科學(xué)家已經(jīng)設(shè)計(jì)了一種完全非創(chuàng)傷性的影像檢查方法，具有核磁共振(MRI)的效果，但是免除了患者暴露于輻射的危險(xiǎn)，從而創(chuàng)造了一種新型輕便靈活的MRI工藝。

Alexej Jerschow博士是紐約大學(xué)(New York, NY, USA)的生理化學(xué)助理教授，Norbert Müller博士是Linz大學(xué)(Austria)的生理有機(jī)化學(xué)教授，他們?cè)O(shè)計(jì)了一種低能量、非侵入的核子磁共振(NMR)工藝，該工藝無(wú)需外源性輻射波(RF)輻射。他們的檢測(cè)工藝依賴(lài)于使用高度藕聯(lián)的RT天線線圈，檢測(cè)自發(fā)的質(zhì)子旋轉(zhuǎn)-噪音。

MRI給了臨床醫(yī)生通過(guò)使用RG放射方法從體外非侵入性觀察體內(nèi)軟組織的情況。但是MRI的RF脈沖在患者和工作人員體內(nèi)產(chǎn)生了熱量，盡管安全法規(guī)已經(jīng)規(guī)定了能量堆積的界限。

Non-invasive Imaging Better Than Standard MRI
 
Scientists have devised a totally non-invasive imaging method that provides the benefits of magnetic resonance imaging (MRI) while eliminating patients’ exposure to irradiation and creating the possibility of developing light, mobile MRI technology.

Dr. Alexej Jerschow, an assistant professor of physical chemistry at New York University (New York, NY, USA), and Dr. Norbert Müller, a professor of physical organic chemistry at the University of Linz (Austria), have devised a low-energy, non-invasive nuclear magnetic resonance (NMR) technique that does not require external radiofrequency (RF) irradiation. Instead, their method relies on the detection of spontaneous, proton spin-noise in a tightly coupled RF antenna coil.

MRI allows clinicians to non-invasively visualize soft tissue in the interior of the human body by applying RF irradiation. However, the MRI’s RF pulses deposit heat in patients and medical personnel, although safety regulations that limit energy deposition have long been established.
