Diagnostic Imaging

A new market forecast projects the global photomultiplier tubes market to expand through 2035, driven largely by demand from medical imaging equipment and particle physics research. Photomultiplier tubes, sensitive light detectors used in PET scanners and large physics experiments, are expected to see steady growth as healthcare diagnostics and scientific facilities continue to invest in detection technology, according to the report.

Vanderbilt University's medical physics program is hosting an informational webinar on November 18 for prospective students. The session will outline the program's curriculum, research opportunities, and career pathways in medical physics, and give applicants a chance to ask questions of faculty. It comes as interest grows in graduate training for the field, which supports radiation therapy and diagnostic imaging in healthcare.

New market analysis projects steady growth for the global position sensitive detectors market through 2035. Demand is being driven largely by particle physics research and expanding use of medical imaging equipment, where precise radiation and light detection are essential. The report points to ongoing investment in scientific facilities and diagnostic technologies as the main growth engines for the sector over the next decade.

Siemens Healthineers is repositioning its ultrasound business around procedural imaging, meaning ultrasound used to guide surgeries and interventions rather than primarily for diagnostics. The strategic shift is being reported by medical imaging trade press, and industry observers are weighing what it means for Siemens' diagnostic ultrasound portfolio and its competitors in the surgical and interventional imaging market.

Siemens Healthineers is withdrawing from the general imaging ultrasound business and refocusing its strategy on cardiovascular care. The move marks a significant portfolio shift for the German medical technology company, which will concentrate resources on cardiology-related imaging and diagnostics where it sees stronger growth prospects going forward.

A case report published in Cureus describes how pelvic venous disease was identified as the cause of chronic pelvic pain in a primary care setting. The authors argue the condition is often overlooked and that primary care physicians should consider it when evaluating women with long-standing pelvic pain, since imaging and timely referral can lead to effective treatment.

A case report in the Cureus Journal of Medical Science describes how an abdominal pannus, the fold of overlying abdominal tissue, delayed the detection of an abdominal wall abscess. The report highlights a diagnostic pitfall for clinicians, noting that excess abdominal tissue can obscure physical examination findings, and stresses the need for imaging when symptoms suggest infection but examination is inconclusive.

A newly published case report describes a patient with an exophytic gastric glomus tumor, a rare growth of the stomach, that went undetected on a routine gastroscopy. Doctors identified it using double contrast-enhanced ultrasonography, an imaging method that combines ultrasound with contrast agents. The report suggests this technique may help diagnose rare stomach tumors that standard endoscopy can miss.

Discussion is growing around the use of serum biomarkers in multiple sclerosis care, as clinicians look beyond MRI scans to diagnose and monitor the disease. Blood-based markers could offer a faster, less costly way to track disease activity and treatment response, complementing traditional imaging in neurology practice.
