Diagnostic performance of PET, SPECT and CMR perfusion imaging for the detection of significant coronary artery disease - a meta-analysis
Journal of Cardiovascular Magnetic Resonance volume 13, Article number: P75 (2011)
Non-invasive myocardial perfusion imaging for the detection of significant coronary artery disease (CAD) has advanced rapidly. Consensus on the best imaging modality has not been reached as few studies compare them directly.
To determine and compare the diagnostic accuracy of positron emission tomography (PET), single-photon emission computed tomography (SPECT) and cardiac magnetic resonance (CMR) perfusion imaging in the diagnosis of CAD.
Studies published in the English language between January 1980/1990 (for PET / SPECT and MRI respectively) and February 2010 identified by PubMed search and citation tracking were examined.
A study was included if PET, SPECT or CMR perfusion imaging was used as a diagnostic test for the detection of CAD (≥50% diameter stenosis) and used coronary angiography as the reference standard.
Four reviewers screened potential studies and independently extracted study data. Discrepancies were resolved by consensus.
Of the 3694 citations, 166 articles (17.744 patients) met the inclusion criteria: 18 PET (1.441 patients), 111 SPECT (13.462 patients) and 37 CMR (2.841 patients) articles respectively. The overall patient based analysis demonstrated a sensitivity of 0.85 (95% confidence interval [CI] 0.83-0.88), 0.88 (95% 0.88-0.89) and 0.89 (95% CI 0.88-0.91); and a specificity of 0.83 (95% CI 0.76-0.88), 0.60 (95% CI 0.59-0.62), 0.76 (95% CI 0.73-0.78) for PET, SPECT and MRI respectively.
Non-invasive PET, SPECT or CMR perfusion imaging are accurate modalities for the detection of CAD. Of the three different imaging modalities PET has the best diagnostic performance. However, the number of publications on PET perfusion imaging is limited and the prevalence of CAD in PET study populations was higher. In addition, this technique is hampered in daily practice by availability and costs. CMR provides an excellent alternative without ionizing radiation exposure and a similar diagnostic accuracy.
