Bolus chasing), acquiring images longitudinally. ” “Knee-arrival time” is computed by fluoroscopically observing a small test bolus of contrast arrive at the popliteal artery prior to the full injection; then it is used by the system’s microprocessor to optimize the contrast 22 S. I. Wahl and K. M. Zinn injection rate and volume and to coordinate it with an appropriate acquisition sequence. Opacification of extremities can be enhanced, if necessary, by inducing reactive hyperemia after the release of pressure cuffs from the calves, warming the extremity, or using vasodilators such as intraarterial nitroglycerin, tolazoline, or papaverine.
Also, the fluoroscopic image remains on the monitor and can be magnified without requiring additional fluoroscopy. Postprocessing adjustments always can be made to improve image quality. One new equipment option allows active rotation of the C-arm (up to 20 to 30 degrees/second) during contrast injection; this technique can obtain multiple projections during a single contrast run. With all the advantages offered by DSA, only a few disadvantages are encountered. These stem primarily from sequential pixel malalignment resulting from patient, cardiac, respiratory, and bowel motion.
Filming near the contrast injection site generally mandates faster rates than filming downstream at a distance from the catheter. The goal is to maximize the diagnostic information obtained during each contrast injection without excessive contrast dose or exposure to the patient and without a waste of x-ray film or radiation. Film or acquisition sequences Filming sequences are stated as the number of films exposed per second for a specified duration of seconds. The 17 18 A S. I. Wahl and K. M. Zinn B FIGURE 3-1.
