Liver Imaging and Detection of Liver Metastases with ^99mTc-HIDA

16 patients with a history or suspicion of malignant disease were investigated scintigraphically for liver metastases. Each patient was studied with ^99mTc-HIDA and ^99mTc-sulphur- or tin-colloid. In 4 patients liver metastases were suspected and confirmed by ultrasonography and/or computerized tomography. The filling defects were visible with ^99mTc-colloids and ^99mTc-HIDA as well. Likewise both radiopharmaceuticals coincided in their parenchymal activity patterns in the non-suspicious livers. Because of this good agreement the morphologic aspect of basically functional ^99mTc-HIDA examinations is emphasized.

16 Patienten mit der Vorgeschichte oder dem Verdacht einer malignen Erkrankung wurden szintigrafisch auf Lebermetastasen untersucht. Jeder Patient wurde mit ^99mTc-HIDA und ^99mTc-Schwefel- oder Zinn-Kolloid untersucht. Bei 4 Patienten wurde der Verdacht auf Lebermetastasen ausgesprochen, der durch Ultraschall- und/oder CT-Unter-suchungen bestätigt wurde. Die Füllungsdefekte waren sowohl mit den ^99mTc-Kolloiden als auch mit ^99mTc-HIDA erfaßbar. Ebenso korrespondierten die Parenchymaktivitätsmuster beider Radiopharmaka in den nicht suspekten Lebern. Angesichts dieser guten Übereinstimmung wird der morphologische Aspekt von vorrangig funktionellen Untersuchungen mit ^99mTc-HIDA hervorgehoben.
