The invention provides for a magnetic resonance imaging system (100) that comprises a sensor system (122) for measuring subject data (156) and a user interface (132). Machine executable instructions (140) causes a processor (134) to receive (200) a set of examination commands (142) and initiate (202) execution of them. Before executing each magnetic resonance imaging protocol of the set of examination commands, the processor repeatedly: receives (204) the subject data； determines (206) an examination status (154) using the set of examination commands； calculates (208) at least one scan decision probability (160) using a machine learning algorithm (158) by inputting the subject data and the examination status； pauses (212) execution of the set of examination commands if the at least one scan decision probability is within one or more predetermined probability ranges (162)； displays (214) a user prompt (164, 164', 164") on the user interface if the at least one scan decision probability is within the one or more predetermined probability ranges； receives (216) the modification instructions from the user interface； modifies (218) the set of examination commands； and resumes (219) execution of the set of examination commands.
