Authors: Zhang L, Luo Z, Wang H, Ren L, Yu F, Guan T, Fu S Abstract Palpation of the seventh cervical vertebra (C7) is important for the diagnosis and treatment of neck and chest conditions. However, the spinous process of C7 (C7-SP) displays an anatomical deviation among individuals. The present study aimed to clarify anatomic characteristics of C7-SP by using a three-dimensional (3D) computed tomographic (CT) reconstruction technique. A total of 245 subjects meeting the selection criteria were examined. After CT scanning, the images were reconstructed in 3D. All subjects were grouped according to their deviation ...

Dual Energy Computed Tomography Scans of the Bowel: Benefits, Pitfalls, and Future Directions. Radiol Clin North Am. 2018 Sep;56(5):805-819 Authors: Yeh BM, Obmann MM, Westphalen AC, Ohliger MA, Yee J, Sun Y, Wang ZJ Abstract Current computed tomography bowel imaging is challenging given the variable distension, content, and location of the bowel, the different appearance of tumors within and adjacent to bowel, and peristaltic artifacts. Published data remain sparse. Derangements in enhancement may be highlighted, image artifacts reduced, and radiation dose from multiphase scans minimized. This m...

Abstract Lower gastrointestinal bleeding is defined as occurring distal to the ligament of Treitz and presents as hematochezia, melena, or with anemia and positive fecal occult blood test. Imaging plays a pivotal role in the localization and treatment of lower gastrointestinal bleeds. Imaging tests in the workup of acute lower gastrointestinal bleeding include computed tomography (CT) angiography, nuclear medicine scintigraphy, and conventional catheter angiography. Catheter angiography can also be used to deliver treatment. Imaging tests in the workup of occult lower gastrointestinal bleeding include CT enterogra...

Abstract Positron emission tomography (PET)/computed tomography (CT) with 2-deoxy-2-[18F]fluoro-d-glucose (FDG) has become the standard of care for the initial staging and subsequent treatment response assessment for numerous gastrointestinal malignancies. However, it is often supplemented by magnetic resonance imaging (MRI) for local tumor staging. Hybrid PET/MRI scanners, which acquire PET data and MRI data simultaneously, have the potential to provide accurate whole-body staging in a single examination. Furthermore, to address certain limitations of FDG, many new PET tracers have been developed to probe distinc...

AbstractImmune checkpoint inhibitors (ICI) have revolutionized therapy of metastatic melanoma. The first ICI was ipilimumab, a cytotoxic T lymphocyte-associated Ag 4 (CLTA-4) inhibitor with response rates of approximately 11% and disease control of 22%. The programmed cell death 1 (PD-1) inhibitors, such as pembrolizumab and nivolumab, led to longer progression-free survival and overall survival rates with fewer side effects. Molecular imaging techniques, such as positron emission tomography –computed tomography (PET–CT) with 2-deoxy-2-(18F)fluoro-d-glucose (18F-FDG) are in use for staging and therapy monitorin...

ConclusionIn this retrospective cohort study, we could conclude that a delay from initial diagnosis confirming a CSDH to surgical evacuation had no negative effect on outcome when surgery was performed within the time frames and on patients with pre-operatively favorable GCS scores ( ≥ 13) outlined in our study.
