Cardiovascular Adjustments to Gravitational Stress [PDF]

The effects of gravity on the cardiovascular system must be taken into account whenever a hemodynamic assessment is made. All intravascular pressure have a gravity-dependent hydrostatic component.

Cerebral venous system anatomy [PDF]

, 2006
Cerebral venous system can be divided into a superficial and a deep system. The. superficial system comprises of sagittal sinuses and cortical veins and these drain superficial surfaces of both cerebral hemispheres.

The Diagnostic Value of Contrast‐Enhanced Vessel Wall MRI for Diagnosing Neuropsychiatric Systemic Lupus Erythematosus

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging biomarkers for neuropsychiatric systemic lupus erythematosus (NPSLE) are highly needed, and intracranial contrast‐enhanced vessel wall imaging (CE‐VWI) can potentially detect cerebral vessel wall abnormalities in lupus. Purpose To evaluate the diagnostic value of CE‐VWI in differentiating NPSLE from non‐NPSLE.

“MR Fingerprinting for Imaging Brain Hemodynamics and Oxygenation”

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Over the past decade, several studies have explored the potential of magnetic resonance fingerprinting (MRF) for the quantification of brain hemodynamics, oxygenation, and perfusion. Recent advances in simulation models and reconstruction frameworks have also significantly enhanced the accuracy of vascular parameter estimation.

Optimising Radiation Dose Estimation: UNSCEAR DAP‐to‐ED Conversion in Uterine Artery Embolisation

Journal of Medical Radiation Sciences, EarlyView.
This study uses the conversion factors from the ‘UNSCEAR Global Survey on Medical Exposure: A User Manual’ to estimate radiation dose exposure for patients undergoing uterine artery embolisation. Estimating the effective dose provides interventional radiologists and interventional radiographers a better understanding of the stochastic risks associated ...
