MRIs Allow for Communication with Vegetative Patients

Scott Routley, 39, was in a car accident that left him in a vegetative state more than 12 years ago. Today, Scott still shows us that he has a “conscious, thinking mind.”

Functional Magnetic Resonance Imaging (fMRI) scans show that he is answering the doctor’s questions. He says he is not in any pain. Adrian Owen, the British Neurologists, says, “We believe he knows who and where he is.”

The team of doctors, led by Owen, is located at the University of Western Ontario at the Brain and Mind Institute. Their original, traditional tests say that Routley was left in a vegetative […]

Is an MRI More Accurate Than a Mammography?

While detecting residual breast cancer, magnetic resonance imaging (MRI) is said to be superior to mammography. Studies show good overall accuracy with an MRI test.
The team compiled 44 studies, working with 2050 patients with 2068 cases of ductal carcinoma, stages II and III.

In summary, the MRI accuracy was 0.88, which is fantastic. While some may argue that the use of contrast in the photographs may cause a likelihood of false-positives, mammography was, in fact, less accurate. Furthermore, the accuracy of an MRI and an ultrasound examination were comparable.

Marinovich with the Journal of the National Cancer Institute states, “the comparative accuracy […]

MRIs Can Catch Prenatal Brain Abnormalities – Restoring Hope

Cerebral Ischemia, which is when the brain receives low blood flow, caused brain cells to die which affects brain function – or so we thought. The use of MRIs has shown that ischemia actually alters the maturation of the neurons; they don’t necessarily die. By catching this irregular blood flow early, measures can be taken to revive the damaged neurons. These measures can be as simply as improving nutrition. Doing this not only improves cortical development but also lowers the chance of a premature birth.

The study involved fetal lambs experiencing cerebral ischemia. An MRI exam was given 1, 2, and […]
