Clinical application of 18F-FDG PET/CT for cardiac neoplasm diagnosis / 中华核医学与分子影像杂志

ABSTRACT

Objective To explore the clinical value of 18F-FDG PET/CT in the diagnosis of cardiac neoplasm.Methods Between January 2007 and December 2011,18F-FDG PET/CT was performed in 8649 patients in our hospital,and 14 (0.16％ ; 11 males,3 females,average age 46.9 (35-68) years) patients were diagnosed with cardiac neoplasm.18F-FDG PET/CT data of those 14 patients were retrospectively analyzed.Final diagnoses were confirmed by either histopathology (n =5) or follow-up (n =9).Results Accurate tumor localization and diagnoses were made by 18 F-FDG PET/CT in all 14 patients.Among them,13 were malignant (2(14.3％,2/14) primary and 11(78.6％,11/14) metastatic tumors (8 HCC,2 lung cancer,1 esophageal cancer) ; SUVmax 3.2-10.7) and 1 (7.1％,1/14) was benign (myxoma).Conclusion 18F-FDG PET/CT is useful for the detection and staging of primary malignant and metastatic cardiac neoplasms.
