Test-Retest Reliability of Continuous Arterial Spin Labeling of Normal Parotid Glands
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
Purpose :To compare the test-retest reproducibility of three scans for continuous arterial spin labeling (CASL).Materials and methods:In this prospective study, eight healthy subjects were scanned on 3.0 T scanner with CASL. Three scans were performed at two intervals, i.e 20 minutes and 1 week, reproducibility of continuous arterial spin at different intervals were observed , by two different readers . Results:The average value for blood flow measurements of the parotid gland for tow readers were (0min 52.09895 , 20min 54.78945 , 1week 55.13335) , Intra-observer and inter-observer data were assessed by calculating the percent coefficient of variation (% CVs) of BF(Blood Flow) after the same or other radiologists repeatedly placed ROIs(Region of Interest) on the gland areas. Conclusion:The precision of CASL technique in measuring the blood flow of parotid gland makes it an interesting and considerable method of choice for clinical application of ASL in the future.
