Extended field-of-view sonography: utility in clinical practice
E. E. Sauerbrei
Imaging Services, Kingston General Hospital, Ontario, Canada.
The purpose of this study was to evaluate the usefulness of real-time
extended field-of view sonography in clinical practice (i.e., the frequency
of use in various body systems, the frequency of use by different
sonographers, and the benefits and drawbacks in comparison to conventional
real-time sonography). The use of extended field-of-view sonography was
monitored for a 6 month period. The pattern of usage among different
sonographers and for different body systems was documented. Extended
field-of-view sonography was utilized in 26.5% of patients. In comparison,
color Doppler sonography was used in 23.2% of patients. Utilization of
extended field-of-view sonography varied significantly among sonographers
and among different body systems. Extended field-of-view sonography allowed
measurement of large structures and revealed the anatomic context of
abnormalities in circumstances under which conventional real-time scans
could not provide this information.
