Weighted means were calculated based on the values of the diameter of the aortic root obtained on the 3D bSSFP sequence in LVOT view published by Burman, Davis and Le (Table 42) [11, 85, 86]. Peak of the mean systolic and diastolic velocities is in centimeters/second; these parameters were extracted from mean velocity-time curve as the area above the baseline represents the CSF diastole, the area below the baseline represents the CSF systole. Saturation recovery based techniques such as saturation recovery single-shot acquisition (SASHA) are alternative techniques but have less clinical evidence to date [105]. J Cardiovasc Magn Reson. Through-plane evaluation is performed in axial oblique plane perpendicular to the long axis of the aqueduct, and it is more accurate for quantitative analysis because the partial volume effects are minimized [4].

PWV was calculated as x/t, where x is defined as the length of the centerline between the sites of flow measurement in the ascending and descending aorta and t represents the time delay between the flow curve obtained in the descending aorta relative to the flow curve obtained in the ascending aorta (Fig. and Le Ven et al. Cardiac strain can be reported as three normal strains (circumferential, radial, and longitudinal) and six shear strainsthe angular change between two originally mutually orthogonal line elements, with the more clinically investigated shear strain and the circumferential-longitudinal shear strain (also known as torsion). In both studies included in this review, papillary muscles and trabeculations were included in the ventricular volumes and excluded from LV and RV mass. The flow plot demonstrates sinusoidal pattern of flow where negative values represent aqueductal systolic CSF volume (microliter) outflow and positive values represent diastolic CSF volume inflow.

Nevertheless, the clinical utility of CSF flow velocity analysis has remained limited, due to the wide variation of the CSF flow values observed in normal subjects (6, 16-18).

In normal adults, the CSF volume is 90 to 200 mL [ 1 ]; approximately 20 percent of the CSF is contained in the ventricles; the rest is contained in the subarachnoid space in the cranium and spinal cord. However, some FT-CMR reports showed no association of circumferential or longitudinal strains with age or gender [26, 177].
