Abstract:
Objective To compare the diagnostic accuracy of magnetic resonance (MR) images with multislice computer tomography (MSCT) for preoperative T-staging of patients with cardiac cancer. Methods MR and MSCT were performed in 28 cases of cardiac cancer diagnosed by biopsy prior to operation within one week. After an oral intake of 1000 ml water and an injection of hypotonic agent, MR and MSCT scan were carried out. MR sequences included FSE T1W, FSE T2W, FSE T1W with fat suppression and dynamic enhanced FSPGR with fat suppression. MSCT was applied with dynamic triphasic contrast enhancement. All of the findings were prospectively analyzed by two doctors separately and compared with the surgical and pathological findings. Results According to histopathologic staging, the accuracy of MR and MSCT in T1-staging were 88.8% and 11.1%, in T2-staging were 77.8% and 22.2%, in T3-staging were 83.3% and 32.7%, in T4-staging were 100.0% and 50.0%, respectively. Dynamic enhanced and delayed MR with fat suppression was superior to MSCT for revealing the involvement of esophagus and aorta, early stage of invasiveness and providing more evidences in T2 to T3 or T3 to T4 staging (P
