Role of advanced magnetic resonance imaging in the assessment of malignancies of the mediastinum

Figure 9 Treatment monitoring of an esophageal carcinoma by diffusion-weighted imaging. A 47 year-old male with esophageal carcinoma treated with esophagectomy and gastroplasty. A-D: Post-surgery surveillance magnetic resonance (MR) shows a normal appearing anastomosis on turbo spin echo (TSE) T2-weighted sequence and with no restriction on diffusion-weighted imaging and apparent diffusion coefficient (ADC) map (B-D; white arrows); D-G: Follow-up MR examination done 6 mo later revealing anastomotic thickening on TSE T2-weighted image and with restrictive behavior on diffusion-weighted whole-body imaging and ADC map (F-H), in keeping with relapse (blue arrows). ADC: Apparent diffusion coefficient.
