Comparison of photon-counting CT angiography with energy-integrating CT angiography in coronary artery stenosis: a systematic review and meta-analysis.

ABSTRACT:

Purpose

To perform CT-angiography of coronary arteries, energy-integrating detector computed tomography (EID-CT) is widely used but it has several limitations, especially in overestimation of size of calcium plaques. Photon-counting detector computed tomography (PCD-CT) promises better image quality and lower radiation. This study compares the efficacy, radiation dose, and image quality of EID-CT and PCD-CT for coronary artery disease (CAD) diagnosis.

Materials and methods

A systematic review and meta-analysis were conducted per PRISMA guidelines. Four databases were searched for studies directly comparing EID-CT and PCD-CT. Data on coronary artery calcium scores (CACS), radiation dose index (mGy), dose-length product (DLP), and image quality were extracted. Risk of bias was
