An unexpected discovery surprised a scientist: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment -- much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust -- in addition to its use in drug delivery to treat tumor cells -- one day become a novel contrast agent used for MRI ..read more

A new study showed that a non-invasive imaging test can help identify patients with coronary artery blockage or narrowing who need a revascularization procedure ..read more

Researchers applied artificial intelligence (AI) to a technique that produces high-resolution images of cells in the eye. They report that with AI, imaging is 100 times faster and improves image contrast 3.5-fold. The advance, they say, will provide researchers with a better tool to evaluate age-related macular degeneration (AMD) and other retinal diseases ..read more

A new expert consensus statement aims to improve endometriosis evaluation. Endometriosis is a common condition with substantial diagnostic delay, leading patients to experience pain, infertility, lost wages and interrupted relationships. The consensus provides recommendations for augmenting routine pelvic ultrasounds through additional maneuvers and imaging to improve diagnosis of deep endometriosis ..read more

Trial findings suggest that the less invasive approach to heart bypass surgery offers comparable safety and efficacy to established methods and that safety issues inherent to invasive catheterisation investigation can be replaced by a non-invasive technique using CT scan imaging and AI-powered blood flow analysis ..read more

Researchers describe a new technique for the minimally invasive removal of benign tumors located in the challenging posterior head of the pancreas (right side of abdomen, nestled in the curve of the duodenum (or first part of the small intestine). The technique, called the retro-laparoscopic approach, allows surgeons to safely and effectively remove these tumors without removing healthy pancreatic tissue, thereby preserving organ functionality ..read more

Researchers have developed a new, interpretable artificial intelligence (AI) model to predict 5-year breast cancer risk from mammograms, according to a new study ..read more

By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system. Researchers demonstrate the efficacy of ultrasound technology to detect low-amplitude movements produced by vocalizations at the surface of the chest. They also demonstrated the possibility of using the airborne ultrasound surface motion camera to map these vibrations during short durations so as to illustrate their evolu ..read more

Researchers have developed a photoacoustic imaging watch for high-resolution imaging of blood vessels in the skin. The wearable device could offer a non-invasive way to monitor hemodynamic indicators such as heart rate, blood pressure and oxygen saturation that can indicate how well a person's heart is working ..read more
