The roles are reversing with real-time instruments more frequently accepted as the primary diagnostic tool and the contact scanner

In addition, when a questionable mass is identified, it can be more readily characterized as cystic or solid by real-time than by contact scanning since the beam can be more easily manipulated perpendicular to the surface of the mass and swept through the mass from side to side so as to both define its margins and internal echo pattern.

The needle can then be replaced by a catheter to provide temporary drainage of the obstructed urinary tract until definitive therapy is instituted.

All of the true real-time ultrasound scanners are hand-held and freely moveable scanning assemblies. The quasi-real-time scanners usually have larger and heavier scanning assembli

Scanning Techniques and Anatomic Considerations,d static ultrasound imaging. This greater exercise of anatomic knowledge results from two characteristics of ultrasound real-time imaging: the smaller field of view of the instruments and the complete flexibility and mobility in placing the transducer at any site on the abdomen.

In addition, since regions of the liver and spleen are larger than the field of view of a realtime scanner, a cross section of either of these organs often cannot be included on a single image. However, real-time imaging of the liver has several advantages over contact scanning. Sm

Since there can be considerable variation in position of the gallbladder in the right upper quadrant, its visualization is more rapidly and easily obtained with real-time instrumentation. In addition, since a major purpose of the gallbladder examination is for the detection of stones,
