Bone SPECT is better than FDG PET for detecting breast cancer that has spread (metastasized) to a patient’s bones, according to researchers from Shizuoka Cancer Center Hospital in Japan.
FDG PET is an imaging technique based on the increased metabolism of glucose in tumor cells. SPECT is a type of nuclear medicine scan that detects special radioactive elements administered to the patient by the physician. According to the authors, due to these differences in method, bone SPECT images can reveal the location of bone metastases, whereas PET cannot. In addition, bone SPECT can detect where bone is being regenerated after destruction by tumor cells.
For the study, the researchers analyzed the findings in a total of 900 bones in 15 patients with breast cancer who underwent both SPECT and PET. They found that SPECT had a sensitivity of 85% and an accuracy of 96% for detecting bone metastases, whereas PET had a sensitivity of only 17% and an accuracy of 85%. They also found that PET was limited in its ability to reveal certain types of cancer lesions.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
