What are the four comparison modalities used for QA correlations?

• A. Angiography, Nuclear, Cath, Surgical Pathology
• B. Echocardiography, Nuclear, Cath, Surgical Pathology
• C. Angiography, Nuclear, Echocardiography, MRI
• D. Angiography, Nuclear, Cath, Ultrasound

Answer: (A)

In quality assurance correlations, you want to compare findings across tools that capture different aspects of disease: anatomy, function, invasive measurements, and tissue confirmation. Angiography shows the actual lumen and vessel anatomy, giving a clear view of structural relationships. Nuclear imaging adds functional or perfusion information, helping to assess how well blood flow and tissue metabolism match the anatomy seen on angiography. Cardiac catheterization provides direct invasive hemodynamic data and precise assessment of lesions, giving a gold standard for physiologic impact. Surgical pathology offers definitive tissue diagnosis when available, allowing histologic confirmation of disease. Together, these modalities cover structural, functional, and histologic references, enabling robust QA correlations. Other options may substitute modalities that, while important, don’t provide the same comprehensive cross-check with a definitive tissue diagnosis. This combination is especially useful in QA contexts where multiple dimensions of disease need to be validated against each other.
