- W2090989690 abstract "New tests, such as magnetic resonance imaging (MRI) and electron-beam computed tomography (CT), are being developed for the diagnosis of coronary artery disease.To determine the conditions that a new test must meet to be a cost-effective alternative to established imaging tests.Decision model and cost-effectiveness analysis.Literature review and meta-analysis.55-year-old men and 65-year-old women presenting with chest pain.Lifetime of the patient.Health care policy.MRI, electron-beam CT, exercise echocardiography, exercise single-photon emission CT, and coronary angiography.Target sensitivity and specificity values for a new noninvasive test.Assuming that society is willing to pay $75000 per quality-adjusted life-year (QALY) gained, a new test that costs $1000 would need a sensitivity of 94% and a specificity of 90% to be cost-effective.Assuming that society is willing to pay $50000 per QALY gained, a new test that costs $1000 or more would never be cost-effective. For a test that costs $500, the sensitivity and specificity must each be 95%.New imaging techniques, such as MRI and electron-beam CT, must be relatively inexpensive and have excellent sensitivity and specificity to be cost-effective compared with other techniques for the diagnosis of coronary artery disease. Similar analyses in other areas of health care may help to focus the development of new diagnostic technology." @default.
