transient ischemic left ventricular dilation (tid) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. the patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (lad) territory perfusion abnormality have more probability of having tid. evaluati...

tion of hemodynamically significant coronary artery stenosis: incremental diagnostic value of dynamic CT-based myocardial perfusion imaging. of dynamic computed tomography adenosine stress myocardial perfusion imaging in estimating myocardial blood flow at various degrees of coronary artery stenosis using a porcine animal model.

Although single photon emission computed tomography (SPECT) is preferable for myocardial perfusion scintigraphy, in a minimal number of circumstances, planar imagingmay be useful ormay be the onlymodality available. Purpose. To evaluate regional myocardial perfusion and function. Planar imaging is an acceptable method for myocardial perfusion imaging. The anatomy of the heart is sufficiently si...

OBJECTIVE Cerebral perfusion imaging with computed tomography (CT) or magnetic resonance (MR) is widely available. The optimum perfusion values to identify tissue at risk of infarction in acute stroke are unclear. We systematically reviewed CT and MR perfusion imaging in acute ischemic stroke. METHODS We searched for papers on MR or CT perfusion performed <24 hours after stroke that assessed ...

BACKGROUND Stroke management would benefit from a broadly available imaging tool that detects perfusion deficits in patients with acute stroke. OBJECTIVE To determine the role of dynamic, single-slice computed tomographic (CT) perfusion imaging (CTP) in the assessment of acute middle cerebral artery stroke. DESIGN AND PATIENTS Imaging with CTP and CT within the first 6 hours of symptom onse...

BACKGROUND AND PURPOSE Cerebral perfusion imaging in acute stroke assists in determining the subtype and the severity of ischemia. Recent studies in perfusion models and in healthy volunteers have shown that ultrasound perfusion imaging based on microbubble destruction can be used to assess tissue perfusion. We applied ultrasound microbubble destruction imaging (MDI) to identify perfusion defic...

BACKGROUND Even though acupuncture has long been used for alleviating symptoms related to vascular insufficiency, the clinical effect of acupuncture on peripheral circulation has not been fully confirmed. In this study, we investigated whether a near-infrared optical imaging-based method can be used to evaluate the efficacy of the acupuncture procedure to induce changes in peripheral tissue per...

STUDY OBJECTIVES The functional impact of pulmonary vein (PV) stenosis on pulmonary perfusion after radiofrequency ablation (RFA) for atrial fibrillation (AF) has not been systematically evaluated previously. Therefore, we correlated magnetic resonance (MR) pulmonary perfusion imaging with single-photon emission CT (SPECT) perfusion and with the degree of PV stenosis (PVS) apparent on MR angiog...

Objective: Measurement of blood-brain permeability dysfunction in active and chronic MS lesions with T1-weighted dynamic contrast-enhanced MRI to show variation in inflammatory activity Background: blood-brain-barrier perfusion characterization impaired in MS as some studies have shown recently buta comparison between perfusion parameters in contrast-enhanced and non-enhanced lesions not have ...
