Ultrasonographic detection of foreign bodies in soft tissue. A human cadaver study.

The usefulness of ultrasound in the detection of foreign bodies was examined in a blind study in human cadavers using glass, plastic and wood as foreign bodies. Of 65 foreign bodies placed in 102 cicatrices, 58 were found using a 5 MHz transducer. The sensitivity was 89% and the specificity 93% making ultrasound a useful clinical tool for this purpose.
