Key result
F-18 FDG PET imaging correctly identified a right atrial mass as a malignant tumor in a patient where echocardiography and MRI could not differentiate between tumor and thrombus.
Why the study?
Can F-18 FDG PET imaging differentiate between a tumor and a thrombus in a patient with a right atrial mass?

Can F-18 FDG PET imaging differentiate between a tumor and a thrombus in a patient with a right atrial mass?
F-18 FDG PET imaging can be a useful tool in differentiating malignant cardiac tumors from thrombi when echocardiography and MRI are inconclusive.
May aid differentiation of right atrial masses when echo/MRI inconclusive; leaves open need for prospective validation.
Fluorodeoxyglucose (FDG) positron emission tomography (PET) has been shown to be useful in the diagnosis and staging of various malignancies. The main advantage of PET is its high sensitivity in identifying malignancies at an early stage. The authors present a patient in whom transthoracic echography and MRI revealed a right atrial mass. The diagnosis was difficult between tumor and thrombus, but PET imaging correctly suggested a malignant tumor.

Biancheri et al. (2007) conducted a case report in Right atrium metastasis from a vesical carcinoma (n=1). F-18 FDG PET vs. Transthoracic echography and MRI was evaluated on Identification of malignancy. F-18 FDG PET imaging correctly identified a right atrial mass as a malignant tumor in a patient where echocardiography and MRI could not differentiate between tumor and thrombus.
