Single photon emission computed tomography (SPECT) was used to study redistribution of N-isopropyl-[123I]-p-iodoamphetamine (IAMP) in 10 patients with intracerebral haemorrhage and 7 with ischaemic stroke. Delayed/early IAMP uptake ratios (D/E) were calculated for four different cerebral zones: haematoma or infarct, perilesional, normal and crossed(More)
Value, indication and limits of serial and static brain radioangiogram in carotid disease are studied comparatively with EEG, Doppler study and cerebral arteriography. The isotopic study shows the occlusion and its consequences on middle cerebral artery and cerebral hemisphere. The "Hot-Nose" sign is rarely seen, but then with large focal abnormalities. In(More)
A fast diagnosis (6 h) of clinically latent pyonephrosis by combined use of 99mTc-MDP and 67Ga-citrate is reported. This technique combines the potential early detection of focal infectious processes by 67Ga and the ‘high-pulse’ separation possibility of multiple isotopes. A brief prospective study (6 months) showed the interest of this technique: in six(More)
The visualization of the cerebral ventricles during a brain scan is a relatively rare possibility. The authors had the opportunity of observing four cases. They report them and discuss the 19 cases reported in world literature. There were, in order of importance, 12 cases of ventriculitis, 3 of non tumorous intraventricular erruptions, 2 of tumorous(More)
