Interventional magneticresonanceimaging , also Interventional MRI or IMRI , is the use of magneticresonanceimaging MRI to do interventional radiology procedures. Because of the lack of harmful effects on the patient and the operator, MR is well suited for interventional radiology , where the images produced by an MRI scanner are used to guide a minimally invasive procedure intraoperatively and or interactively. However, the non magnetic environment required by the scanner and the strong magnetic radiofrequency and quasi static fields generated by the scanner hardware require the use of specialized instruments. For example, use of non magnetic e.g. Titanium surgical instruments and MR compatible patient surveillance accessories in addition to the costly MRI scanner increase the cost of IMRI. Often required is the use of an open bore magnet, which permits the operating staff better access to patients during the operation. Such open bore magnets are often lower field magnets, typically in the 0.2 tesla range, which decreases their sensitivity tests sensitivity and Time temporal efficiency but also decreases the Radio Frequency Effective radiated power power potentially absorbed by the patient during a protracted operation. Higher field magnet systems are beginning to be deployed in intraoperative imaging suites, which can combine high field MRI with a surgical suite and even computed tomography CT in a series of interconnected rooms. Specialty high field interventional MR devices, such as the IMRIS system, can actually bring a high field magnet to the patient within the operating theatre, permitting the use of standard surgical tools while the magnet is in an adjoining space.

Introduction Event related functional magneticresonanceimaging efMRI Event related fMRI is a fairly new technique that can be used to detect changes in the BOLD Blood Oxygen Level Dependent hemodynamic response to neural activity in response to certain events ref Henson ref . Within fMRI methodology there are two different ways that are typically employed to present stimuli. One of which is a block related design, in which two or more different conditions are alternated in order to determine the differences between the two conditions or a control may be included in the presentation occurring between the two conditions. Event related designs on the other hand are not presented in a set sequence, the presentation is randomized and the time in between stimuli can vary. efMRI attempts to model the change in fMRI signal in response to neural events associated with behavioral trials. According to D Esposito ref D Esposito ref event related fMRI has the potential to address a number of cognitive psychology questions with a degree of inferential and statistical power not previously available. Each trial can be composed of one experimentally controlled such as the presentation of a word or picture or a participant mediated event such as a motor response . Within each trial there are a number of events within each trial such as the presentation of a stimulus, delay period, and response. If the experiment is properly set up and the different events are timed correctly, efMRI allows you to observe the differences in neural activity associated with each event.

Magneticresonance elastography MRE is a non invasive medical non invasive medical imaging technique that measures the mechanical properties stiffness of soft tissues by introducing shear wave s and imaging their propagation using MRI . Pathological tissues are often harder than the surrounding normal tissue, for instance, malignant breast tumors are much harder than healthy fibro glandular tissue. This characteristic has been used by physicians for screening and diagnosis of many diseases, through Palpation . MRE calculates the mechanical parameter as elicited by palpation, in a non invasive and objective way.

Chemical shift Main Chemical shift A spinning charge generates a magnetic field that results in a magnetic moment proportional to the spin. In the presence of an external magnetic field, two spin states exist for a spin 1 2 nucleus one spin up and one spin down, where one aligns with the magnetic ... more details

NMR coupling refers to the effect of nuclei on each other in atoms within a couple of bonds distance of each other in molecules. This effect causes NMR signals in a spectrum to be split into multiple peaks which are up to several hertz frequency from each other. Decoupling fully or partially eliminates splitting of the signal between the nuclei irradiated and other nuclei such as the nuclei being analyzed in a certain spectrum. NMR spectroscopy and sometimes decoupling can help determine Chemical structure structures of chemical compound s. Explanation NMR spectroscopy of a sample produces an NMR spectrum, which is essentially a graphics graph of signal intensity on the vertical axis vs. chemical shift for a certain isotope on the horizontal axis. The signal intensity is dependent on the number of exactly equivalent nuclei in the sample at that chemical shift. NMR spectra are taken to analyze one isotope of nuclei ... in in vivo magneticresonance spectroscopy . ref name CESTreview cite journal author Sherry AD, Woods ... 13 sup C coupling effect does show up on non sup 13 sup C decoupled spectra of other magnetic ... also be off resonance decoupling of sup 1 sup H from sup 13 sup C nuclei in sup 13 sup C NMR ....
