台北医院外科医师周则中说，在超音波下如果看到胰脏肿块与扩张的胆道，医师就会安排「打药电脑断层」(CT scan with contrast)去评估能不能手术，如果有的话最好可以用正子造影/电脑断层*PET/CT)更准。但PET/CT检查，因并不是真正的同时接收正子与CT的影像资讯，会有影像和解析度的误差，以及辐射量...
Objective:To compare the diagnostic accuracy of positron emission tomography/computed tomography(PET/CT)with contrast enhanced CT(CECT)alone in the initial evaluation of cervical lymph node of patients with head and neck cancer.Methods:Fifteen consecutive patients diagnosed with a head and neck cancer ...
A whole-body 18F-FDG PET scan was performed from the skull base to the mid-thigh. The CT scan without contrast was performed immediately prior to the PET scan with a multi-detector 2-slice spiral CT scanner. For the whole-body emission scan, 9-bed positions were examined at 3 min per...
The purpose of this study was to compare lymph node (LN) staging using18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) with contrast-enhancement (CE) PET/CT and contrast-enhanced neck CT (neck CT) in patients with thyroid cancer with level-by-level compariso...
PET/CT acquisition, we performed a dual-phase (arterial and venous phase) thoracic contrast-enhanced CT (CECT) (no ECG-gating) with a non-ionic iodinated contrast agent (Iopamiro, 370 mg of iodine/ml, Bracco Sine Pharmaceutical Corp. Ltd., Shanghai, China) on the same PET/CT scanner...
探究缩短氘代-氟[18F]丙那嗪(18F-D6-AV133)PET/CT采集时间对图像质量及帕金森病诊断效能的影响,减少长时间显像造成的运动伪影。 资料与方法 回顾性选取2021年10月—2022年6月广州医科大学附属第一医院帕金森病患者27例与健康对照者2...
PURPOSE To compare the diagnostic performance of whole-body FDG PET-CT with that of contrast-enhanced CT (CE-CT) for assessment of resection stump recurrence after surgery in non-small cell lung cancer (NSCLC) patients. METHOD AND MATERIALS 98 consecutive NSCLC patients (58 males and 40 females...
Aim of the study was to quantify the economic impact of PET/CT and contrast enhanced (c.e.) CT performed in a single session examination vs. stand-alone modalities in oncological patients. One-hundred-forty-five cancer patients referred to both PET/CT and c.e. CT, to either stage (N....
