Introduction: Myocardial perfusion imaging using gated SPECT and phase analysis is an effective tool in evaluation of mechanical dyssynchrony. The purpose of this study was to determine the normal ranges of global and regional phase parameters. Methods: A total of 100 patients with normal resting and stress electrocardiograms, low pretest likelihood for c...

Echocardiography is themostwidelyusednon-invasivecardiac imaging for assessing the cardiac structure and function. Echocardiography has the advantage of low cost, no radiation risk, and great availability. However, as for any diagnostic test, its interpretation depends on its ability to accurately detect abnormalities. Actually, the definition of ‘abnormal’ relies on the definition of ‘normal’ ...

INTRODUCTION The immature platelet and immature reticulocyte fractions represent the ratios of platelets and reticulocytes recently released into the circulation and thus with higher RNA content. They are considered early indicators of bone marrow recovery. OBJECTIVE The aim of this study was to determine the reference ranges for the immature platelet and reticulocyte fractions of hematologic...

Thyroxine (T4) screening values in infants of low birthweight in relation to birthweight and gestational age are reported. There were 86 healthy infants of low birthweight (group 1), and 29 preterm infants with respiratory distress syndrome (group 2). All the group 2 infants and 36% of those in group 1 had a T4 screening value below the cut-off point (-2.1 SD). In group 1 there was a significan...
