We study the problem of the boundedness and compactness of 𝑇 𝜙 when 𝜙 𝐿 2 ( Ω ) and Ω is a planar domain. We find a necessary and sufficient condition while imposing a condition that generalizes the notion of radial symbol on the disk. We also analyze the relationship between the boundary behavior of the Berezin transform and the compactness of 𝑇 𝜙 .
