  2. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.

  3. Bone scintigraphy - Wikipedia

    en.wikipedia.org/wiki/Bone_scintigraphy

    A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis , location of bone inflammation and fractures (that may not be visible in traditional X-ray images ), and bone infection (osteomyelitis).

  4. Skeletal survey - Wikipedia

    en.wikipedia.org/wiki/Skeletal_survey

    The standard set of X-rays for a skeletal survey includes X-rays of the skull, entire spine, pelvis, ribs, both humeri and femora (proximal long bones). It is more effective than isotope scans at detecting bone involvement in multiple myeloma. Although significantly less sensitive than MRI, it is easier to include more bones. A study found that ...

  5. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    One frame of an MRI scan of the head showing the eyes and brain A magnetic resonance imaging instrument ( MRI scanner ), or "nuclear magnetic resonance ( NMR ) imaging" scanner as it was originally known, uses powerful magnets to polarize and excite hydrogen nuclei (i.e., single protons ) of water molecules in human tissue, producing a ...

  6. Legg–Calvé–Perthes disease - Wikipedia

    en.wikipedia.org/wiki/Legg–Calvé–Perthes...

    A bone scan or MRI may be useful in making the diagnosis in those cases where X-rays are inconclusive. Usually, plain radiographic changes are delayed six weeks or more from clinical onset, so bone scintigraphy and MRI are done for early diagnosis. MRI results are more accurate, i.e. 97–99% against 88–93% in plain radiography.

  7. T2*-weighted imaging - Wikipedia

    en.wikipedia.org/wiki/T2*-weighted_imaging

    T 2 *-weighted sequences are very useful for evaluation of articular cartilages and ligaments because a relatively long T 2 * makes the articular cartilage becomes more hyperintense, while bone becomes hypointense. [2] T 2 *-weighted sequences can be used with MRI contrast, mainly ferucarbotran or superparamagnetic iron oxide (SPIO), to depict ...

    Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...

  9. Occult fracture - Wikipedia

    en.wikipedia.org/wiki/Occult_fracture

    The vertical parasagittal planes correspond to the region of maximal stress during walking, while the horizontal fracture develops later, secondary to the loss of lateral support by parasagittal fractures. MRI is the primary imaging technique in this case, with the most common MRI pattern showing bone marrow edema and a fracture line (Figure 12).
