摘要
背景:11C-甲硫氨酸-PET(MET)和氯化铊-201-SPECT(TL)可用于预测胶质瘤患者的增殖能力和确定肿瘤侵犯范围,但在任何医院或国家都不一定能实现。我们的研究旨在评估是否能从多形性胶质母细胞瘤(GBM)患者钆(Gd)-T1加权磁共振成像(Gd-MRI)的对比增强病灶中预测MET和Tl的累积范围:在 25 个病例中,在与钆增强最大面积(Gd-Area)相同的轴截面上测量 MET-Area、TL-Area、MET 和 TL 重叠的 O-Area 以及所有积聚区(AA-Area)。对所有轴向融合切片重复这一追踪操作,并测量每个容积(Gd-V、MET-V、TL-V、O-V、AA-V):结果:MET 和 TL 在 Gd-Area 外的最大累积距离分别限制在 30 毫米和 35 毫米以内。所有组合都与 Gd-Area 呈显著正相关:MET-Area(r=0.851,p结论:肿瘤的近似体积 Gd-V 可用公式 A * B * C / 2 计算,其中 A、B 和 C 代表 Gd 增强病灶在相互垂直的三个轴上的尺寸。利用所获得的线性近似函数创建的核素积累预测表,可用于在不进行术前核检查的情况下,根据 Gd-V 预测肿瘤的平均侵犯范围。
Prediction of nuclide accumulation spread based on the volume of enhancing magnetic resonance imaging lesion in glioblastoma patients.
Background: 11C-methionine-PET (MET) and Thallium-201 chloride-SPECT (TL) are useful for predictive proliferation ability and tumor invasion range identification in glioma patients, however they are not always possible in any hospital or country. Our study aimed to assess whether the range of MET and Tl accumulation could be predicted from the contrast-enhanced lesions in Gadolinium (Gd)-T1 weighted magnetic resonance image in glioblastoma multiforme (GBM) patients.
Methods: In 25 cases, the MET-area, TL-area, O-area where MET and TL overlap, and all accumulation area (AA-area) were measured in the same axial cross section as the Gd enhanced maximum area (Gd-area). This tracing operation was repeated with all axial fusion slices, and each volume was also measured (Gd-V, MET-V, TL-V, O-V, AA-V).
Results: The maximum accumulation distance of MET and TL beyond the Gd-area was limited to within 30 mm, 35 mm, respectively. Significant positive correlations were showed in all combinations with Gd-area: MET-area (r=0.851, P<0.0001), TL-area (r=0.955, P<0.0001), O-area (r=0.935, P<0.0001) and AA-area (r=0.893, P<0.0001), respectively. All combinations with Gd-V showed significant positive correlation: MET-V (r=0.867, P<0.0001), TL-V (r=0.952, P<0.0001), O-V (r=0.935, P<0.0001) and AA-V (r=0.897, P<0.0001), respectively.
Conclusions: Approximate tumor volume Gd-V can be calculated using the formula A * B * C / 2, where A, B, and C represent the dimensions of Gd-enhanced lesion in 3 axes perpendicular to each other. The nuclide accumulation predictive table created using the obtained linear approximation functions can be used to predict the average tumor invasion range from the Gd-V without preoperative nuclear examinations.
