BMC: Post-TIA ultrasounds identify risk for future cardiac event

Clinical Studies | Thursday, July 30 2009
Ultrasound can be used to determine a patient's cardaic event risk after a transient ischemic attack (TIA). An evaluation of transcranial and extracranial Doppler ultrasonography, published July 30 in BMC Medical Imaging, demonstrated that both future stroke and future cardiovascular ischemic events can be predicted by abnormal findings.
 

SCCT Feature: Poll reveals changes in perceived cardiac CT appropriateness

Top Stories | Wednesday, July 22 2009
Since the Appropriateness Criteria for cardiac CT (CCT) was published in 2006, the modality has experienced rapid growth in technology and clinical use. When the American College of Cardiology (ACC) formally reviews the criteria next year, there might be room to add more indications to the "appropriate" category, including the "triple rule-out" exam, according to a study presented at the Society of Cardiovascular Computed Tomography (SCCT) meeting in Orlando, Fla., last week.
