| Objective To explore the basic method and clinical application of spatio-temporal image correlation (STIC) in the routine scanning of normal fetal heart.Methods Totally 120 volume datasets of normal fetal heart were acquired by 2D and STIC, respectively.The difference in time between the two methods were compared and the basic imaging method was explored and analyzed.Results Satisfactory gray-scale volume acquisitions were accomplished in 120 cases. The quality of the images derived from volume datasets were comparable to that directly obtained from 2D echocardiography. The visualization rate had no significant difference between the two methods (P>0.05).Some views that can not be showed by 2D could be acquired by STIC. The STIC sweep and routine sonography took (4.47±2.32)minutes per case (104 cases) vs (5.26±2.01) minutes per case (85 cases) respectively in fetal heart screening.Conclusion STIC provides us more views and information than 2D, simplifies the picture-gathering process, decreases the dependence of examiner, and increases the efficiency. Also, STIC provides us a time-saving sweep for fulfilling fetal cardiac screening and decreases the exposure upon fetal heart obviously. |
