Nuclear medicine plays an important role in the clinic, both diagnosis and treatment. In addition to the conventional nuclear medicine, positron emission tomography is available in a PET Center, located right next to the main hospital. For the future, I anticipate that nuclear medicine makes more impact on the clinic and the research.

Research Project

Blood flow analysis for the brain

We collaborate with neurosurgeons, neurologists, and psychiatrists for the blood flow analysis in the brain using various radioisotopes, including QSPECT method with 123I-IMP, 3D-SSP analysis, eZIS analysis with 99mTc-ECD, and Dat scan with I-ioflupane.

131I treatment

131I treatment has been performed for over 3 decades in our department. Treatment effect and survival are now under studied. The relationship between the uptake in 123I scintigraphy and treatment effect by 131I is interesting topic. Recently, we have started using 89Sr and 223Ra for the treatment of bone metastases.

Positron emission tomography (PET)

FDG uptake in a tumor/tissue on PET can be a good biomarker to indicate patients’ outcome. We have been studying the usefulness/efficacy of PET in the clinics. Especially, in the patients who underwent stereotactic body radiotherapy for lung cancers.
