‘Old-Fashioned’ Gonad Capsule a Simple and Effective Method For Blocking Radiation to Testes from MDCT Scan

05.01.2005


Shielding the male gonads using a type of lead capsule previously only used in X-ray imaging also reduces indirect radiation to the testes during MDCT of the abdomen and pelvis, according to a new study by researchers from the University of Technology of Aachen in Germany. Protecting the testes from radiation is important because the testes are sensitive to radiation damage, which could result in cancer, infertility, or sperm mutation.



For the study, the researchers analyzed 66 men who underwent routine MDCT of the abdomen and pelvis, 34 of whom used the gonad capsule and 32 of whom went without. The researchers found that the radiation dose to the testicles of the 34 who used the gonad capsule during MDCT was reduced by 87% compared to the other group. The capsule, which is commercially available and comes in different sizes depending on patient anatomy, is a hinged device that encloses the gonads and is attached by the patient himself.

According to the study authors, lead shielding is currently not an established dose-reduction method for CT examinations like it is for conventional X-ray studies. “CT has become widely employed, and the continuous improvement of image quality has meant a dramatic increase in radiation dose to the patient,” said Christian Hohl, MD, lead author of the study.


“There are several attempts to cope with the increasing dose during MDCT, but most of them are complex and expensive. The aim of this study was to prove that the ‘old-fashioned’ gonad shield is an inexpensive and easy-to-use method to protect the male gonads during MDCT,” said Dr. Hohl. “In the beginning we were greeted with smiles for using this ‘oldie’ in a state-of-the-art MDCT scanner,” he added.

The study appears in the January 2005 issue of the American Journal of Roentgenology.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
