[Magnetic tomography of intracranial hemorrhage. A study of paramagnetic effects].
The signal intensity of a hematoma at MRI is largely determined by the presence of paramagnetic substances derived from hemoglobin. Depending upon their structure and molecular mobility, paramagnetic substances may shorten the T1 and T2 of surrounding water protons and thus alter the MRI signal intensity and contrast. The article describes the evolution of intracranial hematomas and explains the relationship between the paramagnetic substance present and the resultant signal intensity at 1.5 T.
