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.
