Abstract EN
Aim.
This study is aimed at comparing gastric cancer T and N staging between virtual monochromatic energy images and fusion images generated by dual-source computed tomography (DSCT) dual-energy mode data acquisition prospectively while measuring the iodine concentration of gastric cancer and lymph nodes at different T and N stages from iodine map retrospectively.
Methods.
A total of 71 patients (50 males and 21 females; mean age: 59 ± 11 years) confirmed with gastric cancer by endoscopic biopsy with no neoadjuvant chemotherapy were enrolled for the CT examination before surgeries.
The preoperative T and N staging results were compared between groups with pathological results as the gold standard.
The iodine concentrations of the gastric lesions and LNs were measured on the iodine-based material decomposition images.
All iodine concentration values were normalized against those in the abdominal aorta and defined as normalized iodine concentration (nIC) values.
The short axis length of LNs and nIC values were statistically analyzed.
Results.
Group A was better than group B for T3 and T4 staging.
No statistically significant difference in the overall accuracies for N staging was found between groups.
For the late arterial and delayed phases, T3 and T4 nIC values of the extraserosal adipose tissue showed statistically significant differences.
The nIC values between N0 and Nm (N1–N3) showed statistically significant differences in the portal phase only.
Conclusions.
T3 and T4 nIC values of the extraserosal adipose tissue showed statistically significant differences.
Hence, dual-source CT may be helpful in the differential diagnosis between T3 and T4.
