reverse redistribution pattern is defined as decreased activity in the myocardium in the rest phase of the myocardial perfusion scan in comparison with the stress images. there are many studies concerning the etiology and clinical significant of this phenomenon in nuclear medicine literature. the dominant idea about etiology of reverse redistribution is early wash out of the radiotracer from th...

It is suggested that sublingual nitroglycerine can improve the ability of T1-201 for detection of viable myocardium. Methods and Results: In a randomized, double blind study, 50 patients who had fixed defects on stress-redistribution scan, were randomized into two groups. In group I, patients received 0.4-0.8 mg sublingual nitroglycerine, before T1-201 reinjection. In group II, reinjectio...

Reverse supply chain is a process dealing with the backward flows of used/damaged products or materials. Reverse supply chain includes activities such as collection, inspection, reprocess, disposal and redistribution. A well-organized reverse supply chain can provide important advantages such as economic and environmental ones. In this study, we propose a general framework and formulate a m...

OBJECTIVES We sought to assess the mechanism and significance of different (201)Tl redistribution patterns after successful primary stenting following acute myocardial infarction (AMI). BACKGROUND The mechanism of (201)Tl reverse redistribution and the impact of different redistribution patterns on the recovery of contractility after successful reperfusion therapy for AMI remain unclear. ME...

BACKGROUND The clinical significance and pathophysiological mechanisms of reverse redistribution on stress-redistribution thallium-201 myocardial scintigraphy in patients with chronic coronary artery disease are unclear. Recent studies have shown that thallium-201 reinjection is a useful technique for the detection of myocardial viability in chronic coronary artery disease. In this investigatio...

The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. In 20 consecutive acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening ...

Intergenerational Earnings Mobility and Preferences for Redistribution This paper analyzes the extent to which intergenerational upward and downward mobility in earnings are related to individuals’ preferences for redistribution. A novel survey question from the German Socio-Economic Panel Study – whether the taxes paid by unskilled workers are too high, adequate or too low – are used to elicit...
