There is now a less invasive alternative to colonoscopy called low dose CT colonography (CTC, also known as virtual colonoscopy) that is equally effective at spotting the growths in the colon that could go on to become cancer.

UCFS’s Dr. Srikantan Nagarajan and his Biomagnetic Imaging Laboratory were recently contacted by MythBusters, the popular Discovery Channel show, to help test the myth that people use only 10 percent of the brain. Tune in this Sunday, December 5, at 9 p.m. E/P to see what they found out!

The risks of CT scan radiation and ways to reduce those risks have been making headlines for more than a year.

Engaging in light exercise may actually protect against the cartilage deterioration that is at the heart of osteoarthritis of the knee.

The NLST has shown a significant benefit in outcomes comparing high risk patients screened with CT to patients screened with chest x-rays.

A recent study at UCSF finds powerful CT scanners used for high-end imaging may also pose radiation risks.
