一项前瞻性双盲对比试验的结果显示,与磁共振成像技术(MRI)相比,应用显像药物~(18)F-脱氧葡糖的正电子发射断层扫描(~(18)F-FDG-PET)与X射线计算机体层扫描(CT)结合的人体诊断成像可以显著地提高肿瘤分期的准确度。来自于德国Essen大学附属医院的Gerald Antoch医生及其同事在为期11个月的研究中分别对98例患者进行了FDG-PET/CT和MRI的全身诊断成像以对比确定肿瘤的分期精度,其中82例患者为原发肿瘤期,16例为可疑的肿瘤复发期。在年龄范围为27-94岁的受试患者中,支气管肺癌29例、不明原发肿瘤12例、头颈部肿瘤13例、眼色素层黑素瘤13例、泌尿生殖系肿瘤8例;此外,胃肠道
Results of a prospective, double-blind comparative study showed that positron emission tomography (~ (18) F-FDG imaging with ~ (18) F-deoxyglucose, compared with magnetic resonance imaging -PET) Human diagnostic imaging combined with X-ray computed tomography (CT) can significantly improve the accuracy of tumor staging. Gerald Antoch, MD, from the Affiliated Hospital of Essen, Germany, and colleagues conducted a total of 98 patients undergoing whole-body FDG-PET / CT and MRI imaging in a 11-month study to determine the stage of tumor staging accuracy. Of these, 82 Cases of patients with primary tumor stage, 16 cases of suspected tumor recurrence. In the age range of 27-94 years of patients, 29 cases of bronchial lung cancer, 12 cases of unknown primary tumor, 13 cases of head and neck cancer, 13 cases of uveal melanoma, urogenital tumors in 8 cases; in addition Gastrointestinal
