The reviewed literature shows marked inter-country variation in DRL methodology, updating cycles, and regulatory integration. In Jordan, available studies demonstrate useful local and multicenter data, but routine CT practice still lacks a unified national DRL framework. Reported Jordanian values also show inter-institutional variability, highlighting the need for standardized data collection, regular auditing, and coordinated national oversight.
