Time activity curves in various ROIs.
(A) Mean tissue time-activity curves expressed as standardized uptake values (SUV) for 20 scans in 10 subjects. (B) Mean tissue time-activity curves of various volumes within the thalamus, expressed as standardized uptake values (SUV) for 20 scans in 10 subjects. (C) Mean tissue time-activity curves of various volumes of white matter expressed as standardized uptake values (SUV, 20 scans in 10 subjects).
Fig 2.
Image-derived input function characteristics.
(A) Time activity curves of the image-derived input function with test-retest studies were shown. There was no significant difference (p = 0.001). (B) It was shown area under the curves of IDIF with test-retest studies and was not shown any significant difference.

Illustrate correlation of values of LGM_VT between test and retest.

Reference tissue curve characteristics.
(A) Mean TAC curves for the reference curves between test-retest studies (n = 6). (B) Mean AUC of the reference curves between test and retest.

Test-retest variability of chronic lesions in MS patients (n = 53).
(A) Graph of the test-retest variability of the VT versus BPND measures of PK in chronic MS lesions. (B) It shows the percent variability of the LGM-VT measures of PK in 53 chronic MS lesions.
