A prospective study to assess the accuracy of ultrasound in the detection and localization of foreign bodies of the extremities was undertaken. Forty-five patients with clinical suspicion of foreign bodies were included in the study. Among 20 patients with radio-opaque foreign bodies, ultrasonic detection of foreign bodies was achieved in 19 patients. In 25 patients, with no radiographic evidence of foreign body, ultrasonic detection of foreign bodies was made in seven patients and among these foreign bodies were confirmed and removed at surgery in five patients. Accurate pre-operative ultrasonic localization of foreign bodies was carried out in three patients.
开展了一项前瞻性研究，以评估超声在检测和定位四肢异物方面的准确性。45例临床怀疑有异物的患者纳入该研究。在20例有不透射线异物的患者中，19例患者的异物通过超声检测到。在25例无异物影像学证据的患者中，7例患者通过超声检测到异物，其中5例患者的异物在手术中得到确认并取出。3例患者术前通过超声准确地对异物进行了定位。
