Abstract:Background: Intracellular sodium (IC) and FDG accumulate in premalignant tumor sites. Hypothesis: High FDG and IC accumulation may characterize tumor stages. Objective: To develop rapid noninvasive hybrid microPET/MRI method to characterize PC3 tumor in mice. Methods: Sodium MRI by Inversion recovery pulse sequence on 4.23 T MRI and FDG Conchord microPET estimate and map both IC sodium and FDG at differentiated premalignant and malignant sites. These were confirmed by histology and DNA fragment analysis. Result: Apoptosis, necrosis, carcinoma, sarcoma, neoplasia were confirmed by immunostaining and MRI/PET imaging showed distinct Na and FDG distribution patterns suitable tool for chemosensitivity assay. Conclusion: IC sodium indicates apoptosis and FDG pattern indicates higher glycolysis in both pre-malignant and malignant tumors by rapid imaging.
