1. A medical imaging device comprising: a magnetic resonance imaging system for acquiring magnetic resonance data; a processor for controlling the medical imaging device; a memory containing machine executable instructions for execution by the processor, wherein execution of the instructions controls the processor to: receive an initial pulse sequence protocol, wherein the initial pulse sequence protocol comprises device protocol parameters and instructions which control the magnetic resonance imaging system to acquire the magnetic resonance data; determine an initial pulse sequence classification of the initial pulse sequence protocol; receive modifications to the initial pulse sequence protocol; modify the initial pulse sequence protocol with the received modifications to determine a modified pulse sequence protocol; determine a modified pulse sequence classification of the modified pulse sequence protocol; determine a magnetic resonance contrast classification based on the modified pulse sequence classification; determine a modified pulse sequence protocol classification based on the modified pulse sequence classification and the determined magnetic resonance contrast classification; determine corrective modifications to the modified pulse sequence protocol when the modified pulse sequence protocol classification is changed from the initial pulse sequence protocol classification to the modified pulse sequence classification, wherein the determined corrective modifications identify further modifications to the modified pulse sequence protocol which will return the modified pulse sequence protocol classification to the initial pulse sequence protocol classification; and control a display to display a correction message on the display, wherein the correction message is descriptive of the determined corrective modifications.
