title: Measurement of 24 hour whole body retention of 99Tcm-diphosphonate by a single thyroid probe.
abstract: In a comparative study with a thyroid probe and a whole body counter (WBC) we found that whole body retention (WBR) (2 h and 24 h) may be correctly obtained using a single probe, provided that measurements are taken carefully. With the detecting geometry presented, the single probe yielded only a slightly higher WBR than the WBC (less than 3 percentage points). We conclude that the method is capable of differentiating between pathological and normal WBR values.
