Figures
- fig 1.
A, Composite extended-FOV image in a patient with cervical spondylosis shows a partially hyperechoic plaque at the ICA (straight arrow). Note mild hyperplasia of the intima at the CCA and bifurcation (curved arrows).
B, Extended-FOV image with a selected original frame provides a more precise picture of the CCA. Intimal hyperplasia was detected (left, arrow). The dotted square on the extended-FOV image (right) represents the position of the original frame displayed on the left.
C, Selected original frame of the ICA shows a hyperechoic plaque (left, arrow).
- fig 2.
Extended-FOV sonogram shows atheromatous plaque at the carotid bifurcation that extended to the proximal ICA (straight arrows). The lumen was narrowed but the stenosis was less than 40%. Another small plaque was detected in the CCA (curved arrow). The normal double-line pattern was obscured at these sites of disease, and there was diffuse intimal hyperplasia at the CCA.
- fig 3.
A, Extended-FOV image with unacceptable image distortion due to large-scale patient motion. Irregular deformity and discontinuity of the arterial wall make precise evaluation of the wall structure difficult (arrow). The FOV is not satisfactorily extended.
B, Extended-FOV image with mild distortion due to arterial pulsation (right). A regular waveform deformity is present on the wall of the CCA (right, straight arrow). There is also a discontinuity of the artery due to improper probe operation (right, curved arrow). The original frame is free from the motion artifact and shows the normal double-line pattern of the artery (left).
