Thus combined imaging of DAT and D 2R may provide a valuable information for clinical and differential diagnosis of PD and assessment of the magnitude of degeneration of nigrastriatum.
ResultsThe diagnostic accuracy by four modalities in group M, which were whole body bone scan, bone SPECT, bone CT and fusion imaging, was 51.7%, 93.1%, 89.7% and 100% ; in group B was 32.7%, 60.0%, 92.7% and 94.5%, respectively. ConclusionsSPECT/CT using 99Tcm-MDP is clinically valuable in differentiating malignancy from benignancy in spine diseases.
Also, the experiments prove that it is feasible to use the method to develop a domain automatic abstracting system, which is valuable for further in-depth study.
The cationic complex 99mTc hexakis(t-butylisonitrile)-technetium (Ⅰ)[99mTc TBI] is a valuable myocardial imaging agent for myocardial ischemia and infarc tion.99mTc-TBI is prepared by ligand exchange reaction between 99mTc-GH and TBI.The ligand exchange reactions are studied at different pH values, time, TBI and calcium glucoheptonate concentrations. The exchange yield is determined by paper chromatography and reaction rate constants are calculated at different pH values.The results obtained show that...
We presented the study of measuring 'myocaridal infarct size' (Mls)in cardiac phantom made by ourselves with SPECT. We used two methods, relative pixel quantification method (RPOM) and relative angle quantification method (RAQM), to size infarets(in %)from the short axis profiles of myocardial SPECT. There is an good correlation between the actual Mis and the Mis measured by RPQM and RAQM(r - 0. 978 and 0. 987, respectively, both p<0. 01 ). The actual Mis is different from the size by RPQM.but not different...
12 football players with a average age of 23yrs and the weight of 65kgs volunteered to participate in thestudy. At 8 AM, the subjects exercised on a bicycle ergometer at 65% of their VO_2 max for 10 minutes. 9serial matched samples of salivary and antecubital vein blood were obtained before exercise (O'), after 10',20', 30', 40', 50', 60', 90', and 120' of exercise. Salivary and plasma cortisol levels were determined bydirect radioimmunoassay. Significant linear correlations were obtained between plasma and...
