Objectives To investigate the influence of kernels and iterative reconstructions on pericoronary adipose tissue (PCAT) attenuation in coronary CT angiography (CCTA). Materials and methods Twenty otherwise healthy subjects (16 females; median age 52 years) with atypical chest pain, low risk of corona...
