    Notes: Abstract Gallium-67-citrate scanning was performed in 9 patients with ulcerative colitis. In all patients there was good correlation between the regional uptake of gallium and the extent and activity of disease. In 2 patients the scans were positive during an acute exacerbation and reverted to normal or near normal during clinical remission. In one patient in whom the colon was resected because of toxic dilatation, good correlation was found between pathologic and scintigraphic examinations. During the acute attack of ulcerative colitis, when colonoscopy or barium enema may be contraindicated, gallium scanning may be a noninvasive means of assessing the extent of colonic involvement. It may also be an alternative means of following the clinical course of the disease.

    Notes: Abstract Thirty-five patients with acute ischaemic stroke were studied within 24 h after hospital admission with thallium 201 diethyldithiocarbamate single photon emission tomography (201TI-DDC SPET) and X-ray computed tomography (CT).201TI-DDC is a non-redistributing agent that allows postponed imaging after early administration and early therapeutic intervention. In 16 patients both investigations were performed within 24 h after stroke onset. The sensitivity of SPET was 94% and of CT 81 % in the first 24 h, when hypodensity and obliteration of sulci were used as CT reading criteria. When only hypodensity was used as a criterion, the sensitivity of CT was 50% in this group. Sensitivity of CT compared with SPET became increasingly better in patients with older infarcts (1–18 days). In two-thirds of patients, the lesion demonstrated on SPET was larger than that on CT, and this was especially so with older infarcts. Crossed cerebellar diaschisis occurred in 69% of patients. The high sensitivity of201TI-DDC SPET in the first 24 h after ischaemic stroke and the favourable properties of this radiopharmaceutical make it a method of interest in the assessment of initial perfusion defects in early experimental stroke therapies.
