Dual-source CT for tears of thoracic aortic dissections assessment:a controlled trial
AIM:To assess the diagnostic accuracy of a dual-source CT ( DSCT) protocol for preoperative revealing of the tears of thoracic aortic dissections ( TAD). METHODS: From January to October of 2008,139 consecutive patients with suspected TAD were enrolled in this trial by comparing DSCT with other imaging modalities,including digital subtraction angiography ( DSA),transthoracic echocardiography ( TTE ),64-slice multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI). RESULTS: Ninety-seven patients were diagnosed as having TAD. The samples of DSCT,DSA,TTE,MDCT and MRI were 112,72,94,60 and 6,respectively. The diagnosis sensitivity was 95% for TTE (P<0.05),93% for MDCT (P<0.05),and 100% for DSCT,DSA and MRI. The diagnostic accuracy for preoperative revealing of the tears of TAD of DSCT,DSA,TTE and MDCT was 98%,98%,46% ( P < 0.05 ) and 87% ( P < 0.05). Compare with DSCT,these differences had significances. CONCLUSION: The diagnostic accuracy by DSCT for preoperative revealing of tears of TAD is higher than that by others. Dual-source CT should be the first choice of imaging modalities.
