This range is frequently measured since measurements at both locations can be obtained simultaneously on a single 2D acquisition at the level of the bifurcation of the pulmonary artery. In the study by Kutty et al. Deep learning methods are rapidly being incorporated into clinicalsoftware analysis packages [2, 3]. In cases where the original manuscript did not provide sufficient information to allow upper and lower limits to be calculated, authors were contacted for clarification. arXiv preprint. 2010;12:69.

Adenosine and regadenoson have similar hemodynamic effects on coronaryartery blood flow [188]. The most important parameter calculated from these parameters is stroke volume (ml) which is defined as the mean volume of CSF passing through the aqueduct in craniocaudal and caudocranial direction (Fig. Am J Clin Pathol.

CAS MBF (in units of mL/min/g) should be independent of the specific perfusion imaging protocol settings. In the absence of such data however, the weighted mean values and reference ranges for native T1 time and ECV based on publications of at least 40 healthy subjects extracted from Table 60 are summarized in Table 61. The choice of pharmacologic stress agent is mostly determined by considerations of patient comfort, safety and cost. Typical CSF flow is 5-8 cm/s.
