Paper Abstract

Preliminary results from cranial NMR examinations of 180 patients and 40 volunteers are discussed. Three different pulse sequences have been used to produce images with varying dependence on proton density, T1 and T2. Repeated Free Induction Decay (RFID) images which largely reflect proton density are rather featureless and show limited changes in disease. Inversion-recovery (IR) images whose contrast largely depends on differences in T1 show a high level of grey white matter contrast. In addition acute haemorrhage is associated with shortened values of T but many other conditions such as infarction, infection, demyelination, oedema and thalignancy are associated with increased levels of T1. Spin-echo (SE) images whose contrast largely depends on differences in T2 show very little grey white matter contrast but highlight pathological change in a variety of conditions against the bland background of the remaining brain. NMR has a number of important advantages over CT in imaging the brain and appears likely to assume an important role in neurological diagnosis.
