MDCT offers cost-effective, reliable diagnosis in low-risk angina patients
By Eric Barnes
As many as 6 million patients with chest pain are admitted to emergency departments every year in the U.S. Coronary CT angiography (CTA), despite real limitations, has been shown to diagnose some patients quickly and accurately. In a new study, 64-slice CTA provided the correct diagnosis in 95% of patients with low-risk acute chest pain, leading the authors to conclude that CTA was well suited to diagnosing this population. Still, a quarter of the patients needed additional examination to determine that CT had been correct all along.
