Abstract

Aim: This study aimed to clarify the ultrasound semiotics of colorectal cancer liver metastases contrast enhancement, and perform a comparative assessment of the diagnostic efficacy of contrast-enhanced ultrasound and computed tomography (CT).Methods: We studied 40 patients with colorectal cancer: patients receiving treatment for the disease and having newly diagnosed colorectal cancer. All patients underwent contrast-enhanced ultrasound and CT. In the cases of suspected malignancy, a trephine biopsy and a morphological examination were performed.Results: Contrast-enhanced ultrasound and CT demonstrated comparable and high diagnostic efficacy. The sensitivity of the contrast-enhanced ultrasound in malignancy detection was 93.3%, with 90% specificity, 96.55% positive predictive value, 81.82% negative predictive value, and 92.5% accuracy. The sensitivity of contrast-enhanced CT was 93.3%, with 80% specificity, 93.33% positive predictive value, 80% negative predictive value, and 92.5% accuracy.Conclusions: For patients with colorectal cancer with contraindications to contrast-enhanced CT, contrast-enhanced ultrasound may be used an alternative imaging option for the differential diagnosis of liver neoplasms.
计算机断层扫描与超声造影对结直肠癌癌症肝转移诊断价值的比较评价
目的:本研究旨在明确结直肠癌肝转移瘤的超声符号学,并对超声增强与CT的诊断效果进行比较评估。方法:对40例结直肠癌患者进行研究,包括正在接受治疗的结直肠癌患者和新诊断的结直肠癌患者。所有患者均行超声增强和CT检查。在疑似恶性肿瘤的情况下,进行了穿刺活检和形态学检查。结果:超声与CT的诊断效果相当,具有较高的诊断效率。超声造影检测恶性肿瘤的敏感性为93.3%,特异度为90%,阳性预测值为96.55%,阴性预测值为81.82%,准确率为92.5%。CT增强检查敏感性93.3%,特异度80%,阳性预测值93.33%,阴性预测值80%,准确率92.5%。结论:对于有CT造影禁忌症的结直肠癌患者,超声造影可作为肝脏肿瘤鉴别诊断的替代影像学选择。
