October 3, 2024 by Denise Heady, University of California, Los Angeles A new study led by investigators from the UCLA Health Jonsson Comprehensive Cancer Center has demonstrated a new, non-invasive imaging technique can accurately detect clear-cell renal cell carcinoma, the most common form of kidney cancer. The findings, published in The Lancet Oncology, could greatly...

A ‘Google Earth’ view of bone—with an eye toward disease prevention
September 26, 2024 by Eric Williamson, University of Virginia Everyone knows that we can view the broad structures of our bones in the body by taking X-rays. Yet that’s just scratching the surface. Science now has a host of new imaging and characterization techniques to go deeper, and define more narrowly, the architecture and relative...

A new method makes high-resolution imaging more accessible
Labs that can’t afford expensive super-resolution microscopes could use a new expansion technique to image nanoscale structures inside cells Peer-Reviewed Publication Massachusetts Institute of Technology A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it...

Novel PET imaging tool identifies early signs of inflammatory bowel disease and predicts response to treatment
July 25, 2024 by Society of Nuclear Medicine and Molecular Imaging Visual Abstract. Active bowel inflammation disrupts the bowel cell lining, which causes the inflammatory T cells to secrete Granzyme B into the extracellular space, progressively accentuating the inflammatory response through a feed-forward mechanism. In the normal or non-inflamed bowel, there is no extracellular Granzyme...

Researchers develop method to monitor patients with spinal muscular atrophy using sound waves
MAY 15, 2024 by Friedrich–Alexander University Erlangen–Nurnberg Credit: Med (2024). DOI: 10.1016/j.medj.2024.02.010Spinal muscular atrophy (SMA) is a terrible disease in which a genetic mutation causes certain nerves responsible for sending signals to muscles to degenerate. This leads to muscles wasting away, and many patients have died a painful death due to this rare condition. Genetic...

Imaging with radio-labeled tracer correlates with identification of early-stage endometriosis by laparoscopic surgery
by University of Oxford Credit: Sora Shimazaki from PexelsResearch presented at The Society for Reproductive Investigation Meeting summarized preliminary findings from patients with known or suspected endometriosis who were imaged with a SPECT-CT camera and subsequently underwent planned laparoscopic surgery, a key-hole surgical procedure to establish the presence, absence and location of endometriotic lesions. The...

Researchers develop an ultrasensitive broadband transparent ultrasound transducer
by Pohang University of Science and Technology Ultrasound-photoacoustic dual modal imaging of TUT and mouse abdomen. Credit: POSTECHThe ‘ultrasound-photoacoustic dual-modal imaging system’ combines molecular imaging contrast with ultrasound imaging, and it can visualize molecular and structural information inside the body in real time without any ionizing radiation. This advantage gives it the potential to enhance...
