B-mode ultrasonographic (US) angiography enhanced with a microbubble-based US contrast agent (FS069) was evaluated in human subjects with carotid artery disease. Results at contrast material-enhanced US angiography and duplex US were compared with those at conventional angiography. Both US angiography and duplex US accurately depicted stenoses of 70% or more compared with those depicted at conventional angiography. The percentage diameter stenosis of the internal carotid artery measured at US angiography strongly correlated with that measured at conventional angiography (r = 0.988). The percentage area stenosis measured at US angiography strongly correlated with ex vivo measurements of the resected carotid plaque at magnetic resonance imaging (r = 0.979). US angiography depicted unsuspected wall irregularities, ulceration, and dissection.
Percutaneous vertebroplasty has now been in use in the United States for 10 years. Standards of practice are available from the American College of Radiology. The performance of this procedure is becoming routine for most interventional practices, and it has become the general standard of care for pain associated with vertebral compression fractures of the spine. This article describes routine procedural technique and considerations and is intended to review the authors' knowledge of the procedure and provide reliable methods for good outcomes and complication avoidance.
