Pelvic MRI findings before and after pCRT in the high-resolution T2w sequences using a 3.0 Tesla Siemens Prisma MRI Scanner (Siemens Healthineers AG, Erlangen, Germany) with a contrast of Gadobutrol Injection (Gadovist). A Pelvic MRI before pCRT showing rectal tumor and left enlarged lateral LNs (axial T2WI sequence, no fat suppression, oblique transverse section, TR 2000, TE 95, FOV 20×20); B Pelvic MRI before pCRT showing left enlarged inguinal LNs (axial T2WI sequence, no fat suppression, oblique transverse section,TR 2000, TE 95, FOV 20×20); C After pCRT the rectal tumor and left enlarged lateral LNs decreased in size (axial T2WI sequence, no fat suppression, oblique transverse section, TR 2000, TE 89, FOV 22×22); D After pCRT the left enlarged inguinal LNs decreased in size (axial T2WI sequence, no fat suppression, oblique transverse section, TR 2000, TE 89, FOV 22×22). MRI: magnetic resonance imaging; LNs: lymph nodes; pCRT: preoperative chemoradiotherapy; T2WI: T2 weighted imaging; TR: repetition time; ET: echo time; FOV: field of view
