In placing the phased array coil, it is important to include the lower portion of the neck within the coil field-of-view if depiction of the arch vessels is desired. For some phased array coils (most Torso Array coils), the superior-to-inferior coverage is improved by rotating the coil90 0 so that the longer dimension of the coil is oriented superior-to-inferior and the shorter dimension is left-to-right. The morphology of the aorta can be complex. Congenital anomalies, aortic valvular disease, aneurysms and dissections, as well as generalized atherosclerotic disease, can alter its normal course.

Citing stent-related artifacts associated with various 2D spin echo and gradient echo sequences, MR imaging is generally not used for the assessment of stent patency. 17). 1 ms), the results were not as clear-cut as previously thought. Magnetic resonance artifacts associated with endoprostheses are related to both stent geometry and the underlying metal composing the stent. The effect of the latter dominated when imaging the stainless steel Palmaz stent or the cobalt-based alloy Easy Wallstent.

29 How Can Acquisition Time Be Shortened? The time to acquire a 3D volume of image data can be reduced by decreasing the TR. Depending upon the MR scanner, this may require purchasing high performance gradient systems. Beyond reduction in TR, there are several additional options for reducing the acquisition time. One is to use a wider bandwidth, although this causes areduction in signal-to-noise ratio. Another is to reduce the scan resolution or coverage. Finally, there are several k-space tricks that allow shortening acquisition time by reducing the number of phase encoding steps without sacrificing resolution.
