Consensus Criteria for PET-Based Treatment Response

Selected articles obtained using Internet search tools, including PubMed and syllabi from meetings (e.g., Clinical PET and PET/CT syllabus, Radiological Society of North America, 2007), were identified. Publications resulting from database searches and including the main search terms RECIST, positron, FDG, ROI (region of interest), cancer, lymphoma, PET, WHO, and treatment response were included. The search strategy for relevant ¹⁸F-FDG PET studies articulated by Mijnhout et al. was also applied (34 (link),35 (link)). These were augmented by key references from those studies, as well as the authors' own experience with PET assessments of treatment response, informal discussions with experts on PET treatment response assessment, and pilot evaluations of clinical data from the authors' clinical practice. Limitations and strengths of the anatomic and functional methods to assess treatment response were evaluated with special attention to studies that had applied qualitative or quantitative imaging metrics, had determined the precision of the method, and had histologic correlate or outcome data available. On the basis of these data, proposed treatment response criteria including PET were formulated, drawing from both prior anatomic models (notably WHO, RECIST, and RECIST 1.1) and the EORTC PET response draft criteria (36 (link)). These conclusions were based on a consensus approach among the 4 authors. Thus, a systematic review and a limited Delphilike approach augmented by key data were undertaken to reach consensus in a small group. For demonstration purposes, ¹⁸F-FDG PET scans obtained at our institution on 1 of 2 GE Healthcare PET/CT scanners were analyzed with several tools, including a tool for response assessment.

Tracing EGFP-Positive Neuronal Circuits

C57BL/6J male mice at age P56 were injected with EGFP-expressing AAV using iontophoresis by the stereotaxic method. The brains were scanned using the STP tomography systems. Images were subject to data quality control and all the injection sites were manually annotated. All the image sets were co-registered into the 3D reference space. EGFP-positive signals were segmented from background, and binned at voxel levels for quantitative analyses. The raw connectivity data are served with various navigation tools on the web through the Allen Institute’s data portal. See the full Methods section for detailed descriptions.

Coconut Growth Observation using CT Scanning

In order to continuously observe the growth process of the coconut fruit, we first number the sample coconut fruit, then mark the posture position of the coconut fruit to ensure that it was in a fixed position in each scan. Then we used CT scanning to obtain the corresponding coronal scan image of each coconut fruit (Fig. 2b).
The coconuts were placed on a plastic shelf. Text and arrow markers were used so that the orientation of the image remained consistent throughout the cycle. The image was obtained using a 256 dual source CT scanner (Scanning instrument: SIEMENS SOMATOM Definition Flash) with the following parameters: tube voltage: 120 kV, tube current: 250 mas, temperature: 24

Multimodal CT Imaging for Acute Stroke

Baseline CT imaging included brain non-contrast CT, CTP, and CTA, obtained with different CT scanners (64, 128, 256, or 320 detectors, with Toshiba [Tokyo, Japan], Siemens [Munich, Germany], or GE [Cleveland, OH, USA] scanners). The axial coverage ranged from 80 to 160 mm.
The CTP data were processed by commercial software MIStar (Apollo Medical Imaging Technology, Melbourne, Vic, Australia). CTP parameters were generated by applying the mathematical algorithm of singular value decomposition with delay and dispersion correction (20 (link), 21 (link)). The following four CTP parameters were generated: cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), and delay time (DT). The penumbra and core volume were measured on acute CTP with dual threshold setting (22 (link)): DT at the threshold of 3 s for whole ischemic lesion volume and CBF at the threshold setting of 30% for acute core volume. The collateral index was defined by the ratio of DT >6 s/DT >2 s volume.
