Magnetic resonance imaging mri is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body mri scanners use strong magnetic fields magnetic field gradients and radio waves to generate images of the organs in the body mri does not involve x rays or the use of ionizing radiation which distinguishes it from ct and pet scans. Current status and future prospects the basic principles and current status of proton nuclear magnetic resonance imaging are outlined nuclear magnetic resonance images of the heart have improved in quality with advances in technique and better gating but clinical experience remains very limited myocardial infarction has been shown in . Nuclear magnetic resonance signals stem from the interaction of radiowaves with the atomic nuclei themselves this is the reason for the completely dif fe rent imaging equip ment necessary and the different contrast behavior of mag ne tic re so nan ce imaging as com pa red with other medical imaging techniques. The establishment of improved technologies for imaging of the pancreas is a key element in addressing several aspects of diabetes pathogenesis magnetic resonance imaging nmri nuclear magnetic resonance imaging approaches for imaging islets recent advances and future prospects in islam m eds the islets of langerhans advances in . Nuclear magnetic resonance nmr is a method of physical observation in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field in the near field and therefore not involving electromagnetic waves and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus
