“We know, from statistics, that there are cancers diagnosed through screening that wouldn’t otherwise have been diagnosed—because the woman dies of something else first, because she might get run over by a bus, or she might have a heart attack, or she might live to 90 and it would just sit there, and she wouldn’t have died of breast cancer. You don’t know who that woman is. You just know that statistically, she exists.”
— Julietta Patnick, the director of cancer screening programs for the British National Health Service, as reported in The New York Times |

Editor’s E-Note
Deborah Levine, MD, wrote a brief editorial in last month’s RSNA News pointing out that the best radiation dose reduction is complete dose reduction, using ultrasound when possible to complete the imaging task. It made good sense; Levine wrote about clinical, financial, and practice-building reasons why radiology groups should, in her words, “pick up the probe.”
You can read Levine’s editorial at RSNA.org. In the meantime, here are some ultrasound-related news items from the recent meeting of our friends at the American Roentgen Ray Society.

Ultrasound News From ARRS
Ultrasound Can Reduce Thyroid Biopsies for Low-Risk Patients
The prevalence of benign thyroid nodules is high and certain ultrasound features, suggesting malignancy, can help radiologists determine whether a biopsy is needed, according to a study performed at the University of California San Francisco Medical Center.
“Our study supports previous data showing that some sonographic features of thyroid nodules are suggestive of malignant nature and should lead to biopsy,” said Dorra Sellami, MD, the study’s lead author. “These features include microcalcifications (which increase the risk of cancer 16-fold), a shape taller than wide (increases the risk of cancer 3.7-fold), and hypoechogenicity (a twofold increase in the risk of cancer). Other features may suggest that a nodule is benign, such as hyperechogenicity (a 40% increase in the risk of cancer).”
