Pancreatic hardness: Correlation of surgeon’s palpation, durometer measurement and preoperative magnetic resonance imaging features

Table 2 Comparison of parameters between two groups based on the surgeon’s subjective analysis of the pancreas

	Soft (n = 44)	Hard (n = 39)	P value
Parenchyma diameter	15 (13-20.75)	15 (13-20)	0.791
Duct diameter	3 (1-3)	5 (3-7)	< 0.001
D/P ratio	0.13 (0.08-0.23)	0.25 (0.18-0.55)	< 0.001
ADCmean (mm2/s)	1.62 (1.50-1.77)	1.45 (1.24-1.63)	0.012
ADCmin (mm2/s)	1.51 (1.32-1.59)	1.27 (1.11-1.47)	0.004
RSID (%)	10.2 (5.9-22.5)	15.2 (7.8-22.8)	0.174

Data are presented as the median and interquartile range. D/P ratio: Duct/parenchyma ratio; ADC: Apparent diffusion coefficient; ADC_mean: Mean ADC value; ADC_min: Minimal ADC value; RSID: Relative signal intensity decreases.
