Final answer:
Ultrasound is a simple and safe means to diagnose cecal dilation, avoiding the use of electromagnetic radiation and providing clear images for various abdominal conditions.
Step-by-step explanation:
A simple means of diagnosing cecal dilation is by using ultrasound imaging. Unlike X-rays or CT scans, ultrasounds do not use electromagnetic radiation and are therefore a safer option, particularly during pregnancy. For example, ultrasound technology is widely used to monitor pregnancies for this reason. Moreover, other imaging techniques like endoscopic ultrasounds can reveal issues within the abdomen without the need for more invasive procedures, and they may provide a clear image to diagnose conditions such as severe pancreatitis or gallstones.
