超声、磁共振和核医学成像的发展现状和趋势

THE PRESENT STATE AND FUTURE DEVELOPMENT OF ULTRASOUND, MAGNETIC RESONANCE AND NUCLEAR MEDICAL IMAGINGS

超声、磁共振和核医学成像是独立于 X射线成像以外的三种医学影像技术。高档超声成像设备已经进入了采用数字多声道技术来提高成像的分辨率和实时性的时代 ,新兴的磁共振成像技术通过对磁场和表面线圈的改进、创新 ,其成像分辨率和实时性已经可以和 X射线CT一比高下 ,而对核医学来说传统的 γ照相机正在让位给发射型计算机体层 CT(SPECT)和正电子发射型 CT(PET)

Ultrasound, magnetic resonance and nuclear medical imagings are three independent medical imaging technologies different from X ray imaging. The superb ultrasound diagnostic equipment has advanced to a stage of utilizing digital multi channel technology. With the improvement of coil and magnetic field, the resolution and real time of the magnetic resonance imaging have almost become as powerful as X ray CT. As for the nuclear medical imaging, the traditional γ camera is giving way to the single photon emission computed tomography (SPECT) and position emission computed tomography.
