Thallium-201 SPECT of adjacent intracranial tumours: a contrast in thallium kinetics

Abstract

We report a case of adjacent intracranial tumours: malignant fibrous histiocytoma (MFH) and meningioma. Thallium-201 single-photon emission computed tomography demonstrated different thallium kinetics between the tumours (slow washout from the MFH and rapid clearance in the meningioma) and could be said to have been useful for preoperative histological estimation.

“…Whatever the mechanisms, damage to genetic material was demonstrated in thallium-poisoned people. 119 Single proton emission computed tomography (SPECT), especially using 201 Tl, is a very important medical imaging technique, many publications in this ¢eld were noted for 1999, for example for measuring tumours, 120 and in the prognosis of coronary heart disease. 121 This burgeoning use calls for more studies of the background bioinorganic chemistry of thallium so that the distribution of the element in the human body can be better understood.…”
