Postsystolic shortening and thickening of ischemic and postischemic myocardium are well-recognized phenomena, but their significance is controversial. To discover whether postsystolic shortening and thickening might represent an active process and to establish their place as possible predictors of functional recovery during and after recovery from ischemia, we examined correlations in severely ...

fundal gallbladder abnormalities result from broad spectrum of pathologic that most of them have no pathological significance and normally causes no symptoms. conversely, early incidental detection of malignant lesions is important because symptomatic lesions are often incurable. so use proper imaging to differentiate between them is important. although ultrasound has been the choice screen met...

OBJECTIVES We developed an automatic quantitative algorithm for the measurement of regional myocardial wall motion and wall thickening from three-dimensional gated technetium-99m sestamibi myocardial perfusion single-photon emission computed tomographic images. BACKGROUND The algorithm measures the motion of the three-dimensional endocardial surface using a modification of the centerline meth...

The aim of this study was twofold, that is the generation of a reliable model for skin barrier disruption and repair and to evaluate recovery of damaged skin after application of vernix caseosa (VC). VC was selected as its wound healing properties were suggested previously, but never clearly demonstrated. Five different levels of barrier disruption in mice, accomplished by tape-stripping, were ...

UNLABELLED Quantitation of regional myocardial function is valuable in patients with coronary artery disease. This study assessed normal heterogeneity and developed and validated normal limits for quantitative regional motion and thickening by gated myocardial perfusion SPECT. METHODS Patients underwent rest (201)Tl/exercise (99m)Tc-sestamibi gated SPECT. Reference values of motion and thicke...

UNLABELLED Heterogeneous perfusion in left bundle branch block (LBBB) has been demonstrated by (99m)Tc-methoxyisobutylisonitrile (MIBI) SPECT. Locally different contraction is also associated with LBBB. Quantitative analysis of myocardial SPECT is influenced by partial-volume effects depending on systolic wall thickening. Therefore, partial-volume effects may mimic perfusion heterogeneity in LB...
