New scoring system in assessment of Hoffa’s fat pad synovitis: A comparative study with established scoring systems

Table 4 Correlation with the parapatellar synovitis score

		1.5T	3T	Total
Thickness	T1CE	0.63	0.73	0.70
	PD	0.52	0.45	0.47
	PD-FS	0.44	0.51	0.49
SM score	T1CE	0.85	0.79	0.81
	PD	0.42	0.76	0.66
	PD-FS	0.79	0.59	0.65
MOAKS	T1CE	0.66	0.56	0.59
	PD-FS	0.65	0.52	0.56
WORMS (effusion synovitis)	PD-FS	0.64	0.81	0.76
Effusion-diameter	PD-FS	0.52	0.62	0.59

All P values are less than 0.01. T1CE: T1-weighted fat-suppressed fast spin-echo sequence; PD: Proton density-weighted fast spin-echo sequence; PD-FS: Proton density-weighted fat-suppressed fast spin-echo sequence.
