Influence of postural changes on haemodynamics in internal carotid artery bifurcation aneurysm using numerical methods.

Cerebral intracranial aneurysms are serious problems that can lead to stroke, coma, and even death. The effect of blood flow on cerebral aneurysms and their relationship with rupture are unknown. In addition, postural changes and their relevance to haemodynamics of blood flow are difficult to measure in vivo using clinical imaging alone.

Venous reflux into renal and spinal veins on MDCT in a surviving patient.

In patients of cardiac arrest or near death, opacification of inferior vena cava and renal veins during the arterial phase of intravenous contrast administration at computed tomography (CT) examination is well known. We present a case of extensive reflux into renal and spinal veins in a patient who survived for 1 week following multidetector computed tomography (MDCT) examination without any life supporting devices.

Quantitative Predictive Imaging Biomarkers of Lumbar Intervertebral Disc Degeneration.

Study Design: Observational comparative study.

Purpose: To compare fractional anisotropy (FA) maps with T2 values of the nucleus pulposus (NP) and annulus fibrosus (AF) of intervertebral discs in healthy volunteers and patients to develop a predictive disc health scale.

Overview Of Literature: T2-weighted magnetic resonance imaging (MRI) is not sensitive to early morphological changes and provides no quantitative biomarker profile for early degeneration.
