Safer CT scanning for children developed in Sweden

ScienceDaily (Apr. 4, 2011) — A research team at the Queen Silvia Children's Hospital in Sweden has developed a method that allows the lowest possible dose of radiation for children having a CT scan while still obtaining good image quality, reveals a thesis from the Sahlgrenska Academy.

Computed tomography (CT) is an advanced form of X-ray examination which generates images that are extremely detailed and very useful in diagnosing patients. If the dose of radiation is lowered too far, however, the scans become blurred and there is a risk of missing small details.

The author of the thesis, medical physicist Kerstin Ledenius from the Department of Radiophysics at the Sahlgrenska Academy, has studied and tested a new method together with radiologists, nurses and medical physicists at the Queen Silvia Children's Hospital. This method manages to combine the lowest possible dose of radiation with what radiologists consider to be sufficiently high image quality for correct diagnosis. In various studies, the research group also looked at the image quality of CT scans of the brains and stomachs of children in various age groups from birth to 17 years.

Computer manipulation of images from previous scans was used to simulate various reductions in radiation dose. The research group then assessed the results of the simulation and decided whether exposure to radiation should be adjusted for the next patient in the same situation, and if so by how much. This made it possible to find the lowest exposure capable of producing a sufficiently good image for each type of examination performed.

"Adjusting exposure is important, as a small patient does not need the same exposure as a large one," explains Ledenius. "Children also differ anatomically from adults, which affects the image quality needed."

The method is already in use at the Queen Silvia Children's Hospital, and Ledenius hopes that more hospitals will follow suit.

"Our method ensures the best possible CT scanning, combining images of high quality with the least possible exposure to radiation."

This medically ground-breaking news is of great significance to those working in the pediatrics field, as it has been long known about the risks of the high levels of radiation used for CT scans. These high levels of radiation have a greater effect on children because of their smaller body size and also because their cells and organs are still in the developmental stage.

This is a puzzle and a work of art all wrapped up into one, and I really like it. See if you can find all the dolphins. We have to exercise our brains just like we have to exercise our bodies. It's sad to let your brain go to mush, so do puzzles, solve riddles, practice memorizing, etc. Give your brain a workout today!

Mexican Spicy Corn recipe | Party Recipes, Entertaining Recipes | by Tarla Dalal | Tarladalal.com | #1091

Ok, this recipe looks too good to resist. Yesterday my son in law made corn that was so good I just almost died. He used frozen corn, and to the cooking water he added honey and asian chili sauce. It was amazing. The corn simmered in that and then he didn't drain it; left it sitting in that yummy mixture so it could soak in. We just used a slotted spoon to serve. Amazing!

What does 'touche' mean

Answer

touch
ADDENDUM
Although "touch(ed)" is a literal translation of the French verb, in English, touché [tü-'shay] is an interjection, used not only to acknowledge a hit in fencing but also, more commonly in conversation, to acknowledge the success or appropriateness of an argument, an accusation, or a witty point. [spelvin]
For Example: Two men are fencing. One strikes, but the blow is parried. The man who parried the blow finds a loophole in his opponent's defenses. He strikes and taps the other man on the shoulder. The blow is legal and the loser varifies this by saying:
"Touche!"
