64-slice CTA tops SPECT in coronary disease patients
Sixty-four-slice CT angiography could become the imaging study of choice to rule out cardiac catheterization in patients with an intermediate risk of coronary artery disease.
Sixty-four-slice CT angiography could become the imaging study of choice to rule out cardiac catheterization in patients with an intermediate risk of coronary artery disease.
Dr. Tamar Gaspar and colleagues at Carmel Medical Center in Haifa, Israel, reviewed retrospective data from 75 symptomatic patients who underwent 64-slice CTA and SPECT. They reported at the 2006 RSNA meeting that CTA identified significant stenosis in one-third of patients and excluded it in two-thirds of patients who showed grade 1 mild reversible perfusion defects on SPECT.
"If we can show normal coronaries on CT and take into account the high negative predictive value of CT for CAD, we won't have to refer these patients for invasive angiography," Gaspar said.
