BackgroundThe aim of this study is to prospectively determine whether the computed tomography perfusion (CTP) can predict the tumor grade in colorectal cancer (CRC), and investigation of the best position of the tumor region of interest (ROI) could improve the tumor grade differentiation.ResultsThe mean blood flow (mBF) at the tumor edge was signif...

Arterial spin labeling (ASL) is a non-invasive tool measuring cerebral blood flow (CBF) and is useful to assess acute neurological deficit. While acute stroke presents as hypoperfused vascular territory, epileptic activity causes cortical hyperperfusion. Other neurological conditions exhibit hyperperfusion, like migraine or secondary "luxury perfus...

BackgroundQuantitative regional strain analysis by speckle tracking echocardiography (STE) may be particularly useful in the assessment of myocardial ischemia and viability, although reliable measurement of regional strain remains challenging, especially in the circumferential and radial directions. We present an acute canine model that integrates ...

BackgroundIn order to better understand the concept of mechanical dyssynchrony, a promising hallmark of cardiac resynchronization therapy (CRT) response, we investigated its effect on regional myocardial metabolism and myocardial blood flow (MBF) in non-ischemic CRT candidates.ResultsThirty consecutive non-ischemic CRT eligible patients underwent s...

Microvascular obstruction is a common repercussion of percutaneous coronary intervention for distal microembolization, ischemia-reperfusion injury and inflammation, which increases post-myocardial infarction heart failure and mortality. Ultrasound-targeted microbubble cavitation (UTMC) may resolve microvascular obstruction while activating endothel...

Abstract Although increasing evidence supports the monitoring of peripheral perfusion in septic patients, no systematic review has been undertaken to explore the strength of association between poor perfusion assessed in microcirculation of peripheral tissues and mortality. A search of the most important databases was carried out to find articles p...

To compare the clinical characteristics and outcomes of patients with acute heart failure (AHF) according to clinical profiles based on congestion and perfusion determined in the emergency department (ED). Overall, 11 261 unselected AHF patients from 41 Spanish EDs were classified according to perfusion (normoperfusion = warm; hypoperfusion = cold)...

Differentiation between glioblastoma and brain metastasis may be challenging in conventional contrast-enhanced MRI. To investigate if perfusion-weighted MRI is able to differentiate glioblastoma from metastasis and, as a second aim was to see if it was possible in the latter group, to predict the primary site of neoplasm. Hundred and fourteen patie...

Classification of acute heart failure (AHF) patients into four clinical profiles defined by evidence of congestion and perfusion is advocated by the 2016 European Society of Cardiology (ESC)guidelines. Based on the ESC-EORP-HFA Heart Failure Long-Term Registry, we compared differences in baseline characteristics, in-hospital management and outcomes...

Arterial Spin Labeling (ASL) is prone to a number of artifacts, which may affect its diagnostic accuracy. To avoid these pitfalls, possible effects on the ASL measurements should be identified. Perfusion asymmetry in the posterior cerebral artery (PCA) territory may be induced by the fetal-type PCA. Whenever a posterior left-right asymmetry is obse...
