Figure 4a: Box plots show (a) median, interquartile range, and extreme cases of absolute ADC values; (b) SI ratio on DW images; and (c) SI ratio on T2-weighted images in three groups of macroadenomas according to consistency. Significant associations between tumor consistency and ADC values, SI ratio on DW images, and SI ratio on T2-weighted images were observed (P < .05, analysis of variance). A horizontal reference line is drawn at ADC value of 1 mm2/sec, which could be used as a cutoff value to differentiate tumors amenable to aspiration, because of small overlap between ADC values of tumors in the hard versus the soft or intermediate group. ADC values are expressed in squared millimeters per second.
