Development of a novel small-animal myocardial phantom can evaluate the image quality of dual-isotope simultaneous acquisition (DISA)
Myocardial phantom studies are widely used as a tool to accurately assess the physical phenomenon of dual-isotope simultaneous acquisition (DISA) in the small-animal fields. However, the previous phantom did n...

Feasibility of 125I-RGD uptake as a marker of angiogenesis after myocardial infarction
Angiogenesis is an important process facilitating the healing process after myocardial infarction. 125I-RGD imaging may be a promising candidate to image angiogenesis but may also detect inflammation.

Prognostic factors for refractory pheochromocytoma and paraganglioma after 131I-metaiodobenzylguanidine therapy
Given the rarity of refractory pheochromocytoma and paraganglioma (PPGL), outcomes and prognostic factors after 131I-metaiodobenzylguanidine (131I-mIBG) treatment still remain unclear. Therefore, this study evalu...

Colchicine treatment early after infarction attenuates myocardial inflammatory response demonstrated by 14C-methionine imaging and subsequent ventricular remodeling by quantitative gated SPECT
Colchicine has been used as an anti-inflammatory agent and may be cardioprotective after acute myocardial infarction (AMI). We investigated how colchicine administration after AMI affects the myocardial inflam...

High-dose 131I-mIBG as consolidation therapy in pediatric patients with relapsed neuroblastoma and ganglioneuroblastoma: the Japanese experience
Children with relapsed neuroblastoma have a poor prognosis despite modern multimodality therapy. Novel and more effective therapeutic strategies are required for relapsed neuroblastoma. We retrospectively exam...

Prognostic Value of Early Evaluation of Left Ventricular Dyssynchrony After Myocardial Infarction
Dispersion in the contraction of the normally coordinate ventricular system, referred to as left ventricular (LV) dyssynchrony, is constantly observed at different grades of severity after myocardial infarctio...

Quantification of Myocardial Perfusion Defect Size in Rats: Comparison between Quantitative Perfusion SPECT and Autoradiography
Ultra-high resolution single-photon emission computed tomography (SPECT) system, using multiple pinhole collimators, has been applied to the imaging of small rodents. We aimed to compare the myocardial infarct...
