Which type of imaging is NOT a common application of sonography?

The correct answer is indeed the type of imaging that is not commonly associated with sonography, which is CT imaging. Sonography, or ultrasound imaging, utilizes high-frequency sound waves to produce images of structures within the body. It is widely used in various clinical fields, including gynecologic imaging for assessing reproductive health, abdominal imaging for examining organs such as the liver and kidneys, and musculoskeletal assessments for evaluating soft tissues, muscles, and joints.

CT imaging, on the other hand, refers to computed tomography, which employs X-ray technology and computer processing to generate cross-sectional images of the body. While both modalities provide valuable diagnostic information, they are distinct imaging techniques with different applications, and CT is not performed using ultrasound technology. Consequently, CT imaging is not a common application of sonography.
