Introd.ction: CT alone cannot provid. sufficient information referring to response after neoad.uvant therapy in a timely manner. To evaluate the role of 18F-Fd.-PET after neoad.uvant chemorad.ation as a valid. non-invasive pred.ctor for early therapy response and.its effect on survival as compared.to histopathologic tumor response, d.ta of 32 of 210 rand.mized.patients with NSCLC stage IIIA/IIIB, who were treated.in a?prospective rand.mized.controlled.multicenter trial (LUCAS- Md., were re-evaluated. Material and.Method.: For 32 patients with NSCLC stage IIIA (44%) IIIB (56%) neoad.uvant treatment consisted.of two to three cycles of chemotherapy (225 mg/m2 paclitaxel and.carboplatin AUC 6 d.q22) and.concomitant chemorad.ation (50 mg/m2 paclitaxel and.carboplatin AUC 2 d., d., d.5;1.5 Gy b.i.d. up to 45 Gy). d.cumentation of involved.lymph nod. stations as d.tected.by 18F-Fd.-PET/CT and.lymph nod. sampling d.ring surgery accord.ng to the IASLC lymph nod. mapping (2009). Evaluation of histological regression grad. (RG) accord.ng to Junker et al. (2001) and.correlation with?18F-Fd.-PET/CT for primary tumor and.each lymph nod. station. Calculation of d.sease free survival using Kaplan-Meier estimates and.log rank tests. Results: Actuarial tumor specific survival for the 32 patients with concomitant chemorad.ation plus?chemotherapy: complete vs. incomplete metabolic remission prior to surgery after 60 months:?40% vs. 24% (p?= 0.018). RG III/IIb (no/less than 10% of vital tumor cells) vs. RG IIa/I (more than 10% vital tumor cells) after 60 months: 46% vs. 15% (p?= 0.006). 18/32 (56%) patients had.RG III/IIb, 8/32 (25%) patients had.regression grad. III. 1/8 pts. with RG III were in the 18F-Fd.- PET/CT false positive, 10 pts. with RG IIb (i.e. all pts. with RG IIb) were in the 18F-Fd.-PET/CT false negative. One patient with RG IIa was in the 18F-Fd.-PET/CT false negative. Hence, the cut-off level in d.tecting vital tumor cells by 18F-Fd.-PET/CT after neoad.uvant chemorad.a

评价比较前瞻性心电门控横断面CT冠状动脉成像(PGA)和回顾性心电门控螺旋技术(RGH)的图像质量和曝光剂量。40例可疑冠状动脉疾病病人,心率控制在65次以下,用64层CT进行CT冠状动脉成像。将其分成2组,前20例用PGA技术,后20例用RGH技术。2组病人根据年龄、性别、体质量指数和心率进行配对。每组均由2位独立的观察者对冠状动脉各段的图像质量进行评价,并将其分为1(无法评估)～5(优秀质量)度。
