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

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.
