White children are more likely to receive cranial (head) CT scans in an emergency department following minor head trauma, compared with African-American or Hispanic children, a study published by researchers at UC Davis has found. The study findings do not indicate that CT (computed tomography) scans are underused in African-American and Hispanic children. Rather, the researchers suggested that white children may receive too many CT scans and thus may be exposed to unnecessary radiation....

Researchers in the study focused on a condition known as acute coronary syndrome, which includes...

The report of a study conducted at nine U.S. hospitals appears in the July 26 New England Journal of...

Advances in diagnostic imaging have benefited children with otolaryngologic disease, allowing shorter hospital stays, fewer invasive procedures, more targeted surgical procedures, and earlier and more precise diagnoses.

A new study of 1,400 Medicare-aged patients reinforces CT colonography as a screening tool for colon cancer, adding to the continued debate over Medicare coverage of the procedure. In 2009, the Centers for Medicare and Medicaid Services indicated that CT colonography would not be covered, in part, because outcomes data specific to the Medicare population was not available. "Our study answers several of the questions Medicare asked about this procedure," said Brooks Cash, MD, one of the...
