Presentation transcript:

Montage of lesions demonstrated by MRI Montage of lesions demonstrated by MRI. The left side of the patient’s brain is to the reader’s right. All horizontal scans are mounted with the frontal lobes up. (A) MRI, horizontal T2-weighted section of the brain, shows a subacute infarct (arrow) in the left thalamus. (B) MRI, horizontal T2-weighted section of the cerebrum, shows multiple areas of periventricular demyelination (arrows) in multiple sclerosis. (C) MRI, horizontal T1-weighted section of brain, gadolinium enhanced, shows an astrocytoma with cystic cavities (arrows). The tumor is bright, and the fluid-filled cysts and CSF are black in T1-weighted images, in contrast to bright areas in T2-weighted images. (D) MRI, horizontal T1-weighted section of the brain, shows bilateral subdural hematomas (arrows) and atrophic cerebrum with enlarged ventricles and subarachnoid spaces. The patient, a battered child, had received multiple head injuries. (E) MRI, sagittal T1-weighted section of the brain. The medial wall of the hemisphere shows severe atrophy of the frontal lobe gyri, with extreme widening of the sulci. Notice the normal size of the gyri and sulci in the parts of the cerebrum posterior to the white marker. The patient has a form of dementia called Pick disease. MRI = magnetic resonance imaging.
