Fig. 4.1 Sequential images of the opening and closing cycle of the jugular and vertebral valve system (from a to e) as dynamically shown also in Movie 4.1. First of all,…

Fig. 7.1 Contrast-enhanced brain CT of a young patient with cerebral vein thrombosis, involving the left TS, the confluens of sinuses, and the distal end of the SSS. In the picture…

Fig. 6.1 Power-mode TCCS from temporal window in axial scanning plane (mesencephalic plane). The ipsilateral basal vein of Rosenthal is sampled in the pre-peduncular segment, with flow direction toward the probe…

Fig. 2.1 Schematic drawing of IJV and its segments. (1) J1 or proximal segment, focused to the valve system. (2) J2 or intermediate segment. (3) J3 or distal segment, where the…

Fig. 3.1 J2 IJV segment in transverse scanning plane. Sometimes there is a huge variation between IJV expiratory CSA (figure above) and inspiratory CSA (figure below) during normal breath. See the…

Fig. 8.1 Example of cerebral venous outflow measurement in supine position on the right side. a J3 IJV Doppler sampling and TAV measurement. b J3 IJV CSA measurement and automatic blood…

Fig. 1.1 IJV in longitudinal scanning plane. The B-mode has no steering, and the color box has a variable degree and direction of steering. Therefore, there is a different visualization of…

Fig. 5.1 a–c The picture shows an example of the effect of decreasing PRF in the ultrasound preset for venous study in power mode. TCCS from the temporal bone window in…
