Table 2: Image scoring system for visual grading analysis of DW MR images.

Score Image Quality Descriptor Criteria for grading
1 Not acceptable Definite loss of information, image not diagnostically usable.
2 Acceptable Moderate limitations of artefacts, no substantial loss of information, images not optimal, but diagnostically acceptable.
3 Optimal No artefact related limitations, no loss of information, images optimal for diagnostic purposes.
