title: Lymphography and abdominal computed tomography in staging Hodgkin's disease.
abstract: Lymphography and abdominal CT were performed in 78 patients staged for Hodgkin's disease. In 82% of all patients, both examinations agreed on the presence or absence of lymph node involvement. In the group of 39 patients undergoing lymphography prior to CT, the agreement was 90%. In the group of 39 patients with lymphography following CT, the agreement was 74%. In 50% of the patients with discrepant findings, lymphography revealed abnormal nodes compared with CT. Lymphography was abnormal in 26% of patients with a normal CT scan as the first examination, and in 9% of patients with a normal CT scan as the second examination. It is concluded that lymphography is more reliable than CT in the examination of the abdomen. CT performed after a normal or an abnormal lymphogram adds little additional information. When CT is preferred as the initial investigation in staging Hodgkin's disease, lymphography only adds significant information if the CT scan is normal or equivocal.
