[Double-indicator radionuclide study of liver metastases]
Abstract:
75Se-methionine as a diagnostic agent was shown to possess a varied activity as regards metastatic liver tumors which manifested themselves in a great variability: from enhanced to the absence of its incorporation in the "cold zones" detected with the help of colloid 113mIn. An analysis of the data on 63 patients with cancers of different sites with liver metastases showed that the diagnostic value of 75Se-methionine combined with colloid 113mIn reached 90%. It was concluded that 75Se-methionine could serve as a valuable diagnostic test in the detection of malignant liver tumors.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
