Metabolism substrate with negative myocardial uptake of iodine-123-BMIPP.
UNLABELLED Iodine-123-BMIPP is an iodinated methyl-branched-chain fatty acid. Low uptake of BMIPP relative to thallium or other perfusion tracer indicates metabolically damaged but viable myocardium (for example, ischemic but viable myocardium). In some cases, however, negative myocardial uptake of BMIPP is observed. The main purposes of this study were to assess the frequency of such BMIPP fin...
متن کاملAbnormal I-123 metaiodobenzylguanidine myocardial washout and distribution may reflect myocardial adrenergic derangement in patients with congestive cardiomyopathy.
I-123 metaiodobenzylguanidine (MIBG) is a new radiopharmaceutical with properties that allow the characterization of the sympathetic innervation of several organ systems. In this study, we used MIBG with tomographic imaging to evaluate noninvasively the differences in myocardial sympathetic innervation in 14 healthy volunteers and 16 patients with severe dilated cardiomyopathy (CM). Initial (15...
متن کاملAssessment of global cardiac I-123 MIBG uptake and washout using volumetric quantification of SPECT acquisitions
BACKGROUND Assessment of cardiac innervation using single-photon emission computer tomography (SPECT) is less established than planar imaging, but may be more suitable for quantification. Therefore, a volumetric quantification of I-123 MIBG SPECT acquisitions was performed. Reproducibility, the effects of extra cardiac I-123 MIBG uptake and the relation with conventional planar indices were eva...
متن کاملLocalization of chyle leakage site in postoperative chylothorax by oral administration of I-123 BMIPP.
The authors present a 71-year-old woman who had a right chylothorax after right upper lobectomy for lung cancer. As the chylothorax was considered to be due to thoracic duct injury at the time of operation, lymphoscintigraphy was performed by oral administration of I-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP). After visualization of the stomach and intestine, abnormal accumulation of...
متن کاملAbsent myocardial iodine-123-BMIPP uptake and platelet/monocyte CD36 deficiency.
UNLABELLED Global absence of myocardial 123I-15-(p-iodophenyl)-3-(R,S)-methyl pentadecanoic acid (BMIPP) uptake is occasionally noted, and it reflects myocardial long-chain fatty acid uptake abnormality. CD36, a membrane glycoprotein expressed on platelet, monocyte and endothelial cells, may contribute to myocardial fatty acid transport, and its deficiency has been reported in a small subset of...
