| Core Tip |
This study evaluated the value of high-resolution magnetic resonance imaging combined with dynamic contrast-enhanced scanning for preoperative staging of rectal cancer in older patients. In a retrospective analysis of 148 patients (December 2020 to December 2024), postoperative histopathology served as the gold standard. T staging accuracy was 84.5%, with a sensitivity of 62.5%-90.5% and specificity of 79.3%-100% across T1-T4 stages, demonstrating excellent agreement with pathological staging (k = 0.817, P < 0.001). Conversely, N staging showed lower sensitivity (36.96%-70.0%) and specificity (72.55%-84.85%), with poor agreement (k = 0.259, P < 0.001). Overall, this combined imaging approach provides high diagnostic accuracy for T staging to guide treatment planning, although its performance in N staging requires improvement. |
