title: Real-time ultrasound in abdominal examinations.
abstract: Three types of real-time ultrasonic equipment are discussed: sequenced linear arrays, mechancial sector scanners, and phased array systems. Their limitations, including those involving documentation, are briefly reviewed. Although real-time scanners are satisfactory for small, local examinations, they should be used in conjuction with static B-scanners for larger abdominal surveys.
