Magnetic resonance cholangiopancreatography [PDF]
Gut, 1997 Non-invasive imaging techniques such as ultrasound (US) or computed tomography (CT) are widely used for the diagnosis and monitoring of many pancreatic and biliary tract diseases. However, these techniques have limitations, such as the low sensitivity of ultrasound for detecting common duct calculi, which means that the diagnosis of several common ...

Magnetic Resonance Sensors [PDF]
Sensors, 2014 Magnetic Resonance finds countless applications, from spectroscopy to imaging, routinely in almost all research and medical institutions across the globe. It is also becoming more frequently used for specific applications in which the whole instrument and system is designed for a dedicated application.

Magnetic resonance fingerprinting [PDF]
Nature, 2013 Magnetic resonance is an exceptionally powerful and versatile measurement technique. The basic structure of a magnetic resonance experiment has remained largely unchanged for almost 50 years, being mainly restricted to the qualitative probing of only a limited set of the properties that can in principle be accessed by this technique.

Magnetic Resonance Elastography [PDF]
Current Medical Imaging Reviews, 2012 Often compared to the practice of manual palpation, magnetic resonance elastography is an emerging technology for quantitatively assessing the mechanical properties of tissue as a basis for characterizing disease. The potential of MRE as a diagnostic tool is rooted in the fact that normal and diseased tissues often differ significantly in terms of ...

Magnetic resonance cholangiopancreatography [PDF]
Journal of Magnetic Resonance Imaging, 1999 Magnetic resonance cholangiopancreatography (MRCP) uses MR imaging to visualize fluid in the biliary and pancreatic ducts as high signal intensity on T2-weighted sequences; it is the newest modality for biliary and pancreatic duct imaging. MRCP is of proven utility in a variety of biliary and pancreatic diseases, including choledocholithiasis ...

Cardiovascular Magnetic Resonance [PDF]
Circulation, 2001 Cardiovascular magnetic resonance (CMR) creates images from atomic nuclei with uneven spin using radiowaves in the presence of a magnetic field. Full details of the physical principles can be found elsewhere.1 For clinical purposes, MR is performed using hydrogen-1, which is abundant in water and fat. Radiofrequency waves excite the area of interest to

THz spectroscopy in the pseudo-Kagome system Cu3Bi(SeO3)2O2Br
, 2012 Terahertz (THz) transmission spectra have been measured as function of temperature and magnetic field on single crystals of Cu3Bi(SeO3)2O2Br. In the time-domain THz spectra without magnetic field, two resonance absorptions are observed below the magnetic
