A computed column is a virtual column that isn't physically stored in the table, unless the column is marked PERSISTED. A computed column expression can use data from other columns to calculate a value for the column to which it belongs. You can specify an expression for a computed colum...
the entire volume is still covered. This allows a faster scan with a lower radiation burden to the patient but certainly compromises image quality. A balance between image quality and the speed of acquisition should be maintained. In another example, if the table moves 4 mm in one rotation an...
(table s1). it is clear that further increment of cu1.94s dosage causes a negligible enhancement of pce. therefore, to obtain simultaneously desired ct imaging and photothermal ablation efficacy, the ratio of cu-to-bi in the ncs was confirmed and set at 17.2:1. it is noteworthy that the ...
In contrast toDXA, quantitativecomputed tomography(QCT) measures true volumetric BMD, but the dose of radiation is high (30−7000 μSv) (Table 1).22Measurements of the spine and hip are obtained using a clinical whole-body scanner equipped with special analysis software. QCT machines are cost...
Table 2shows the results of the quantitative RT-MCE analysis at baseline and during dipyridamole in the different stenosis severity groups. At baseline, no significant differences in A, beta, or A × beta were noted among the groups. With dipyridamole, beta and A × beta increased in all but...
