Since its development in the 1970s and 1980s, MRI has proven to be a versatile imaging technique. 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. Pulses of radio waves excite the nuclear spin energy transition, and magnetic field gradients localize the polarization in space. For this reason, most MRI scans essentially map the location of water and fat in the body. Hydrogen atoms are naturally abundant in humans and other biological organisms, particularly in water and fat. In clinical and research MRI, hydrogen atoms are most often used to generate a macroscopic polarization that is detected by antennas close to the subject being examined. Certain atomic nuclei are able to absorb radio frequency energy when placed in an external magnetic field the resultant evolving spin polarization can induce a RF signal in a radio frequency coil and thereby be detected. MRI was originally called NMRI (nuclear magnetic resonance imaging), but "nuclear" was dropped to avoid negative associations. Additionally, implants and other non-removable metal in the body can pose a risk and may exclude some patients from undergoing an MRI examination safely. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, though "Open" MRI designs mostly relieve this. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. 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.

She tucked the sleeveless top into a pair of high-waisted, baggy blue drop-crotch joggers and accessorized with brown sneakers. Tucked into the super short shorts, she wore a blue sequin tan top with a silver sequin cropped jacket on top, a bedazzled white Western belt, and a pair of matching Azalea Wang Freida Embellished Bootie in White, putting her long, toned legs on display.Īnother one of our favorite recent looks from the country singer was her white tank top that read, “Sweaxy” in bright red letters.
