Cardiac Micro–Computed Tomography Imaging of the Aging Coronary Vasculature

Cardiac micro-computed tomography imaging of the aging coronary vasculature.

BACKGROUND Alterations at the level of the coronary circulation with aging may play an important role in the evolution of age-associated changes in left ventricular (LV) fibrosis and function. However these age-associated changes in the coronary vasculature remain poorly defined primarily due to the lack of high resolution imaging technologies. The current study was designed to utilize cardiac ...

Three-dimensional microcomputed tomography of renal vasculature in rats.

Current microscopic methods to view renal microvasculature reveal only a very limited portion of the total renal volume. Identification of connectivity for postglomerular vessels in the cortex and the medulla during functional states related to changes in sodium excretion will help better to understand the coupling of renal vasculature to tubular function. The purpose of this study was to inves...

Cardiac imaging: Part 2, normal, variant, and anomalous configurations of the coronary vasculature.

OBJECTIVE Noninvasive imaging of the heart and coronary vasculature using CT and MRI is a new and exciting opportunity for radiologists. The purpose of this pictorial essay is to review normal and variant anatomy of the coronary arteries and of several coronary anomalies that may be clinically significant. The coronary veins and artifacts simulating disease will also be briefly covered. This ar...

Cardiac magnetic resonance imaging and coronary computed tomography angiography in the diagnosis of anomalous coronary artery.

Retrograde perfusion and filling of mouse coronary vasculature as preparation for micro computed tomography imaging.

Visualization of the vasculature is becoming increasingly important for understanding many different disease states. While several techniques exist for imaging vasculature, few are able to visualize the vascular network as a whole while extending to a resolution that includes the smaller vessels. Additionally, many vascular casting techniques destroy the surrounding tissue, preventing further a...
