The article addresses the diagnostic value of the combined use of computed tomography (CT) perfusion and dual-energy CT (DECT) in patients with neuroendocrine tumors. It emphasizes the heterogeneity and complexity of these neoplasms, primarily affecting the gastrointestinal tract, bronchopulmonary system, and pancreas. While conventional CT is widely employed in their diagnosis, the combination of CT perfusion and dual-energy CT offers greater precision, particularly in detecting synchronous tumors and characterizing their vascularization. A clinical case of a patient with chronic abdominal symptoms, whose diagnosis was facilitated using both combined techniques, is presented. The discussion explores how CT perfusion assesses tumor vascularization and how dual-energy CT improves soft tissue differentiation, resulting in increased diagnostic accuracy. It is highlighted that this approach not only enhances detection rates but also positively impacts clinical management and healthcare costs. Therefore, the importance of considering these advanced tools in the diagnosis of neuroendocrine tumors to improve diagnostic precision and efficiency in patient care is underscored.
本文探讨了计算机断层扫描（CT）灌注成像与双能CT（DECT）联合应用于神经内分泌肿瘤患者的诊断价值。文中强调了这些肿瘤的异质性和复杂性，主要累及胃肠道、支气管肺系统和胰腺。虽然传统CT在其诊断中广泛应用，但CT灌注成像与双能CT的联合应用能提供更高的精准度，尤其是在检测同步肿瘤及其血管特征方面。本文介绍了一名有慢性腹部症状患者的临床病例，其诊断借助了这两种联合技术。讨论探讨了CT灌注成像如何评估肿瘤血管生成，以及双能CT如何改善软组织分辨能力，从而提高诊断准确性。文中强调，这种方法不仅提高了检测率，还对临床管理和医疗成本产生了积极影响。因此，强调了在神经内分泌肿瘤诊断中考虑这些先进工具对于提高患者护理诊断精准度和效率的重要性。
