CT Scans May Increase Risk Of Cancer

CT Scans May Increase Risk Of Cancer

Many don’t hesitate to think twice when they go for any recommended medical testing, but facts are that some diagnostic and follow-up imaging scans can be detrimental to health, especially if radiation is involved. Computerized tomography scans are one such diagnostic imaging protocol as it blasts ionizing radiation into the body that can significantly increase …

Developing A New MRI

IMÁGENES DE RESONANCIA MAGNÉTICA  DE ALTA RESOLUCIÓN EN ESCALA NANOMÉTRICA

Chinese scientists are building a new powerful MRI to look deep into the human brain to learn more about its complex structure; suggesting the project will revolutionize brain studies and assist in creating future treatments for Alzheimer’s and Parkinson’s disease. The budget is greater than that of the world’s largest telescope at $126 million, which …

When Should Imaging Be Ordered For Seizures?

ESTUDIO: LOS MISMOS GENES IMPULSAN MUCHOS PROBLEMAS PSIQUIÁTRICOS

More conservative use of emergency department neuroimaging for non-index seizures is supported by new findings from researchers at Epilepsia. Emergency department visits for patients with seizures often have them undergoing neuroimaging, typically CT scans. Imaging in adult patients presenting with onset index seizures leads to a change in care for 9 to 17% of patients, …

MRI May Predict Alzheimer’s Risk

logo

Using MRI, researchers may be able to predict which adults with mild cognitive impairment are more likely to progress to Alzheimer’s disease. Using magnetic resonance imaging (MRI), researchers may be able to predict which adults with mild cognitive impairment (MCI) are more likely to progress to Alzheimer’s disease.  Individuals with MCI develop Alzheimer’s  Disease at …

Research Diagnostics Can Reveal Significant Medical Findings

logo

In an estimated 40% of research subjects who undergo medical imaging, a significant medical finding unrelated to the study, but meaningful to the person’s health may be revealed. Often, research subjects enrolled in clinical studies are given medical imaging diagnostics, to establish baseline health and monitor progress through the trial. Nicholas M. Orme, from Mayo …
