Reducing radiation in CT imaging

Emergency physicians who evaluate patients with non-specific chest pain using whole chest multi-detector CT combined with retrospective electrocardiogram gating can reduce the patient radiation dose.

Single protein dimers wavering observed with imaging technology

Researchers have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one natural three-dimensional structure, can actually twist itself into a second form.

Imaging advance: Cellomics ToxInsight IVT Platform

Cellomics ToxInsight Solution offers a unique combination of imaging hardware and analysis software, and couples pre-validated panels of...

Imaging obvserves memories being made

A recent study has captured an image for the first time of a mechanism, specifically protein translation, which underlies long-term memory formation.

Brain energy use key to understanding consciousness

High levels of brain energy are required to maintain consciousness, a finding which suggests a new way to understand the properties of this still mysterious state of being, researchers report.

Prototype Breast Cancer Imaging System

A prototype breast imaging system combining positron emission tomography and magnetic resonance imaging technologies could greatly improve breast cancer imaging capabilities, according to researchers.

High-Quality Images of Small Tumours

A new study shows that combining high resolution and high sensitivity collimation provides better quality images when using single photon emission computed tomography scans, said researchers.

Hybrid scanner imaging breakthrough

A major barrier to developing a hybrid positron emission tomography/magnetic resonance imaging system could be removed by using a novel approach for reconstructing data

New chemistry techniques improves imaging

A new PET/MR imaging system has been developed that can successfully provide whole-body images of rats and other small animals and could greatly improve imaging capabilities and advance research in many areas.

3-D structure of key nuclear pore block

In new research, scientists have for the first time glimpsed in three dimensions an entire subcomplex of the nuclear pore complex, an innovation fundamental to the development of nearly all multicellular life on earth.

Determining cancer therapy success

A simple magnetic resonance imaging test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers.

Assessing breast cancer treatment

Non-invasive imaging can measure how well patients with breast cancer respond to standard aromatase inhibitor therapy after only two weeks.

Past experience is invaluable for decisions

Researchers have shown that past experience really does help when we have to make complex decisions based on uncertain or confusing information.

Visualizing virus replication in 3D

Scientists at the Hygiene Institute at Heidelberg University Hospital were the first to present a three-dimensional model of the location in the human cell where the virus is reproduced.

CT scans increase cancer risk estimates

Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam, according to researchers.

3T MRI detects early breast cancer

3T MRI, a powerful tool for evaluating patients with a high risk of having breast cancer, can detect a significant number of lesions not found on mammography and sonography.

BioScope Catalyst

The completely integrated, open-access design and exclusive Microscope Image Registration and Overlay capability fully leverages the power of both light microscopy and AFM.

Super-resolution video imaging

A team of researchers has developed a microscope that is capable of live imaging at double the resolution of fluorescence microscopy using structured illumination.

The structure of a giant virus

Scientists have determined the basic design of the mimivirus's outer shell, or capsid, and also of the hundreds of smaller units - called capsomeres - making up this outer shell.

Identifying pelvic lymph nodes in women

Diffusion weighted MR can accurately identify benign from malignant pelvic lymph nodes in patients with gynecologic malignancy.
