Assessing Pulmonary Embolisms on Unenhanced CT Images Using Electron Density Images Derived from Dual-Layer Spectral Detector CT: A Single-centre Prospective Study Conducted at the Emergency Department.
Curr Med Imaging
January 2025
Department of Radiology, Peking Union Medical College Hospital [PUMCH], Chinese Academy of Medical Sciences & Peking Union Medical College [CAMS & PUMC], China.
Aims To evaluate the utility of unenhanced spectral imaging, electron density (ED) and overlay electron density (OED) images for assessing pulmonary embolisms in patients with suspected or confirmed acute pulmonary embolism (APE). Background Multiple spectral images can be extrapolated from spectral detector CT (SDCT), ED and OED images. ED and OED images are highly sensitive to moisture-rich tissues.

Ann Med
December 2025
Department of Neurology, West China Hospital, Sichuan University, Chengdu, China.
Background: We systematically reviewed neuroimaging predictors for malignant brain oedema (MBE) after thrombectomy in patients with ischemic stroke.
Methods: We searched MEDLINE and EMBASE in November 2023 for studies of patients with ischemic stroke. We included studies investigating neuroimaging predictors or prediction models for MBE after thrombectomy.
Evaluation of the location of posterior superior alveolar artery and infraorbital foramen originating from the same source by using cone beam computed tomography.
BMC Oral Health
January 2025
Faculty of Dentistry Department of Oral and Maxillofacial Radiology, Ondokuz Mayıs University, Atakum/Samsun, Turkey.
Aim: This study aimed to evaluate the prevalence, location and diameters of Posterior superior alveolar artery (PSAA) and Infraorbital foramen (IOF) to find out whether there is any relationship between PSAA and IOF, and to predict their location relative to each other in surgical procedures by using cone beam computed tomography (CBCT).
Material And Method: Bilateral maxillary sinuses were analysed retrospectively in 170 patients with no missing teeth in the maxillary posterior region. The largest locations of PSAA and IOF in the maxillary sinus were determined and their size, shape, location in relation to the teeth and distances from anatomical points were evaluated.
[Recent clinical studies and the S3 guidelines on stroke].
Radiologie (Heidelb)
January 2025
Klinik für diagnostische und interventionelle Neuroradiologie, 66421, Homburg, Deutschland.
Background: Treatment of patients with acute stroke requires hospitalization. Cooperation of neurologists, neuroradiologists, intensive care physicians, internists, and cardiologists is required to achieve best possible outcome.
Objective: A summary of the current recommendations for stroke treatment is provided.
An iliac arteriovenous fistula associated with leg swelling 2 years after the removal of a hemodialysis catheter: A case report.
Medicine (Baltimore)
January 2025
The Third Hospital of Mianyang, Sichuan Mental Health Center, Mianyang, Sichuan, China.
Rationale: Temporary central venous catheters are commonly used for patients who require emergency hemodialysis. In rare instances, this procedure can result in a very serious complication known as arteriovenous fistula (AVF). Although some cases of femoral arteriovenous fistula have been reported previously in the literature; however, the incidence of iliac AVF precipitated by a hemodialysis catheter is exceedingly uncommon.
