Advances in Medical Imaging- Fe8

Magnetic resonance imaging, one of the most important medical imaging advances in disease detection, relies on the injection of contrast material to show specific tissue or to differentiate between healthy and diseased tissue. The materials used in this medical imaging procedure are inclined to have the drawback of being either simply constructed and managed within the body but providing low contrast OR very complex in construction and offering sharper medical imaging contrast but with not as much stability.

The National Institute of Standards and Technology has been working together with researchers at Florida State University and the University of Colorado at Boulder to create new medical imaging contrast materials that are extremely magnetic, unvarying (and thereby easier to manage) and tiny. This blend of qualities will work together to create a harmless, predictable, extremely effective contract solution to be used in medical imaging.

Florida State University researcher Naresh Dalal and other researchers have created a magnetic molecule that they refer to as ?Fe8.? Fe8 contains every one of the preferred traits. This molecule magnet has eight ion bonds, is water-soluble and non-toxic.

Newly published articles describe the molecules test results which show that Fe8 provides good contrast in non-clinical MRI studies over a specific range of concentrations, dismissing an earlier confusion about the value of Fe8 in medical imaging. The earlier research had resulted in conflicting results since the concentration of Fe8 hadn't been taken into account in the course of testing.

These developments are partly due to advances in the field of nanotechnology. Nanotechnologists work with elements that are one billionth of a meter thick. The techniques that measure and manipulate such tiny particles of matter will support further research on materials such as Fe8. Researchers are hoping that these newer medical imaging contrast media will be able to be manipulated for even bigger benefit than this first research implies. For instance, researchers have been looking for methods to ?turn on? and ?turn off? the medical imaging contrast traits by creating contrast media that attaches only to certain molecules or does so only when exposed to certain conditions that can be monitored and managed.

Even though this breakthrough in contrast media for medical imaging is tremendously promising and may well supply a large leap forward in the quality of magnetic resonance imaging, there is still a immense amount of testing and research to take place before Fe8 can be made accessable for use in medical imaging.

Mobility Scooter Independence by Robert Bell
Our bodies deteriorate as we age. For some people this deterioration may mean that they lose the ability to walk as effectively as they once could. Younger people may suffer from an accident that temporarily limits their movement ability. Both groups will benefit from the purchase of a mobility scooter or powered wheel chair to restore the independence of a person suffering from limited mobility. Not being able to do tasks that a person would normally do can be damaging to a perso...

Naturodelic - Herbal Energy Supplements by Keith Andersonn
You surely do not want to miss out all the crazy fun that goes around in a party. You want to be in your best mood and energy to go wild and rock the party wild. But, what if you lack the enthusiasm to dance and sway and be one with the frenzy ambiance that beckons you, but you do not have the capacity to tap your feet, left alone a rocking dance? Party is meant merely for fun, but there is no use if you cannot savor the enjoyment that you are desperately seeking in the jazzed up beats...

Do you have a personality disorder? by Jennifer Baxt
There is still much to learn about personality disorders. Defining the condition can be a little difficult because of how it differs from one person to the next. Those affected with personality disorder will be affected in the way they think, how they feel and how they behave, because personality has much to do with these three areas. Most people will sort out their personalities, such as how they think, feel and behave, by the time they are young adults, but people with personality disorder hav...

Is Gastric Bypass Surgery The Right Solution For Obese Children? by Donald Saunders
While the number of gastric bypass surgeries being performed each year is going up as obesity rates continue to rise in most western countries, a lot of people still believe that surgery is not the right solution for obesity in teens. Nonetheless, this could be changing and, although numbers are still relatively small, teenage gastric bypass surgeries increased by 300% between 2000 and 2003. There are presently two considerations for most surgeons when it comes to surgery as an answer to...

Jenny Craig for Dieting by Li Ming Wong
When it comes to dieting and diet commercials I'm sure that many of you have seen the formerly "Fat Actress" Kirstie Allie singing the praises of Jenny Craig for helping her lose 75 pounds. While most of us would agree that this is quite an accomplishment there are many of us watching from home and thinking there is no way that little tiny pizza is going to make a meal. Much like Weight Watchers, Jenny Craig has experienced phenomenal success over the years and incredible longevity. Als...
