1. Recognize the most common artifacts encountered in CT imaging of obese and morbidly obese patients. 2. Understand various methods of optimization of CT protocols for obese patients that can improve diagnostic imaging quality. 3. Become familiar with situations where obesity-related artifacts may not render images non-diagnostic and may be acceptable
