Objective . To show the advantages of extended field‐of‐view sonography in abdominal applications. Methods . Thirty‐one cases were prospectively analyzed in our study. Extended field‐of‐view images were obtained when the radiologist decided that they would offer potential advantages for the examination. When extended field‐of‐view scanning was used, the radiologist determined prospectively whether it was useful according to several categories. Images were obtained with a 2‐ to 5‐MHz curved array transducer or 4‐ to 9‐ and 5‐ to 12‐MHz linear array transducers. Results . Extended field‐of‐view sonography provided several potential benefits over conventional sonography in the abdominal area. The advantages of extended field‐of‐view sonography were better demonstration of the spatial relationship between lesions and adjacent normal structures in 18 cases (58%), accurate quantification of sizes or volumes of large organs or lesions in 16 (52%), better display of the extended and tubular structures in 6 (19%), usefulness for clinical consultations in 7 (23%), and documentation comparable with that of computed tomography or magnetic resonance imaging in 10 (32%). Conclusions . Extended field‐of‐view sonography provided the anatomic context of the lesion in its surroundings and allowed precise measurement and tracing of the extended and tubular structures. The method has notable advantages and clinical applications.
