title: [Radioimmunodetection in the diagnosis of trophoblastic disease].
abstract: OBJECTIVE
  To study the efficiency of radioimmunodetection (RID) to locate the loci of trophoblastic disease.
  
  
  METHODS
  24 RIDs were performed with 131I labeled mouse anti-hCG monoclonal antibodies on 21 patients with trophoblastic disease.
  
  
  RESULTS
  Of 24 RIDs performed, 13 were positive, including one false positive; 11 were negative, including two false negative. The sensitivity of RID was 85.7%, the specificity was 90.0%, the accuracy was 87.5%. In 8 patients who underwent operations after RID, the findings of RID were in accordance with the pathologic and immunohistologic findings.
  
  
  CONCLUSIONS
  RID is an efficient imaging method for trophoblastic disease. In some cases, RID showed its value as a functional diagnostic method.
