    Insights

    Postmortem MRI offers new possibilities for brain examination and diagnosis. This technique can reveal subtle changes and aid in understanding disease pathology in fixed brain specimens.

    Area of Science:

    • Neuroimaging
    • Pathology
    • Forensic Medicine

    Background:

    • Postmortem examination of the brain is crucial for diagnosing neurological diseases.
    • Traditional methods may miss subtle or macroscopic undetectable pathological changes.

    Purpose of the Study:

    • To evaluate the potential of postmortem Magnetic Resonance Imaging (MRI) for brain examination.
    • To explore MRI's utility in diagnosing neurosurgical pathologies in fixed specimens.

    Main Methods:

    • Utilized 21 neutral formalin-fixed gross brain specimens from neurosurgery patients.
    • Performed macroscopic and targeted histological studies on MRI-identified signal areas.
    • Employed histochemical stains for detailed tissue analysis.

    Main Results:

    • Postmortem MRI effectively identified signal alterations in fixed brain specimens.
    • Histological correlation confirmed the significance of MRI-detected changes.
    • The technique demonstrated potential for detecting macroscopically undetectable changes like perifocal alterations and metastases.

    Conclusions:

    • Postmortem MRI is a valuable tool for in vitro brain examination and diagnosis.
    • It offers significant opportunities for diagnosing various diseases and understanding disease substrates.
    • MRI can address complex diagnostic challenges and reveal subtle pathological findings.

    Magnetic Resonance Imaging

    Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

    Brain Imaging

    Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
    These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
