A new technique has been developed by a team of researchers at the University of York that will enhance the performance of magnetic resonance imaging (MRI) in identifying diseases.
Medical imaging techniques such as MRI and Nuclear Magnetic Resonance (NMR) use magnetic fields for generating images of different body parts. But the detection range is limited since only one molecule or nuclei is detected in every 200,000.
This limitation has been fixed by the new technique (Signal Amplification by Reversible Exchange) developed by the York team which increases the accessible magnetism of nuclei making it visible for a longer time. With this technique one out of every two molecules can be detected over minutes allowing both large and small changes in the body to be detected easily.
This technique can be efficiently used for studying heart diseases. A medical professional needs to inject a non- toxic contrast agent into the blood of the patient to be able to trace through the veins into the heart for detecting any blockages.
It will also be extremely helpful during cancer treatment. The technique can be used for identifying small tumor fragments which at times go undetected once the large tumor has been eradicated from the patient's body.
The technique has a great potential in the field of health care diagnostics.
