Researchers in North Carolina, Maryland, and Texas studied the effects of playing football for one season had on children aged 8-13. While most are familiar with the concussions pro-football athletes experienced, these researchers wanted to see if other head impacts that do not lead to a concussion have an effect.
The study included 25 children with average age of 11, and they underwent scanning before and after their season of football. While necessary steps were taken with children who did experience a concussion, they were excluded from this study. The results showed differences in white matter in the brain.
Among this test group, there were changes in the white matter and several other connections within the brain. Researchers could not conclude if there was any long-term affects to these changes, but it was noted there was a decrease in activity in some areas of the brain, at least after the season of football.
At Accessories for MRI, we aim to offer the best for pediatric needs. For children in this sort of study, we offer several MRI accessories to provide patient comfort and safety. While kids may feel invincible playing a game of football, they may not feel quite so thrilled at the prospect of a MRI scan. If you would like to make your MRI more inviting to children, we offer a wide range of pediatric medical equipment, and MRI Accessories, like SAMM M.D. and MRI Stereo.

MRI Scanning offers a new way of looking at the human body. When MRIs were first available, we were able to detect illness before it spread. MRIs were used only when one was sick and needed medical treatment. However, MRI machines can offer much more than telling someone if they are sick or not.
Today, we can use MRI Scanning for research, and discover new information. With new information from these studies, we can better understand the human body, and perhaps improve life outside of the the hospital. One such study took place at the Medical Center of the University of Freiburg in Germany. Researcher used MRI machines to better understand speech.
Scientists used ma
gnetic resonance imaging to find out if articulation is dependent on loudness. They discovered that for the vowel /a/, loudness does have an effect on articulation during singing. In other words, they are using scientific methodology to help singers improve their performances.
At Accessories for MRI, we advocate research and the many ways MRI machines can be used to improve the quality of life. We offer a wide inventory in MRI Transport, MRI Pediatrics, and MRI Patient Comfort to improve MRI machines in either your medical or research work. One of our goals is to improve the quality of the MRI Suite, so take a look at our inventory to see what we can offer you.

Come September, something exciting is hitting the medical market.
Medtronic has announced that their Evera SureScan heart defibrillator implant can be safely used in an MRI scanner. It is stated that it is designated “MR conditional,” which essentially means having an MRI with one is not known to pose any hazardous conditions to patients.
This device is implanted in a patient’s chest to treat dangerous rapid heartbeats. It is intended for patients at risk of sudden cardiac arrest. Medtronic has stated that patients who have an Evera SureScan device implanted in their bodies can receive MRI scans on any part of their body without positioning restrictions. The MR Conditional designation only applies when Evera is used with a specific wire Medtronic has just recently developed.
Not only is this big news for doctors, radiologists, and technicians, but this could revolutionize a patient with heart problem’s comfort when receiving an MRI. The powerful magnets in MRI machines interfere with standard heart implants by making them speed up or making certain components turn or overheat, so safety regulators have always recommended that patients avoid MRI scans. Medtronic claims that is a problem because about one third of ICD patients will need an MRI within four years of having the device implanted. The company said it was changed some software and hardware inside the titanium Evera implant to reduce all risks.
MRI-safe pacemakers have been developed and sold for years. This is perhaps because they are more common in patients. However, ICD’s are a little less common, and a whole lot more complicated. Pacemakers are used to treat slow heartbeats and they deliver a steady stream of electrical pulses to keep patient’s hearts beating normally. ICDs are usually more complex; they contain pacemakers and additional systems that are used to sense irregular heartbeats and deliver electrical pulses or shocks to return the heart to a normal rhythm. Doctors everywhere are agreeing that medical device companies are focusing on making their devices MRI-safe because the scans are becoming so common.
Medtronic PLC said that a clinical trial in May showed MRI scans did not affect Evera’s ability to detect dangerous heart rhythms and responses from them.
This product will be available in September.

Hospitals are now implementing new technologies to put patients at ease in the MRI Suite. One such hospital is the Pardee Hospital in North Carolina, which dubbed theirs the MRI Caring Suite.
The Pardee Hospital aims to reduce anxiety with their MRI Caring Suite. It offers a wider bore opening to accommodate up to 500 pounds; this allows patients who suffer from claustrophobia to feel more at ease. The hospital has also installed video, music, and soothing ambient lighting to ease the MRI scanning process.
MRI Suites are not always known for their comfort or ease. MRI Suites are usually, small enclosed spaces, which cause can anxieties in patients. They can be dark and loud as well. For many, MRI scanning is not an enjoyable process. However, with innovations in MRI comfort care, like at Pardee Hospital, there are opportunities for new technologies.
At Accessories for MRI, there are several products that enhance MRI comfort. Accessories for MRI's goal is to improve MRI comfort and to offer it at an affordable cost. Healthcare and comfort ought to be synonymous with another, not exclusive.
One such product to enhance patient comfort is the SAMM System. The SAMM System, or the Safety and Movement Monitoring System allows MRI technicians to watch for patient movement or discomfort in the MRI Suite. This helps patients know they are safe in the MRI Suite. No longer does MRI scanning need to be an isolating process. SAMM System allows patients and technicians experience a safer environment. With a safe environment, comes patient comfort and ease.

The movie, “Alice in Wonderland” is now being used to distinguish patients with first-episode psychosis from control subjects. These findings will be presented at the 28th European College of Neuropsychopharmacology Conference in Amsterdam.
“In this work, we attempted to determine whether a person is a first-episode psychosis patient or a healthy control subject just by looking at their brain activity recorded during movie viewing,” said lead researcher Eva Rikandi of Aalto University, Helsinki, Finland.
“We found, that by monitoring activity in a region known as the precuneus we were able to distinguish patients from control subjects especially well. This would mean that the precuneus, a central hub for the integration of self- and episodic-memory-related information, plays an important role in this kind of information processing of psychotic patients.”
High-precision fMRI is often used in neuroscience to locate brain activity in response to stimuli. These new experiments often look at severely ill patients, such as those with repeated episodes of psychosis, making the differences in the brain activity easy to detect when compared to the general population. Unfortunately, early psychosis is more difficult to detect. The patterns in the brain are not as “natural” so the differences are subtler when compared to the control groups.
Researchers also face the challenge of making sure that all the patients are concentrating on the same things while being scanned. This is where they came up with the most inventive solution: The patients were scanned while watching “Alice in Wonderland”, which guaranteed that they were receiving the same information, and concentrating on the same thing.
Using a 3-Tesla MRI device, the scientists scanned the brains of 46 first-episode psychotic patients (which means that they’ve only endured one psychotic event) and then they scanned 32 healthy control subjects, while watching the movie.
The findings were clear: they showed significant differences within the precuneus region of the brain, a region connected with memory, visual perception awareness, self-awareness, and aspects of consciousness.
“We were able to achieve almost 80 percent classification accuracy using these methods. This is the first study which directly associates the beginnings of psychosis with the precuneus, so it is now important that much more research is done in this area,” said Rikandi.
These researchers hope that this approach will lead to earlier screening and better diagnosis of at-risk populations.
“The interesting question here is how patients with psychosis, even in their first episode, process information in a different way,” said ENCP President-Elect, Professor Celso Arango.
“Specifically how a movie such as `Alice in Wonderland’ elicits the participation of different brain areas, and how that relates to the history of the person watching.”
“What we would like to know is if patients with psychosis might see this as more or less relevant to their
