Radiologic Physics (ABR). He provides clinical physics support for the Departments of Nuclear Medicine and Diagnostic Radiology in the Division of Diagnostic Imaging. He is the Program Director for Imaging Physics Network Services and oversees clinical Imaging Physics operations at institutions within the MD Anderson Cancer Network as well as other satellite and regional care facilities.
He is actively involved in a variety of funded research projects in SPECT/CT, PET/CT, and CT and is the recipient of grants from NIH and industry. Topics of research focus include liver-directed Yttrium-90 microsphere therapy, molecular breast imaging, quantitative imaging with SPECT, PET, and CT; and patient-specific voxel dosimetry. Dr. Kappadath also holds a joint Associate Faculty appointment at The University of Texas Graduate School of Biomedical Sciences in Houston where he serves as an instructor in various courses and advisor to medical physics graduate students. Dr. Kappadath is an active member of several professional medical physics societies such as the AAPM, SNMMI, and ACR. More recently, his research has received the Arthur Weis Award in Radiation Dosimetry and Safety from the Society of Nuclear Medicine and Molecular Imaging (SNMMI).

His research interests are focused on Nuclear Medicine physics with specific emphasis on developing quantitative imaging to aid in the diagnosis and managements of cancer patients. Areas of specialization include:
· Liver-directed Yttrium-90 microsphere therapy
· Molecular breast imaging (MBI)
· Quantitative imaging with SPECT/CT, PET/CT, and DE-CT
· Novel algorithms for patient-specific voxel dosimetry
A strong interest lies in improving all aspects of liver-directed Yttrium-90 microsphere therapy from improving patient imaging for therapy planning to quantifying post-therapy imaging to measure tumor dose and evaluate response. His research lab is looking at novel algorithms for patient-specific voxel dosimetry and its application to determine the tumor dose-response and toxicities following Yttrium-90 microsphere therapy. Research is also conducted in quantifying radionuclide uptake in breast cancers with MBI and assessing its capability as an indicator to tumor response following chemotherapy.
