Contrast Agents for Imaging Tumor Angiogenesis: Is Bigger Better?

Prevalence and Costs of Chronic Disease in a Health Care System Structured for Treatment of Acute Illness
All stakeholders in the health care system—including patients, providers, payers, the public, and the government—should now recognize the growing imperative of caring for people with chronic diseases and should come together to design better structures for lifelong continuity of care, with emphasis on evidence-based practice and disease prevention.

Is Infiltrate a Useful Term in the Interpretation of Chest Radiographs? Physician Survey Results
Although we agree that there are cases in which the chest radiologist must describe an abnormality in general and nonspecific terms, we maintain that a description that does not include the term infiltrate is more likely meaningful for the clinician and thus more beneficial to the patient.
