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 in both health and disease. MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the organs in the body. MRI does not involve x rays, which distinguishes it from computed tomography CT or CAT. While the hazards of x rays are now well controlled in most medical contexts, MRI still may be seen as superior to CT in this regard. MRI is widely used in hospitals and clinics for medical diagnosis, staging of disease and follow up without exposing the body to ionizing radiation. MRI often may yield different diagnostic information compared with CT. There may be risks and discomfort associated with MRI scans. Compared with CT, MRI scans typically take greater time, are louder, and usually require that the subject go into a narrow, confined tube. In addition, people with some medical implants or other non removable metal inside the body may be unable to undergo an MRI examination safely. MRI is based upon the science of nuclear magnetic resonance NMR. Certain atomic nuclei are able to absorb and emit radio frequency energy when placed in an external magnetic field. In clinical and research MRI, hydrogen atoms are most often used to generate a detectable radio frequency signal that is received by antennas in close proximity to the anatomy being examined. Hydrogen atoms exist naturally in people and other biological organisms in abundance, particularly in water and fat. For this reason, most MRI scans essentially map the location of water and fat in the body. Pulses of radio waves excite the nuclear spin energy transition, and magnetic field gradients localize the signal in space. By varying the parameters of the pulse sequence, different contrasts may be generated between tissues based on the relaxation properties of the hydrogen atoms therein. Since its early development in the 1. MRI has proven to be a highly versatile imaging technique. While MRI is most prominently used in diagnostic medicine and biomedical research, it also may be used to form images of non living objects. MRI scans are capable of producing a variety of chemical and physical data, in addition to detailed spatial images. The sustained increase in demand for MRI within the healthcare industry has led to concerns about cost effectiveness and overdiagnosis. Construction and physicsedit. Schematic of construction of a cylindrical superconducting MR scanner. To perform a study, the person is positioned within an MRI scanner that forms a strong magnetic field around the area to be imaged. In most medical applications, protons hydrogenatoms in tissues containing water molecules create a signal that is processed to form an image of the body. First, energy from an oscillatingmagnetic field temporarily is applied to the patient at the appropriate resonance frequency. The excitedhydrogenatoms emit a radio frequency signal, which is measured by a receiving coil. The radio signal may be made to encode position information by varying the main magnetic field using gradient coils. As these coils are rapidly switched on and off they create the characteristic repetitive noise of an MRI scan. The contrast between different tissues is determined by the rate at which excited atoms return to the equilibrium state. Exogenous contrast agents may be given intravenously, orally, or intra articularly. The major components of an MRI scanner are the main magnet, which polarizes the sample, the shim coils for correcting inhomogeneities in the main magnetic field, the gradient system which is used to localize the MR signal and the RF system, which excites the sample and detects the resulting NMR signal. The whole system is controlled by one or more computers. MRI requires a magnetic field that is both strong and uniform. The field strength of the magnet is measured in teslas and while the majority of systems operate at 1. T, commercial systems are available between 0. T. Most clinical magnets are superconducting magnets, which require liquid helium. Lower field strengths can be achieved with permanent magnets, which are often used in open MRI scanners for claustrophobic patients. Recently, MRI has been demonstrated also at ultra low fields, i. T and by measuring the Larmor precession fields at about 1. SQUIDs. 567MRI is in general a safe technique, although injuries may occur as a result of failed safety procedures or human error. Contraindications to MRI include most cochlear implants and cardiac pacemakers, shrapnel, and metallic foreign bodies in the eyes. The safety of MRI during the first trimester of pregnancy is uncertain, but it may be preferable to other options. Since MRI does not use any ionizing radiation, its use is generally favored in preference to CT when either modality could yield the same information. In certain cases, MRI is not preferred as it may be more expensive, time consuming, and claustrophobia exacerbating. T1 and T2edit. Effects of TR and TE on MR signal. Examples of T1 weighted, T2 weighted and PD weighted MRI scans. Each tissue returns to its equilibrium state after excitation by the independent processes of T1 spin lattice and T2 spin spin relaxation. To create a T1 weighted image, magnetization is allowed to recover before measuring the MR signal by changing the repetition time TR. This image weighting is useful for assessing the cerebral cortex, identifying fatty tissue, characterizing focal liver lesions and in general for obtaining morphological information, as well as for post contrast imaging. To create a T2 weighted image, magnetization is allowed to decay before measuring the MR signal by changing the echo time TE. This image weighting is useful for detecting edema and inflammation, revealing white matter lesions and assessing zonal anatomy in the prostate and uterus. The standard display of MRI images is to represent fluid characteristics in black and white images, where different tissues turn out as follows T1 weighted. T2 weighted. Bright. Inter mediate. Gray matter darker than white matter1. White matter darker than grey matter1. Dark. Contrast agentseditMRI for imaging anatomical structures or blood flow do not require contrast agents as the varying properties of the tissues or blood provide natural contrasts. However, for more specific types of imaging the most commonly used intravenous contrast agents are based on chelates of gadolinium. In general, these agents have proved safer than the iodinated contrast agents used in X ray radiography or CT. Anaphylactoid reactions are rare, occurring in approx. Of particular interest is the lower incidence of nephrotoxicity, compared with iodinated agents, when given at usual dosesthis has made contrast enhanced MRI scanning an option for patients with renal impairment, who would otherwise not be able to undergo contrast enhanced CT. Although gadolinium agents have proved useful for patients with renal impairment, in patients with severe renal failure requiring dialysis there is a risk of a rare but serious illness, nephrogenic systemic fibrosis, which may be linked to the use of certain gadolinium containing agents. The most frequently linked is gadodiamide, but other agents have been linked too. Although a causal link has not been definitively established, current guidelines in the United States are that dialysis patients should only receive gadolinium agents where essential, and that dialysis should be performed as soon as possible after the scan to remove the agent from the body promptly. In Europe, where more gadolinium containing agents are available, a classification of agents according to potential risks has been released.
