The National Lung Screening Trial (NLST), the largest randomized lung screening trial ever conducted, showed a substantial benefit for heavy smokers aged 55-74 who were screened for lung cancer using low-dose computed tomography (LDCT) scans. CT screening identified more lung cancers at earlier stages resulting in a significant decrease (20 percent ) in lung cancer mortality in the screened group.

A recent study examined “Stenting vs. Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis,” and raised questions about the value of stents for the treatment of strokes.
New UCSF research confirms that computed tomographic colonography (CTC) administered without laxatives is as accurate as standard colonoscopy in detecting polyps that are clinically significant and potentially cancerous.
New findings show that MRI is more effective than clinical examination for identifying patients whose tumors will respond well to chemotherapy before breast cancer surgery.
The widespread use of CT has resulted in higher levels of radiation exposure for the general population—including children. However, children who receive these scans do so for an immediate and significant health condition. At UCSF we are advocates for the rational and appropriate use of medical imaging.
Recent evidence supports the belief that coronary CT angiography (coronary CTA) is as good as or better than the current clinical standard practice performed to exclude coronary disease in the emergency room.
