Visualization of cerebral and vascular abnormalities by NMR imaging. The effects of imaging parameters on contrast.

Abstract

The relationship between data acquisition parameters and contrast in NMR images [in humans] was studied. NMR imaging by the pulse echo technique selectively enhanced intracranial abnormalities; imaging by the inversion recovery technique heightened the difference between cerebral gray and white matter. Using a blood fow model, it was also demonstrated that NMR imaging of flow in major vessels is possible.
