| 目的 观察能谱CT 物质分离技术用于诊断四肢外伤性骨髓水肿的价值。方法 回顾性收集51例四肢外伤性骨髓水肿患者,根据年龄分为青壮年组(n=26,18~43岁)及中老年组(n=25,46~74岁)。以MRI为参考标准,分析能谱CT水(Water)-羟基磷灰石(HAP)图判断外伤区域是否存在骨髓水肿的效能,并比较2组Water-HAP密度值。结果 能谱CT与MRI诊断骨髓水肿差异无统计学意义(χ2=0.201,P=0.654)且一致性较高(Kappa值=0.774)。骨髓水肿区域Water-HAP密度值高于非骨髓水肿区域(t=24.634,P＜0.05),2组骨髓水肿区域及非骨髓水肿区域Water-HAP密度值差异均无统计学意义(P均＞0.05)。结论 能谱CT物质分离技术有助于诊断四肢外伤性骨髓水肿。 |

| Objective To observe the value of spectral CT material separation technology for diagnosing traumatic bone marrow edema in limbs. Methods Totally 51 patients with limb traumatic bone marrow edema were retrospectively enrolled and divided into young group (n=26, 18—43 years)and middle-aged group (n=25, 46—74 years). Taken MRI as reference standard, the efficacy of spectral CT Water-hydroxyapatite (HAP) image for diagnosing bone marrow edema in trauma area was analyzed,and the Water-HAP density values were compared between groups. Results No significant difference of diagnosing bone marrow edema was found between spectral CT and MRI (χ2=0.201, P=0.654), and the consistency was high (Kappa=0.774). Water-HAP density value in bone marrow edema area was higher than that in non bone marrow edema area (t=24.634, P＜0.05), and no significant difference of Water-HAP density values in bone marrow edema area nor non bone marrow edema area was found between young group and middle-aged group (both P＞0.05). Conclusion Spectral CT material separation technology was helpful for diagnosing traumatic bone marrow edema in limbs. |
