The present research was done aiming to determine the influence source of out on the output and affective of hospitals Radiology Unit. Finding obtained to that the weight media of patients’ satisfaction score in turn over radiology units was (41.46) and in non-turned over was (45), being significant from the difference statistical point of view. Results indicated that the patients’ consent was higher with non-turned over radiology units and therefore the outsourcing had no positive affect on the patients’ satisfaction which was similar to studies of Baderaldin, Amerion and Mohaghegh and in contrast with primarily expectancy of executing outsourcing procedure. The most extended rate of discontent between patients in analyzing the major factors of discontent was the long time duration of waiting . Amerion considered the lack of sufficient explanation in order to get ready for radiology the reason for the minimum rate of satisfaction (7.8%) , while Mohaghegh et al. presented the insufficient time investment of pharmacy employees for consulting  as being a reason. Meanwhile, the present research daresay that loss consent in turned over unit was the conclusion of giving the turn system the minimum median of (3.11) and, to confirm this, we could mention the lack of devoting enough work force for recipient part in turned over unit, existence of 5 secretaries in 3 working shifts for the whole unit, which included radiology, MRI, bone accumulation and another aims, led to the increment in work load, and, as a finding, caused problems in the system of giving turns.
