Background: Colon cancer is a common malignant tumor that often leads to intestinal obstruction, resulting in significant morbidity and mortality. Early and accurate diagnosis of colon cancer and associated ileus is crucial for timely treatment and improved patient outcomes. Various diagnostic methods, including MSCT and MRI, are currently used in clinical practice. However, the optimal imaging approach for accurate diagnosis remains uncertain.
Objective: To study the value and accuracy of multi-slice spiral CT (MSCT) combined with magnetic resonance imaging (MRI) in diagnosing colon cancer obstruction.
Methods: A retrospective analysis was performed on 100 cases of colon cancer and ileus patients admitted to the Hai'an Hospital of Chinese Medicine from January 2019 to July 2020. The cases were randomly divided into control and experimental groups, with 50 cases in each. The control group was diagnosed with MSCT, and the experimental group was diagnosed with MRI based on the control group. The positive and negative detection rates, test accuracy, sensitivity, and specificity were compared between the 2 groups. The area under the curve (AUC), quality of life (QOL) score, and mental status scale in non-psychiatric settings (MSSNS) score were calculated with the receiver operator characteristic curve (ROC) and compared between the 2 groups.
Results: The test accuracy, positive detection rate, negative detection rate, test specificity, sensitivity, and AUC of the experimental group were significantly higher than those of the control group, and the results were statistically significant (P < .05). There was no significant difference in the QOL and the MSSNS scores between the 2 groups (P > .05).
Conclusion: MSCT combined with MRI has a high application value in diagnosing colon cancer obstruction patients, and can significantly improve the test's accuracy, specificity and sensitivity.
