Free-breathing radial volumetric interpolated breath-hold examination vs breath-hold cartesian volumetric interpolated breath-hold examination magnetic resonance imaging of the liver at 1.5T

Table 1 Image quality parameters and scoring criteria

Image qualityparameter	Scoring criteria
Liver edge sharpness	1 Non diagnostic; severe blurring
	2 Poor and unacceptable; moderate to severe blurring resulting in considerable loss of anatomic detail
	3 Fair and acceptable; mild blurring resulting in acceptable images with minimal loss of anatomic detail
	4 Good and diagnostic; barely perceptible blurring
	5 Very good and sharp
Artifacts	1 Non-diagnostic; severe artifacts
	2 Poor and unacceptable; moderate to severe artifacts resulting in significant loss of information
	3 Fair and acceptable; mild artifacts and very minimal loss of information
	4 Good and diagnostic; no perceptible artifacts in the area of interest and minimal artifacts at the margins
	5 Very good; no artifacts
Hepatic vessel clarity	1 Uninterpretable
	2 Severely blurred
	3 Moderately blurred
	4 Mildly blurred
	5 Sharp
Lesion conspicuity	1 Most lesions not seen
	2 Most lesions barely seen but margins and internal heterogeneity not well delineated
	3 All lesions seen with at least 50% of the lesions showing good delineation of margins and internal heterogeneity
	4 All lesions seen with at least 75% of lesions showing good delineation of the margins and internal heterogeneity
	5 All lesions seen with good delineation of margins and internal heterogeneity
Fat saturation	1 Unacceptable
	2 Poor
	3 Fair
	4 Good
	5 Very good
Overall image quality	1 Non-diagnostic
	2 Poor and unacceptable
	3 Fair and acceptable
	4 Good and diagnostic
	5 Very good
