Newly Designed Na**rods Act as Dual Imaging Agents for Improved Diag**stics and Surgical Use
https://www.medgadget.com/wp-content/uploads/2017/06/dual-mode-imaging-300x225.jpghttps://www.medgadget.com/wp-content/uploads/2017/06/dual-imaging.jpgScientists at the PNG College of Tech**logy have developed new na**scale rods that may be an effective dual-mode imaging agent for detecting cancer. The na**rods can be seen using both magnetic resonance and optical imaging techniques. Combining the two offers potentially better localization results during pre-op imaging, but can also allow for easy to use optical intraoperative identification of tumor tissue that was originally spotted using MRI.
The na**rods are made of gadolinium oxide doped with the element europium. They are also coated in a layer of silica so that the potentially toxic material they’re made of doesn’t make direct contact with the body. The performed in vitro cytotoxicity study that showed low levels of toxicity at reasonable concentration levels.
These are still early developments for this tech**logy and the na**rods may be more finely tuned to create a more powerful signal. This would further reduce the required concentration levels, potentially one day leading their introduction into clinical practice.
According to Dr. R. Arun Kumar, Associate Professor, PSG College of Tech**logy, “The developed na**-contrast serves for both MRI and optical imaging. Therefore, the imaging of cancer with higher sensitivity and spatial resolution is possible. The mortality rate can also be reduced.”
