Pediatric CT Noise Texture Augmentation
<p>Dataset of routine and quarter dose anthropomorphic phantom (<a href="https://aapm.onlinelibrary.wiley.com/doi/10.1118/1.4926847">XCAT</a>) CT simulations using the <a href="https://github.com/JeffFessler/mirt">Michigan image Reconstruction Toolbox (MIRT)</a>.</p>
Repeated CT for an anthropomorphic phantom with different nasal cavity fillings
<p>Anthropomorphic head-and-neck phantom, developed at Paul Scherrer Institute in collaboration with CIRS (Computerized Imaging Reference Systems, Inc., Norfolk, USA) and made from a material equivalent to human tissue. To simulate different anatomical changes, the nasal cavities can be filled with a material equivalent to mucus, and a layer of fat can be applied to the neck to simulate weight gain/loss. The phantom has been first introduced here: DOI 10.1088/1361-6560/ac2b84</p> <p>In this repository, we include 26 different CTs presenting anatomical and/or positioning variations with respect to the reference CT. A <em>readme</em> file provides more information regarding the different CT images included in this dataset.</p>
Data from: A case-control study evaluating CT signs of xiphoid process associated with xiphodynia
<p><em>Objectives</em>:To investigate whether CT signs of the xiphoid process, such as xiphisternal angle and evidence of soft tissue compression, are useful for diagnosing xiphodynia.</p> <p><em>Design:</em>A case-control study within a cohort.</p> <p><em>Setting/Participants:</em>Participants included 1560 individuals who visited a small urban hospital in Japan for chest or abdominal pain between January 2021 and September 2023. Those who underwent CT examinations including the xiphoid process were selected. Nine individuals diagnosed with xiphodynia were assigned to the study group, while 321 individuals diagnosed with other causes of pain were assigned to the control group.</p> <p><em>Interventions:</em>The xiphisternal angle, evidence of soft tissue compression anterior to the xiphoid process, anatomical features at the tip of the xiphoid process, and anatomical morphology of the xiphoid process were compared between the two groups.</p> <p><em>Results:</em>There was no significant difference in the xiphisternal angle between the two groups. No significant differences were observed in evidence of soft tissue compression anterior to the xiphoid process or anatomical features at the tip of the xiphoid process. New anatomical signs reveal that in approximately 70% of cases, the xiphoid process curves forward and then backward.Xi</p> <p><em>Conclusions:</em>The xiphoid process sternal angle is not useful for diagnosing xiphodynia. The curvature of the xiphoid process is frequently observed regardless of the presence of xiphodynia.</p>
