Abstract:
PurposeTo explore the value of gemstone spectral imaging (GSI) in diagnosis of thyroid nodule hemorrhage.Materials and Methods Seventeen patients with surgery and pathology confirmed thyroid nodule hemorrhage underwent thyroid spectrum CT scan. The CT value, iodine concentration value, water concentration value and the effective atomic ordinal value as well as spectral curve slope of hemorrhagic nodules and surrounding normal thyroid tissue were measured respectively.Results Hemorrhagic thyroid nodules showed equal or high CT value, low concentration of iodine, high concentration of water, low spectral curve slope, and low effective atomic ordinal value on spectral CT imaging. There were statistically significant differences in concentration of iodine value, concentration of water value, and spectral curve slope between hemorrhagic nodules and surrounding normal thyroid tissue (Z=-5.438,-4.679 and-5.317,P<0.01), and there were statistically significant differences in CT value and effective atomic ordinal value (Z=-2.097 and-2.230,P<0.05).Conclusion Energy spectrum CT scan is important in detection and accurate diagnosis of thyroid nodule hemorrhage.
