Communication errors in radiology - Pitfalls and how to avoid them.

Communication failures are a common cause of patient harm and malpractice claims against radiologists. In addition to overt communication breakdowns among providers, it is also important to address the quality of communication to optimize patient outcomes. In this review, we describe common communication failures and potential solutions providing a framework for radiologists to improve health care delivery.

Wavelet compression of low-dose chest CT data: effect on lung nodule detection.

Purpose: To assess the effect of using a lossy Joint Photographic Experts Group standard for wavelet image compression, JPEG2000, on pulmonary nodule detection at low-dose computed tomography (CT).

Materials And Methods: One hundred sets of lung CT data ("cases") were compressed to 30:1, 20:1, and 10:1 levels by using a wavelet-based JPEG2000 method, resulting in 400 test cases. Each case consisted of nine 1.
