  2. Safety of magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Safety_of_magnetic...

    Despite these concerns, MRI is rapidly growing in importance as a way of diagnosing and monitoring congenital defects of the fetus because it is able to provide more diagnostic information than ultrasound and it lacks the ionizing radiation of CT. MRI without contrast agents is the imaging mode of choice for pre-surgical, in-utero diagnosis and ...

  3. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. 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. [1]

  4. Physics of magnetic resonance imaging - Wikipedia

    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 ...

  5. Nuclear medicine - Wikipedia

    en.wikipedia.org/wiki/Nuclear_medicine

    Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...

  6. In vivo magnetic resonance spectroscopy - Wikipedia

    en.wikipedia.org/wiki/In_vivo_magnetic_resonance...

    In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...

  7. Functional magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Functional_magnetic...

    In a comparison of genotoxic effects of MRI compared with those of CT scans, Knuuti et al. reported that even though the DNA damage detected after MRI was at a level comparable to that produced by scans using ionizing radiation (low-dose coronary CT angiography, nuclear imaging, and X-ray angiography), differences in the mechanism by which this ...

  8. Radiation therapy - Wikipedia

    en.wikipedia.org/wiki/Radiation_therapy

    Radiation therapy (RT) is in itself painless, but has iatrogenic side effect risks. Many low-dose palliative treatments (for example, radiation therapy to bony metastases) cause minimal or no side effects, although short-term pain flare-up can be experienced in the days following treatment due to oedema compressing nerves in the treated area ...

  9. Gel dosimetry - Wikipedia

    en.wikipedia.org/wiki/Gel_dosimetry

    The aim of the first workshop was to bring together individuals, both researchers and users, with an interest in the application of 3-dimensional radiation dosimetry techniques in the treatment of cancer, with a mix of presentations from basic science to clinical applications. This has remained an objective for all of the conferences.
