Cardiac 123I-MIBG scintigraphy and arrhythmic risk in left ventricular noncompaction

Cardiac 123I-MIBG scintigraphy and arrhythmic risk in left ventricular noncompaction.

Left ventricular noncompaction is an unusual but increasingly recognized cardiomyopathy, the etiology of which is still not definitely established. Clinical presentation includes a wide spectrum of scenarios, including heart failure, thromboembolism and malignant arrhythmias, with half of deaths occurring suddenly. Early detection of LVNC is therefore essential to prevent sudden cardiac death. ...

Cardiac I-MIBG scintigraphy and arrhythmic risk in left ventricular noncompaction

Cardiac 123I-MIBG scintigraphy in patients with drug induced parkinsonism.

Cardiac sympathetic dysfunction was investigated using 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy in 20 patients with drug induced parkinsonism (DIP). The mean heart to mediastinum ratio was significantly greater in patients with DIP than in those with Parkinson's disease (mean (SD): 2.07 (0.39) v 1.28 (0.15), p<0.001). MIBG uptake was not different between the DIP patients and...

123I-ioflupane brain SPECT and 123I-MIBG cardiac planar scintigraphy combined use in uncertain parkinsonian disorders

We evaluated the clinical usefulness of the combined use of I-ioflupane brain single photon emission computed tomography (SPECT) and I-metaiodobenzylguanidine (MIBG) cardiac scintigraphy in discriminating uncertain parkinsonism with vascular lesions in striatal nuclei at magnetic resonance imaging (MRI). Forty-three consecutive patients with uncertain parkinsonism and vascular lesions at MRI in...

123I-MIBG scintigraphy and 18F-FDG PET in neuroblastoma.

UNLABELLED The purpose of this study was to compare the diagnostic utility of (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy and (18)F-FDG PET in neuroblastoma. METHODS A total of 113 paired (123)I-MIBG and (18)F-FDG PET scans in 60 patients with neuroblastoma were retrospectively reviewed. Paired scans were acquired within 14 days of each other. RESULTS For stage 1 and 2 neurobl...
