Radiology
Martin 23
Several radiological techniques are routinely used to image the living human brain.
Computerized tomography (CT)
Produces scans that are images of a singale plane, or "slice," of tissue. The image produced is a computerized reconstruction of the degree to which different tissues absorb transmitted x-rays. Although CT scans are commonly used cliniallly to reveal intracranial tumors and other pathological changes, the overal level of anatomical resolution is poor.
Magnetic resonance imaging (MRI)
Probes the regional anatomy of the brain in remarkably precise detail. Magnetic resonance images reveal primarily differences in th ewater content of tissue.
