    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.

    An open-label, single-arm, multi-center, phase II clinical trial of single-dose [131I]meta-iodobenzylguanidine therapy for patients with refractory pheochromocytoma and paraganglioma

    In this phase II study, we aimed to investigate the efficacy and safety of single-dose [131I]meta-iodobenzylguanidine (131I-mIBG) therapy in patients with refractory pheochromocytoma and paraganglioma (PPGL).

    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...
