Craniopharyngioma, an intracranial tumor, exhibits hyperintensity in the Spin-Echo-T2-NMR image and a hyposignal in the SE-T1-image. However, in some cases (15–20% cases), hypersignals are seen in both SE-T1 and T2-MRI. Using spectroscopic techniqu

Positron emission tomography (PET) was used to assess possible pancreatic disease in 100 patients. Following injection of 10-15 mCi (370-740 MBq) of 11C-L-methionine, 4-12 transverse sections 2 cm thick were obtained. In 85 patients with a definite d

The influence of specific activity was studied for a radiopharmaceutical labelled with a short-lived element, taking part in an enzymatic reaction or fixing onto a specific receptor. The two extreme cases where the concentration of the product is eit

TDPAC measurements of the 356-81 keV gamma-ray cascade resulting from electron capture decay of 133Ba have been performed at room temperature on BaCl2 (aqueous solution and polycrystalline powder), and on samples where the 133Ba nucleus is bound to b

Metabolic phenomena can be studied and measured non-invasively using positron emitting radionuclides and a suitably adapted tomographic system. The choice of a single slice ring camera is justified by its physical performance, which is presented here

The positron emitter 11 C (20 minutes half-life) permits the labeling of chlorpromazine (CPZ) and the study of its distribution in humans by external counting. Trace amounts of 11 C-CPZ were injected intravenously into 22 schizophrenic patients all u

The study of variations in the Mössbauer spectrum of X-irradiated arterial red cells as a function of dose shows that irradiation of red cells oxyhemoglobin leads to the production of a ligand free deoxy form, probably fast-reacting as in the well-k

Ferritin, mammalian iron reserve protein, is made of a ferric hydroxide core enclosed in a protein shell. Several Mössbauer spectrometry studies have been carried out on ferritin molecules extracted from horse spleen. They demonstrate the existence
