The U.S. FDA cleared respiratory imaging technology company 4dmedical Ltd.’s computed tomography lung ventilation analysis software (CT LVAS) that is nearly identical to its X-ray velocimetry technology but uses CT imaging and provides greater access to the four-dimensional imaging technology.

Emvision Medical Devices Ltd.’s stroke helmet correctly identified hemorrhagic stroke patients and differentiated between patients without hemorrhage, interim clinical results show.

No matter how you look at it, guiding percutaneous coronary interventions to treat complex lesions with optical coherence tomography (OCT) or intravascular ultrasound (IVUS) produces similar results in patients with complex lesions, a study presented Oct. 23 at the Transcatheter Cardiovascular Therapeutics (TCT) annual meeting in San Francisco indicated.

The U.K. has launched the first-of-its-kind national total-body positron emission tomography (PET) imaging platform that will be ‘game-changing’ for clinical research. Funded with £32 million (US$39 million) from the government, the National PET Imaging Platform (NPIP) will enable clinicians and researchers to access never-before-seen data that will improve the detection, diagnosis and treatment of complex, multi-organ diseases.

An artificial intelligence (AI) tool developed by Annalise.ai Pty Ltd. was able to improve radiologists’ accuracy in detecting abnormalities on non-contrast computed tomography brain (CTB) scans. According to a study published in European Radiology, the Annalise Enterprise CTB module improved radiologists' accuracy by 32% and reduced their overall reading time by 11%.

A fluorescent imaging agent developed by Vergent Bioscience Inc. enables visualization of elusive and previously undetected tumors, a phase II study presented last week at the 2023 World Conference on Lung Cancer (WCL23) demonstrated. The ability of the tumor-targeting agent, Vgt-309, to illuminate tumors could help surgeons more precisely locate tumors, better ensure clean margins and guide care decisions. In 10% of cases, the agent revealed unknown tumors in lymph nodes, which could affect which nodes are biopsied as well as when or whether a systemic therapy is recommended.

The Medical Imaging & Technology Alliance (MITA) has filed its comments for two draft Medicare rules, citing ongoing concerns over how Medicare pays for a variety of aspects of medical imaging procedures. MITA’s executive director, Patrick Hope, said the Medicare hospital outpatient program is overdue for an overhaul of its packaging policy for payments for radiopharmaceuticals and that the Medicare physician fee schedule should be insulated from further cuts for the professional component of imaging procedures, changes Hope said are necessary to ensure continued patient access to these services.
