Core Tip

Core Tip: To improve the diagnostic accuracy of metastatic lymph node detection in colorectal cancer (CRC), this study emphasizes the potential of gemstone spectral computed tomography imaging as a promising solution. Systematic assessment confirms that gemstone spectral computed tomography imaging demonstrates high diagnostic efficacy in detecting lymph node metastasis in patients with CRC. Among the spectral parameters analyzed across arterial and venous phases, iodine concentration in the arterial phase demonstrates the greatest diagnostic performance. These results provide novel clinical information, supporting optimized surgical decision-making and improved monitoring strategies for patients with CRC with lymph node metastasis.
