- W2352783005 abstract "Objective To evaluate the clinical value of 64-slice spiral CT image post-processing techology in the diagnosis of coronary artery stenosis disease.Materials and methods 63 cases of patients with coronary heart disease is performed with coronary artery CT examination.The image is reconstructed with CPR,MPR,MIP and VR technology,and the narrow parts are analysed and diagnosed according the post-processing images.Results were compared with Coronary artery angiography.Results Diagnosis sensitivity and specificity of different degrees of coronary stenosis by MPR and CPR is 90% above,whie it is hard to show the complicated space structure.The smaller patches is easily misdiagnosed in MIP pictures though the sensitivity of the MIP reached more than 81%,specificity is 90% above.Diagnosis sensitivity of coronary stenosis of VR image is low,especially severe?stenotic vessels and block blood vessels,but the image is three-dimensional visual accurate lifelike.Negative predicted value of various methods of the image post-processing is higher than the positive,achieve 91% above.Conclusion Different post-processing technologies in displaying the coronary artery have its own advantages and disadvantages,only by combining with each other and complementing with each other,can we make a clear diagnosis." @default.
