Immune checkpoint inhibitors activate the body's immune system against tumors. Although this cancer treatment has shown remarkable success, the patient's chance of responding to the treatment remains unpredictable. Scientists at the University Medical Center Groningen have performed whole-body PET scans u...
❝The recent extension of the WB-PET concept to imaging extended axial imaging ranges with larger FOV systems, colloquially refered to as a total-body PET (TB-PET) has sparked interest in the PET community to conduct multi-organ systemic investigations. 最近将WB-PET概念扩展到具有更大FOV系统的...
This issue will become less important as PET-tomograph manufactures continue to improve their speed, potentially reducing the PET whole-body scan time to 5 min or less (Nahmias et al., 2002). These hybrid machines have raised new issues concerning the training and licensing of the technologists...
TB-PET systems cover axial scan ranges of 1m to 2m, which allows the synchronous measurement of signals from multiple organs. TB-PET系统覆盖1m至2m的轴向扫描范围,允许同步测量来自多个器官的信号。可以推测,WB可能是多床位的一种扫描,只能构建静态PET无法短时间构建动态PET图像。换句话说,TB的detector的axia...

To compare [18 F]FDG PET/MRI with PET/CT for the assessment of bone lesions in oncologic patients. Methods This prospective study included 67 patients with solid tumours scheduled for PET/CT with [18 F]FDG who also underwent a whole-body PET/MRI scan. The datasets (PET/CT, PET/MRI...
Subsequently, five whole-body (covering head-to-toe) PET scans (voxel size = 4.69 × 4.69 × 2.78 mm) were acquired. The PET scans were acquired in time-of-flight mode, and each scan was immediately preceded by a 3D dual-echo water-fat separated MR attenuation correction scan (...
Combined whole-body (WB) PET/CT imaging provides better overall co-registration compared to separate CT and PET. However, in clinical routine local PET-CT mis-registration cannot be avoided. Thus, the reconstructed PET tracer distribution may be biased when using the misaligned CT transmission data...
