Magnetic Resonance Imaging. (MRI) MRI uses the detection of radio frequency signals produced by displaced radio waves in a magnetic field. It provides an anatomical view of the brain. Advantages: No X-rays or radioactive material is used. Provides detailed view of the brain in different dimensions. Safe, painless, non-invasive.

In this book, the theoretical aspects of the principles of MRI are deliberately simplified and the text can be used solely as an atlas. In the introduction, useful general features of MRI interpretation are described and itemized, and major diseases of the central nervous system are presented.Primary central nervous system lymphoma (PCNSL) is a rare and aggressive extranodal non-Hodgkin lymphoma (NHL). It is confined to the brain, eyes, spinal cord, or leptomeninges without systemic involvement at the time of diagnosis. It accounts for up to 1% of NHL cases and approximately 2% of all primary central nervous system (CNS) tumors.

MRI does not use radiation, as do X-rays or CT scans. The MRI machine is a large, tube-shaped machine that patients lie within, and the MRI creates a strong magnetic field around the patient. The magnetic field and related pulses of radio waves produce signals from the body that are detected and converted into images by a computer.

Primary central nervous system lymphoma (PCNSL) is an extra-nodal lymphoma that shows no lesions other than in the central nervous system at the time of diagnosis [].While the disease is relatively rare, comprising 1-5% of brain tumors, the number of PCNSL cases is increasing recently [2, 3].PCNSL is frequently found in association with acquired immunodeficiency syndrome (AIDS) in western ...

    The nervous system is the part of the body that coordinates voluntary and involuntary actions and transmits signals to and from different parts of its body. It detects and responds to changes inside and outside the body. Along with the endocrine system, the nervous system controls the vital functions of the body and maintains homeostasis.The nervous system is the part of the body that coordinates voluntary and involuntary actions and transmits signals to and from different parts of its body.
