Proton therapy treatment for lungs remains challenging as images enabling the detection of inter- and intra-fractional motion, which could be used for proton dose adaptation, are not readily available. 4D computed tomography (4DCT) provides high image quality but is rarely available in-room, while in-room 4D cone beam computed tomography (4DCBCT) suffers from image quality limitations stemming mostly from scatter detection. This study investigated the feasibility of using virtual 4D computed tomography (4DvCT) as a prior for a phase-per-phase scatter correction algorithm yielding a 4D scatter corrected cone beam computed tomography image (4DCBCT), which can be used for proton dose calculation.

Acute subdural hematoma (SDH) occurs following severe head trauma with brain contusion or rupture of bridging veins. Conversely, SDH caused by rupture of a cortical artery without trauma or with minor trauma is also possible. Although over 150 cases of the latter SDH have been reported, they were predominantly diagnosed only during surgery, and therefore, no adequate histological evaluation has been performed. Read More

Although neoadjuvant chemotherapy (NAC) is a crucial component of treatment for locally advanced breast cancer (LABC), only about 70% of patients respond to it. Effective adjustment of NAC for individual patients can significantly improve survival rates of those resistant to standard regimens. Thus, the early prediction of NAC outcome is of great importance in facilitating a personalized paradigm for breast cancer therapeutics. Read More

Introduction And Importance: Blunt abdominal aortic injury (BAAI) resulting from blunt abdominal trauma is rare; therefore, there are no standard guidelines for its treatment. Herein, we report the successful treatment of BAAI via endovascular aortic repair (EVAR) performed immediately after emergency laparotomy to repair a bowel injury.Case Presentation: A 78-year-old man was injured after being caught between a shovel car and the bumper of his own car for approximately 15 s.

Objective: Retrotransverse foramen (RTF) and Retrotransverse groove (RTG) are anatomic variations of the atlas (C1) vertebrae , RTF contained an anastomotic vein connecting atlanto-occipital and atlanto-axodian venous sinuses. The purpose of this study is to analyze the arterial vascular structures running though the RTF and RTG.Methods: Three-dimensional Volume Rendered Computed Tomography Angiography (3D VR CTA) images of 427 subjects (264 males, 163 females, aged between 17 and 87 years) were reviewed and evaluated by using Radiant DICOM Viewer.
