| We devised a new method of Mobi-track MRA by applying the conventional CP body array coil and our own sliding table. This method was applied for MR angiography of lower leg arteries combined with a subtraction technique. The performance of our method, which uses the CP body array coil, was examined in regard to misregistration of difference images, signal-to-noise ratio, contrast-to-noise ratio, and signal detectability, for comparison with that of the method using the body coil. Experimental results showed that our new method was superior to the method using the body coil. In conclusion, we consider our new method, which employs the CP body array coil and sliding table, to be very useful for three-dimensional MR angiography of lower leg arteries. |
