African Americans, Hispanics less likely to receive recommended lung cancer imaging

A University of Colorado Cancer Center study found that African American patients were half as likely as non-Hispanic whites to receive PET-CT imaging for non-small cell lung cancer, while Hispanics received it 70% as frequently. This disparity may be due to limited access to specialized imaging equipment and unconscious bias.

Ultra-wide field retinal imaging techniques cannot be used interchangeably

A new study from the Joslin Diabetes Center reveals that ultra-wide field (UWF) fluorescein angiography detects over three times more microaneurysms than UWF color imaging, highlighting the need for cautious use of these techniques when evaluating and treating diabetic retinopathy. The research also suggests that AI can automate the gr...

AJR: Novel coronavirus (COVID-19) imaging features overlap with SARS and MERS

COVID-19 imaging features exhibit variable and nonspecific characteristics, but also share similarities with those of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Initial chest imaging abnormalities are common, affecting at least 85% of patients, often displaying bilateral lung involvement.

Researchers capture moving object with ghost imaging

Ghost imaging allows forming images with lower light levels but has been limited to stationary objects due to blurring from movement. Researchers developed a new method combining blurry image information with object location data to capture high-quality images of moving objects using ghost imaging.

Use of medical imaging

The study analyzed 135 million imaging examinations among 16-21 million patients in the US and Canada, finding increased medical imaging rates among adults but declining nuclear medicine use. Imaging rates continued to rise among children except for CT, which declined since 2006.

Computational approach speeds up advanced microscopy imaging

Researchers have developed a way to enhance the imaging speed of two-photon microscopy up to five times without sacrificing resolution. By combining compressive sensing with a faster scanning method, scientists can now observe biological phenomena that were previously too fleeting to image with current state-of-the-art microscopy.

In vivo super-resolution photoacoustic computed tomography by localization of single dyed droplets

Researchers at Caltech Optical Imaging Laboratory created a technique to break the acoustic diffraction limit in PACT by localizing single dyed droplets flowing in blood vessels, achieving six-fold finer resolution. The droplets provide excellent tracers for super-resolution imaging and enable tracking of blood flow speed.
