Low Dose Radiation

UCSF Radiology Encourages Low- dose CT with Lung Cancer Screening Program

UCSF has launched the Lung Cancer Screening Program, an initiative designed for early cancer detection through low- dose CT.

Complexities in Using Effective Doses to Guide CT Scans

Efforts to record and cumulate individual patient radiation dose are being advocated by a variety of societies. The problem with this concept is that at present, we do not have a method of individualizing patient dose.

Better Tracking Needed for Unsafe, Costly Multiple CT Scan Practices

I was recently interviewed for an article, published in The New York Times, about the tendency for some hospitals and imaging centers to perform multiple CT scans on a single patient in one day. Not only is this extra radiation exposure an extremely unsafe practice, but it is also a very costly one for the Medicare system and other insurance companies.

UCSF Leading Effort to Record, Lower CT Doses

The American College of Radiology (ACR) has launched a CT Dose Index Registry in an effort to broaden patients’ protection from excessive radiation. We’ve taken a proactive stance on the issue.

Radiation Risk from Airport Scanners Extremely Low

A study I recently co-authored on backscatter x-ray scanners – the radiation-emitting scanners being used in airports across the country – found that the machines pose an extremely low risk for travelers.

Catastrophe in Japan: Radiation Risks Explained

The tragedy in Japan resulting from the earthquake and tsunami is difficult to comprehend. It is compounded by the damage to the nuclear power plant, resulting in radiation releases with uncertainty as to how much more radiation will be emitted.

Low Dose CT as a Screening Tool for Colon Cancer

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.

Spearheading Strategies and Protocols to Reduce CT Scan Risks

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

Low Dose CT Scan Better for Detecting Lung Cancer Earlier

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