researcher defined the gradients in line 10 of the last page. It could have been better if it was placed in the Introduction rather than in the last page since definitions were intended to introduce the reader to the significant terms used in the writing.
The researcher wrote in the second paragraph of the abstract, “Human research magnets of 7T and 8T are operation in several site worldwide.” However, it is quite disturbing why these types of magnets were mentioned in the abstract but nothing in the research paper discussed these things. Said sentence therefore appears to be irrelevant. Thus, the researcher must either discuss these types of magnets in the body of the paper or better yet, totally delete the above-quoted sentence.
In addition, the author mentioned in the introduction that he/she will elaborate on the different gradient types and designs thereof. However, perusal of the body of the research paper would show that only the three (3) main ingredients, to wit, z, y and x, were discussed as part of the MR system.
In the last paragraph of the summary, the author stated, “the distinct advantages over normal radiographs and CT examinations, is that it does without the delivery of ionizing radiation to the patient”. I respect the author’s view; however, I cannot agree on this as MRI gives precise contrast differences between soft tissues that significantly help in diagnosing abnormalities than other normal radiographs and CT examinations.
