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...

One of the significant contributors to the variation of H/ M ratio in cardiac imaging, are the settings of the regions of interest (ROIs) that are used. Currently, as correctly described by Chen et al. [1, 2], there are three main approaches ROI is placed along the anterior part of the LV wall [2]. In our current ongoing study in pediatric patients by van der Palen et al.., we compared both app...

hydatid disease, caused by echinococcus granulosus, is a common infectious disease in endemic areas such as southern europe and the middle east. the incidence of this disease, however, is on the increase in northern europe due to the migration of labor and also tourism. we report a case of the hydatid cyst of the mediastinum, the diagnosis of which was established by the hemagglutinin test and ...

PURPOSE Myocardial sympathetic imaging with 123I-meta-iodobenzylguanidine (123I-mIBG) has gained clinical momentum. Although the need for standardization of 123I-mIBG myocardial uptake has been recognized, the availability of practical clinical standardization approaches is limited. The need for standardization includes the heart-to-mediastinum ratio (HMR) and washout rate with planar imaging, ...

Primary anterior mediastinum undifferentiated high grade pleomorphic sarcoma is rare that most physician including thoracic surgeon would not experience this disease. Huge anterior mediastinum tumor pressed the heart and it invaded into the left pulmonary arterial trunk. We did the mediastinum tumor resection, left pneumonectomy and left phrenic, sympathetic and vagus nerve merger excision. But...
