Megavoltage computed tomography (MVCT) images acquired during each radiotherapy session may be useful for delta radiomics. However, no studies have examined whether the MVCT-based radiomics has prognostic power. Therefore, the purpose of this study was to examine the prognostic power of the MVCT-based radiomics for head and neck squamous cell carcinoma (HNSCC) patients. 100 HNSCC patients who rece...... hiện toàn bộ
Development of an algorithm to automatically compress a CT image to visually lossless thresholdBMC Medical Imaging - - 2018
Chang-Mo Nam, Kyong Joon Lee, Yousun Ko, Kil Joong Kim, Bohyoung Kim, Kyoung Ho Lee
To develop an algorithm to predict the visually lossless thresholds (VLTs) of CT images solely using the original images by exploiting the image features and DICOM header information for JPEG2000 compression and to evaluate the algorithm in comparison with pre-existing image fidelity metrics. Five radiologists independently determined the VLT for 206 body CT images for JPEG2000 compression using Q...... hiện toàn bộ
Imaging of thyroid tumor angiogenesis with microbubbles targeted to vascular endothelial growth factor receptor type 2 in miceBMC Medical Imaging - Tập 13 - Trang 1-9 - 2013

To evaluate whether Contrast Enhanced Ultrasund (CEUS) with microbubbles (MBs) targeted to VEGFR-2 is able to characterize in vivo the VEGFR-2 expression in the tumor vasculature of a mouse model of thyroid cancer (Tg-TRK-T1). Animal protocol was approved by Institutional committee on Laboratory Animal Care. Contrast-enhanced ultrasound imaging with MBs targeted with an anti-VEGFR-2 monoclonal ant...... hiện toàn bộ
Tracking of In-111-labeled human umbilical tissue-derived cells (hUTC) in a rat model of cerebral ischemia using SPECT imagingBMC Medical Imaging - Tập 12 - Trang 1-15 - 2012

In order to increase understanding of how infused cells work, it becomes important to track their initial movement, localization, and engraftment efficiency following transplantation. However, the available in vivo cell tracking techniques are suboptimal. The study objective was to determine the biodistribution of intravenously administered Indium-111 (In-111) oxine labeled human umbilical tissue-...... hiện toàn bộ
Repeatability and reproducibility of cerebral 23Na imaging in healthy subjectsBMC Medical Imaging - Tập 19 - Trang 1-7 - 2019

Initial reports of 23Na magnetic resonance imaging (MRI) date back to the 1970s. However, methodological challenges of the technique hampered its widespread adoption for many years. Recent technical developments have overcome some of these limitations and have led to more optimal conditions for 23Na-MR imaging. In order to serve as a reliable tool for the assessment of clinical stroke or brain tum...... hiện toàn bộ
