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.

Utility of serum pancreatic enzyme levels in diagnosing blunt trauma to the pancreas: a prospective study with systematic review.

Introduction: Reliability of serum pancreatic enzyme levels in predicting pancreatic injuries has been a parameter of interest and the present recommendations on its utility are based primarily on anecdotal observations. The aim of this study was to evaluate the utility of serum pancreatic enzyme assessment in predicting blunt pancreatic injury with imaging and surgical correlation and compare our results with a systematic review of literature till date.

Methods: A prospective cohort study conducted over 4 years in a tertiary care referral centre with 164 consecutive patients who presented to the emergency department with a history of blunt abdominal trauma and had serum pancreatic enzyme assessment, USG and subsequent diagnostic CECT were analyzed.

Quantitative and qualitative bowel analysis using mannitol, water and iodine-based endoluminal contrast agent on 64-row detector CT.

Objective: To assess the performance of mannitol as a luminal contrast as compared to water and positive contrast in evaluation of bowel on multidetector computed tomography (MDCT).

Materials And Methods: Three hundred patients were randomly selected for this study and were divided equally into three groups. Each subject received 1500 ml of oral contrast.
