Endoscopic ultrasonography can provide us with high - resolution images of the pancreas the nearby structures , arid it is an effective imaging modality for the diagnosis of pancreatic diseases with a high specificity and sensitivity 超声内镜能够提供高分辨率的胰腺实质、导管及其邻近组织的图像,对胰腺疾病的诊断有着较高的特异性和灵敏度,是诊断胰腺疾病的一种有效的影像学方法。
In the past , to obtain information of the contractility of the heart , the physiological function and the anatomy of coronary arteries need different imaging modalities , including echocardiogram , transoesophageal echocardiography , nuclear medicine and conventional angiography 以往要检查心脏肌肉的运动、心脏的功能、冠心状动脉、必须进行多项不同的检查,包括超声波扫描、核子扫描及血管造影。
Because of its harmlessness as well as other superiorities such as its characteristics of real time and portability , which are impossible for other imaging modalities , this technique has attracted much attention and is of great value for research 由于该技术对生物组织体具有无损伤性,并且还具有其他成像技术所不具备的优点,如连续实时性和便携性等,因此光学层析成像技术已经成为研究的热点,具有很高的研究价值。
Zhou of the uniersity of pennsylania , philadelphia , and colleagues reiewed noninasie imaging modalities to track implanted cells , including magnetic resonance imaging ( mri ) , positron emission tomography ( pet ) , single - photon emission computed tomography ( spect ) , and optical imaging using luminescence and fluorescence 这包括磁共振影像学( mri ) ,正电子发射断层扫描术( pet ) ,单光子发射计算体层摄影术( spect )和使用发光和荧光的光学成像术。
Acr standard for teleradiology and acr standard for digital image data management were chosen as the reference standards for the image functions for the consultation software system , with addition of image functions for more image modality ; while dicom was proposed as the standard if the consultation system would be upgraded as a subsystem of a pacs 提出会诊系统中图像功能应参照美国放射学会的远程放射学标准和数字图像管理标准,并增加适合多种医学图像的图像功能。而dicom标准应作为会诊系统进一步发展为pacs的子系统时的标准。
