Fig. 6.1 Slice positioning on the vertical long-axis (VLA) (a) and 4-chamber (4CH) (b) planes to obtain multislice short axis (SAX) images (c) from base to apex of the ventricles….

Fig. 23.1 Plain abdominal film showing kink of the left iliac limb of an aorto-biiliac EVAR 2 Ultrasound Ultrasound is a noninvasive method that does not use ionizing radiation. It…

Fig. 3.1 Sixty-one-year-old female with carotid stenosis. In TOF images proton dephasation occurs at the site of stenosis causing intraluminal loss of signal simulating focal occlusion. Contrast-enhanced images demonstrate lumen…

Fig. 9.1 Sequential imaging of bilateral carotid artery stenosis. TOF depicts the area of luminal narrowing. Axial slices depict the full extent of the atherosclerotic process, including expansive remodeling. The…

Fig. 7.1 A typical histological section of a vulnerable carotid plaque It has been accepted that both plaque morphology and biomechanical environment of the plaques influence their vulnerability [57]. The…

Fig. 1.1 (a) Ultrasonographic morphology of the normal arterial wall with quantification of the intima–media thickness (IMT). (b) Increased IMT with destruction of the normal artery morphology Fig. 1.2 Progression…

where c is the concentration of GBCM. The observed relaxivities R1,2 can be thought of as the sum of an intrinsic relaxivity (i.e., the true tissue T1 and T2) and…

Fig. 10.1 Measuring the degree of luminal narrowing using the NASCET method involves measuring the minimal residual lumen diameter at the level of maximal stenosis (double arrow), measuring the lumen…
