“…To assess the feasibility of AH clustering method for AIF detection, a simulation study was also conducted in the same manner proposed by Peruzzo et al [1] and Wu et al [21], where a ‘true’ and a ‘false’ AIF was modeled. Partial volume effect (PVE) was simulated using three kinds of tissues, normal gray matter (GM), normal white matter (WM) and pathological GM.…”

“…A recirculation process was added that comprised a copy of the aforementioned function with a delay of , which was convolved with an exponential with a time constant of . We used values of  = 3.0,  = 1.5 s,  = 8 s,  = 30 s [1], [6], [8], [16], and  = 26 s, which approximated the arrival time of the contrast agent in our clinical perfusion data.…”

“…2, a set of 3D TOF-MRA (Time-of-Flight magnetic resonance angiography) images were first obtained by DCE-MRI in order to monitor the position of the middle cerebral artery (MCA) in the rat's brain [21]. The parameters of the TOF-MRA were the number of slices  = 160, TR/TE  = 14/5.42 ms, flip angle  = 20°, slice thickness  = 0.3 mm, FOV  = 85×85 mm 2 , matrix  = 256×256, slab = 5, and scanning time  = 10 min 27 s.…”
