Compared to antiarrhythmic drugs, implantable cardioverter defibrillator (ICD) leads to a more significant improvement in preventing ventricular arrhythmia in heart failure patients. However, an important question has been raised that how to select appropriate patients for ICD therapy. I-123 metaiodobenzylguanidine (MIBG) planar and SPECT imaging have shown great potentials to predict ventricul...

The prognosis for relapsing or refractory neuroblastoma (NB) remains dismal, with a five-year disease-free survival of < 20%, and no effective salvage treatment has been identified so far. 131I-metaiodobenzylguanidine (131I-MIBG) has come to play an essential role in the imaging and therapy of NB over the past 30 years. The role of 131I-MIBG in the treatment of NB is continually expanding. 131I...

123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy has been established as an important technique to evaluate cardiac sympathetic function and it has been shown to be of clinical value, especially for the assessment of prognosis, in many cardiac diseases. The majority of 123I-mIBG scintigraphy studies have focused on patients with cardiac dysfunction due to hypertension, ischemic heart dise...

UNLABELLED 131I-labeled metaiodobenzylguanidine (MIBG) is an established treatment modality for neuroendocrine tumors. Because of low tumor doses, it has a predominantly palliative character. Our approach was to investigate whether intraarterial application of 131I-MIBG has the potential to enhance tumor uptake. METHODS Seventeen patients with primary or metastasized neuroendocrine tumors rec...

Purpose: The suitability of neuroblastoma patients for therapy using radiolabeled meta-iodobenzylguanidine (MIBG) is determined by scintigraphy after the administration of a tracer dose of radioiodinated MIBG whose uptake is dependent upon the cellular expression of the noradrenaline transporter (NAT). As a possible alternative to gamma camera imaging, we developed a novel molecular assay of NA...

UNLABELLED Radiolabeled octreotide analogs (Oct) and metaiodobenzylguanidine (MIBG) offer 2 different approaches for imaging and targeting metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NET). Despite successful establishment of the revised World Health Organization (WHO) classification, which distinguishes between low- and high-grade malignant GEP-NET, there is a lack of scintigra...

BACKGROUND Catheter-based renal sympathetic denervation (RDN) has been considered a potential treatment for therapy resistant hypertension (RHT). However, in a randomized placebo-controlled trial, RDN did not lead to a substantial blood pressure (BP) reduction. We hypothesized that variation in the reported RDN efficacy might be explained by incomplete nerve disruption as assessed by renal 123I...

Paragangliomas (PGLs) are rare neuroendocrine neoplasms of the autonomic nervous system dispersed from the skull base to the pelvic floor. We reported an extremely rare case with coexisting PGL of the retroperitoneum and urinary bladder. The patient complained of episodes of severe headache and palpitation during micturition, with a 1-year history of uncontrolled hypertension. The (131)I-metaio...

Purpose: The survival for children with relapsed or metastatic neuroblastoma remains poor. More effective regimens with acceptable toxicity are required to improve prognosis. Iodine-131–metaiodobenzylguanidine (131I-MIBG) selectively targets radiation to catecholamine-producing cells, including neuroblastoma cells. A pilot study was performed to examine the feasibility of a novel regimen combin...
