What type of diagnostic imaging is commonly preferred for soft tissue evaluation during pregnancy?

Ultrasound is the preferred method for soft tissue evaluation during pregnancy due to its safety and effectiveness. It utilizes sound waves to create images of the body's internal structures, providing real-time visualization of soft tissues without exposing the fetus to harmful radiation. This is particularly important during pregnancy, where the health and safety of both the mother and baby are critical concerns.

Ultrasound is effective for assessing fetal development, detecting potential anomalies, and monitoring the pregnancy's progress. It is also non-invasive and can be performed multiple times throughout pregnancy without risk. Other imaging techniques, such as X-rays and CT scans, involve ionizing radiation, which can pose risks to the developing fetus and are therefore avoided during pregnancy. Although MRI is safe and can provide detailed images, ultrasound is more commonly used due to its ease of availability, cost-effectiveness, and the immediate information it can provide in a clinical setting.
