Conventional single-pixel cameras recover images only from the data recorded in one arm of the digital micromirror device, with the light reflected to the other direction not to be collected. Actually, the sampling in these two reflection orientations is correlated with each other, in view of which we propose a sampling concept of complementary compressive imaging, for the first time to our knowledge. We use this method in a telescopic system and acquire images of a target at about 2.0 km range with 20 cm resolution, with the variance of the noise decreasing by half. The influence of the sampling rate and the integration time of photomultiplier tubes on the image quality is also investigated experimentally. It is evident that this technique has advantages of large field of view over a long distance, high-resolution, high imaging speed, high-quality imaging capabilities, and needs fewer measurements in total than any single-arm sampling, thus can be used to improve the performance of all compressive imaging schemes and opens up possibilities for new applications in the remote-sensing area.

Introduction: Injectable extended-release buprenorphine is an effective treatment for opioid use disorder (OUD), but injection site reactions (ISRs) are common treatment-emergent adverse events that may impact patient comfort, adherence, and outcome. This report examines the clinical presentation, prevalence, and management of Sublocade-related ISRs through two case studies and a review of existing literature.
Case Presentation: We present two cases of ISRs in patients receiving extended-release buprenorphine, Sublocade.

An 86-year-old woman was under follow-up at the Breast Surgery Department of our hospital for postoperative treatment for right breast cancer. During this period, a 22-mm cystic mass was identified in the pancreatic head. Its size gradually increased, and she was eventually referred to our department.

The authors describe a case of vertebral artery dissection in a patient with Turner Syndrome presenting to a university student health center. Cervical artery dissection (CeAD) is the most common cause of stroke in young adults and should be considered in patients with underlying risk factors. It usually presents with local symptoms caused by compression of adjacent nerves and their feeding vessels, as well as ischemia and hemorrhagic events.

Importance: Right anomalous aortic origin of a coronary artery (R-AAOCA) is a rare congenital condition increasingly diagnosed with the growing use of cardiac imaging. Due to dynamic compression of the anomalous vessel, invasive fractional flow reserve (FFR) during a dobutamine-atropine volume challenge (FFR-dobutamine) is considered the reference standard. A reliable alternative method is needed to reduce extensive invasive testing, but it remains uncertain whether noninvasive imaging can accurately assess the hemodynamic relevance of R-AAOCA.

Mediastinal masses often present acutely as medical emergencies, necessitating prompt and accurate diagnosis. Imaging-guided fine needle aspiration cytology (FNAC) plays a pivotal role in rapidly identifying rare mediastinal tumours and differentiating them from other potential aetiologies, enabling timely intervention. Primary mediastinal germ cell tumours (PMGCTs) constitute approximately 15% of adult mediastinal neoplasms.
