Abstract:
Objective To analyze the value of conventional T2WI combining with breath-hold Cartesian VIBE sequence, and compared with Blade combining with breath-free radial VIBE sequences in pre-operative T staging of potentiallly resectable esophageal carcinoma. Methods Sixty-five cases of esophageal carcinoma were concluded prospectively. All patients had received pathological examination of gastroscope biopsy before MRI. Patients received MR examination, including T2WI, breath-hold VIBE, Blade, and breath-free radial VIBE sequences. Two radiologists with more than five years experiences in the diagnosis of chest, performed T staging in MRIby referring to the the 7th edition of UICC-AJCC TNM classification. The results of MRI T staging and the postoperative pathological T staging were analyzed byχ2 test. Results Sixty-five patients were included. Diagnostic coincidence rates of the preoperative T staging by using conventional T2WI combining with breath-hold Cartesian VIBE sequences and Blade combining with breath-free radial VIBE sequences were 51%(33/65) and 88%(57/65) ,with 32 and 8 cases overstaging or understaging respectively, and the statistical differences were significant(χ2=20.80, P<0.05). The former diagnostic accuracy of esophageal carcinoma in situ, muscularis violation and esophageal fiber membrane were 42%(8/19), 54%(14/26), 55%(11/20), and the latter were 89%(17/19), 88%(23/26), and 85%(17/20). Conclusions Diagnostic coincidence rate of the preoperative T staging by using Blade combining with breath-free radial VIBE sequences is much higher than conventional T2WI combining with breath-hold Cartesian VIBE sequences. Blade combining with breath-free radial VIBE sequences could be used as non-invasive imaging method in preoperative T staging of potentially resectable esophageal carcinoma.
