Radionuclide therapies available at present in Japan are ¹³¹I-therapy for Graves’ disease and thyroid cancer, radioimmunotherapy using monoclonal antibodies ( ⁹⁰Y) for malignant lymphoma, and ²²³Ra-therapy for bone metastasis of castration-resistant prostate cancer. Radionuclide therapy using the other kinds of radioisotopes has clearly fallen behind that of overseas countries. The present situation of radionuclide therapy that will be introduced to Japan in future is discussed in this symposium.

Small animal PET systems were developed about a quarter of a century ago. During this time, small animal PET systems have undergone various advances and have been further developed. In this symposium, we have presentations on the development of modern small animal PET systems and their utilization in order to imagine future prospect of small animal PET studies.

Though the disease type of the cardiac amyloidosis is diversified, the transthyretin type (ATTR) amyloidosis has been noticed as a disease for which the health insurance treatment became possible recently. In particular, Tc-99m pyrophosphate scintigraphy is important in the differential diagnosis, and the heart-to-contralateral uptake ratio (H/CL ratio) is also frequently used. Four experts will be invited to discuss nuclear medicine diagnosis, multi-modality diagnosis and treatment of cardiac amyloidosis at this JSNM-JSNC symposium.

AI has been widely applied in medical fields, and nowadays, AI can be utilized to generate images in medicine. In nuclear medicine, especially in PET image, the voxel value has a unit of [Bq/mL], and the generated image by AI have to maintain the absolute value. In this symposium, we will discuss about quantification of PET image with AI.
