Contrast-enhanced MR angiography [PDF]

Abdominal Imaging, 1998
Gadolinium-enhanced MRA in the abdomen provides a safe, fast, and cost-efficient alternative to conventional diagnostic angiography. Numerous recent advances allow for high-resolution breath-hold imaging with optimal arterial-phase gadolinium bolus timing. As the technique is refined further, greater spatial and temporal resolution will become possible,

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Screened Poisson Equation for Image Contrast Enhancement

Image Processing On Line, 2014
In this work we propose a discussion and detailed implementation of a very simple gradient domain method that tries to eliminate the effect of nonuniform illumination and at the same time preserves the images details. This model, which to the best of our
