Diagnostic Accuracy of Stress Myocardial Perfusion Imaging in Diagnosing Stable Ischemic Heart Disease.

Conclusion: Coronary Angiography remains the near gold standard in diagnosing ischemic heart disease but is associated with serious complications like stroke, arrhythmias, acute renal failure, infection, etc. Though Myocardial perfusion imaging cannot replace coronary angiogram, it can be used as a reliable and sensitive non-invasive alternate investigation to diagnose stable ischemic heart disease in high risk individuals who are unwilling for angiogram.

Authors: Yadav SR, Kumar R, Gupta N, Ish P, Chakrabarti S, Kumar A Abstract To the Editor Novel Coronavirus disease (COVID-19) was first notified in December 2019 from Wuhan, China. Now, it has spread rapidly and has been declared a pandemic affecting over 200 countries with widespread morbidity and mortality. It has been postulated that the most vulnerable population are the elderly, people living in crowded areas, children and immune-compromised individuals, such as people living with human immunodeficiency virus (HIV). The correlation of tuberculosis (TB), HIV and malnutrition are well documented and hence, peop...

ConclusionsThe results demonstrate that even subtle changes in vessel morphology can be noninvasively quantified. This is of great interest for AD, but also to other models of neurodegenerative diseases involving macrovascular dysfunction.

AbstractPurpose:  To establish multi-modal imaging for the assessment of kidney pH, perfusion, and clearance rate using magnetic resonance imaging (MRI) and multispectral optoacoustic tomography (MSOT) in healthy mice. Kidney pH and perfusion values were measured on a pixel-by-pixel basis using the MRI acidoCEST an d FAIR-EPI methods. Kidney filtration rate was measured by analyzing the renal clearance rate of IRdye 800 using MSOT. To test the effect of one imaging method on the other, a set of 3 animals were imaged with MSOT followed by MRI, and a second set of 3 animals were imaged with MRI followed by MSOT. In a su...

Computed tomography angiography (CTA) has become a mainstay for the imaging of vascular diseases, because of high accuracy, availability, and rapid turnaround time. High-quality CTA images can now be routinely obtained with high isotropic spatial resolution and temporal resolution. Advances in CTA have focused on improving the image quality, increasing the acquisition speed, eliminating artifacts, and reducing the doses of radiation and iodinated contrast media. Dual-energy computed tomography provides material composition capabilities that can be used for characterizing lesions, optimizing contrast, decreasing artifact, a...

Sara AlMarabeh, Mohammed H. Abdulla and Ken D. O'Halloran* Department of Physiology, School of Medicine, College of Medicine and Health, University College Cork, Cork, Ireland Renal sensory nerves are important in the regulation of body fluid and electrolyte homeostasis, and blood pressure. Activation of renal mechanoreceptor afferents triggers a negative feedback reno-renal reflex that leads to the inhibition of sympathetic nervous outflow. Conversely, activation of renal chemoreceptor afferents elicits reflex sympathoexcitation. Dysregulation of reno-renal reflexes by suppression of the inhibitory refle...
