Fig. 1From: Arterial spin labeling and diffusion-weighted imaging for identification of retropharyngeal lymph nodes in patients with nasopharyngeal carcinomaBox-plots of comparisons between three groups. Error bar plots showed the difference of short axis (a), long axis (b), mean BF (c), and ADC (d) values of RLNs with LNM (metastatic RLNs from NPC patients), non-LNM1 (non-metastatic RLNs from NPC patients), and non-LNM2 (non-metastatic RLNs from healthy control participants)Back to article page
