Abstract:
Objective:To study the detection rates of using different MRI sequences and enhanced CT in colorectal cancer liver metastasis (CRLM).Methods:The imaging data of CRLM patients who were treated at Peking University Third Hospital from March 2018 to September 2021 were retrospectively analyzed. Sixty-six CRLM lesions with a maximum diameter ≤10 mm were selected. Different MRI sequences such as T 1 weighted imaging (T 1WI), T 2 weighted imaging (T 2WI), diffusion weighted imaging (DWI), dynamic enhanced phase of MRI (MR-Dyn), gadolinium-etoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA), enhanced hepatobiliary phase of MRI (HBP) and CT enhancement phase (CT-Dyn) were reviewed independently to determine whether the target lesions were detected. The pathological results were used as the gold standard. Paired chi-square test was used to compare the detection rate of CRLM in each group. Results:Among the 66 liver metastases, 15, 31, 55, 21, 56 and 20 were detected by T 1WI, T 2WI, DWI, MR-Dyn, HBP and CT-Dyn, respectively. Their detection rates were 22.7%, 47.0%, 83.3%, 31.8%, 84.8% and 30.3%, respectively. The detection rates of HBP and DWI were higher than those of T 2WI, MR-Dyn, CT-Dyn and T 1WI, respectively (all P<0.05). The detection rate of T 2WI was higher than that of MR-Dyn, CT-Dyn and T 1WI (all P<0.05). The detection efficiencies of non-contrast MRI and Gd-EOB-DTPA enhanced MRI for CRLM were highly consistent ( Kappa=0.745). Conclusions:The detection rates of HBP, DWI and T 2WI for CRLM were high. Non-contrast MRI could replace Gd-EOB-DTPA enhanced MRI for detection of large CRLM.
