A decreased cardiac (123)I-metaiodobenzylguanidine ((123)I-MIBG) uptake has been used as a powerful tool to identify Lewy body disease, such as idiopathic parkinson's disease (IPD). We performed cardiac (123)I-MIBG scintigraphy in patient with autosomal recessive juvenile parkinsonism (ARJP) with parkin gene mutation (PARK2). The findings showed normal cardiac (123)I-MIBG uptake. Therefore, alt...

(131)I-metaiodobenzylguanidine (MIBG) has been used as a therapeutic agent for pheochromocytoma. Tumor localization and precise staging are essential for therapy with high-dose (131)I-MIBG. The sites and extent of (123)I-MIBG uptake are usually estimated to predict the effectiveness of therapy before administration. However, conventional scintigraphic images provide insufficient anatomic inform...

Pixon noise reduction was applied to 18 planar images, six each from 99mTc-methylene diphosphonate (99mTc-MDP), 67Ga citrate (67Ga), and (123)I-metaiodobenzylguanidine ((123)I-MIBG) studies. Pixon processing increased patient signal-to-noise ratio, 6.8-11.8 fold. Three specialists preferred processed images 44 of 54 times with good agreement (87%). Most (9/10, p<0.02) of the null and negative p...

A 10-year-old boy presented with a 3-day history of worsening abdominal pain, fever, emesis and melena. Abdominal ultrasound revealed a right upper quadrant mass that was confirmed by computed tomography angiogram (CTA), which showed an 8 cm well-defined retroperitoneal vascular mass. (123)Iodine metaiodobenzylguanidine ((123)MIBG) scan indicated uptake only in the abdominal mass. Subsequent bi...

Patients with long dialysis vintage have low cardiac output for various reasons. Although kidney transplantation is known to improve cardiac mortality, patients are sometimes evaluated as contraindicated for transplantation because of cardiac risk. We successfully performed kidney transplantation for a patient with a long dialysis vintage and dilated cardiomyopathy. Sequential (123)I-metaiodobe...

(I-MIBG) Imaging in Brugada Syndrome To the Editor: We read with interest a recent article in Circulation by Wichter et al1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but in non...

The autonomic nervous system interacts in the pathophysiology of heart failure. Dysfunction of the sympathetic nervous system has been identified as an important prognostic marker in patients with chronic heart failure. At present, cardiac sympathetic nerve imaging with 123-iodine metaiodobenzylguanidine [123-I MIBG] has been employed most frequently for the assessment of cardiac sympathetic in...
