Incidental abnormalities detected in cancer patients by radiologists using positron emission tomography (PET) may signal new, unrelated malignancies, according to a study appearing in the February issue of the journal Radiology.
"The unexpected abnormalities we followed up on were significant," said the studys lead author, Harry Agress Jr., M.D., who is director of nuclear medicine at Hackensack University Medical Centers PET center. "Approximately 71 percent of the lesions that were confirmed with biopsy were either malignant or premalignant. Typically, these cancers were not symptomatic and were unrelated to the primary cancer for which the scan was performed."
The researchers evaluated 1,750 PET scans of known or suspected cancers to determine the importance and malignant potential of additional, unexpected abnormal findings encountered during routine PET evaluation. They identified 58 abnormalities in 53 patients. Most abnormalities were found in the colon, while others were located in the breast, fallopian tube, uterus, gallbladder, larynx, ovary, bone and thyroid.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
