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 nonsuspicious livers. Because of this good agreement the morphologic aspect of basically functional 99mTc-HIDA examinations is emphasized.
