MP joint implant is a unique three-piece implant system for the primary reconstruction of the metatarsal phalangeal joint resulting from osteoarthritis, rheumatoid arthritis, traumatic arthritis or revision of a previous arthroplasty. The implant is designed to achieve three goals such as pain relief, superior function, and longevity.

There are two principal classes of MRI contrast agents such as paramagnetic and superparamagnetic compounds. Paramagnetic agents primarily shorten the T1 relaxation time of the tissue, in which they accumulate. It is based on metal ions with one or more unpaired electrons. Superparamagnetic agents consist of magnetic nanoparticles of iron oxide coated with a polymer matrix such as dextran. These MRI contrast agents work by affecting the time it takes for the hydrogen atoms to return to their original energy state. This increases the difference in the signal intensity from the two types of tissue (the one with and the other without the contrast agent), thus increasing the degree of contrast on the image.

MRI contrast media works by affecting the time it takes for the hydrogen atoms to return to their original energy state. This increases the difference in the signal intensity from the two types of tissue (the one with and the other without the contrast agent), thus increasing the degree of contrast on the image. It contains the heavy metal gadolinium, which is encapsulated within a ligand, and this makes the gadolinium less toxic and also ensures that the CM remains in the bloodstream.

Magnetic Resonance Imaging (MRI) is a medical imaging technique primarily used in Radiology to visualize the structure and function of the body. It provides detailed images of the body in any plane. MRI provides much greater contrast between the different soft tissues of the body than does computed tomography (CT), making it especially useful in neurological (brain), musculoskeletal, cardiovascular, and oncological (cancer) imaging. Unlike CT it uses no ionizing radiation, but uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body. Radiofrequency fields are used to systematically alter the alignment of this magnetization, causing the hydrogen nuclei to produce a rotating magnetic field detectable by the scanner. This signal can be manipulated by additional magnetic fields to build up enough information to reconstruct an image of the body. Magnetic resonance imaging was developed from knowledge gained in the study of nuclear magnetic resonance.

MRI Imaging is an imaging technique that employs radio frequency waves instead of X-rays. MRI imaging provides the best soft tissue detailing of all the diagnostic modalities. It is also helpful in determining the presence of cervical lymph nodes. MRI imaging can be used to assess the size of the hippocampus and to detect progressive cortical atrophy in AD. MRI imaging provides a unique view into the interior of the human body and has become an essential tool of modern medical imaging & disease diagnosis.
