Description

<p>The QSPECT dual table autoradiography (DTARG) method can be used for quantitative determination of cerebral blood flow. We verified the influence on quantitative values obtained for cerebral blood flow in the case when usual acquisition was impossible and evaluated those values. Results obtained with an acquisition time of 30 min were considered to be true values, and the correlation and consistency with results of other times were evaluated. Values obtained with a shortened acquisition time showed a high correlation with the true value. As for consistency, there were differences among the various data collection intervals. Nevertheless, regardless of the use of a shortened acquisition time and the data acquisition interval, values obtained with the QSPECT program showed a high correlation with the true value. Based on our findings showing a high correlation, a quantitative evaluation of cerebral blood flow can be performed with the QSPECT DTARG method, even with complications, such as examination interruption, thus, it is considered to be a flexible method.</p>
