When a medical imaging exam provides a clinical benefit, the only risk that should be considered is the exam itself rather than a patient’s previous radiation exposure, according to a statement by three scientific groups representing medical physicists, radiologists, and health physicists. The American Association of Physicists in Medicine, in conjunction with the American College

Every medical specialty uses imaging. A patient might have X-rays from a ten-year-old fracture along with MRI scans and surgical photos from a recent cancer. The wealth of information affords doctors a more detailed look at a patient. Enterprise imaging brings all of the specialties together. A photograph of a melanoma by a dermatologist, say,

Researchers from the £12 million Developing Human Connectome Project have used the dramatic advances in medical imaging the project has provided to visualize and study white matter pathways, the wiring that connects developing brain networks, in the human brain as it develops in the womb. Published today in Proceedings of the National Academy of Sciences

Anabolic-androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training. AAS use increases muscle mass and strength, and its use is known

Anxiety is an adaptive response that is of great benefit to all life forms. It triggers fear learning, i.e., survival instincts that alert an organism to its surroundings and the dangers that prevail in it. However, extreme anxiety that is inappropriate to a circumstance and is prolonged is a negative emotion, labeled as a social

Visualizing Structures within Tissue To see structure within biological tissue such as organs, it is necessary to first label the tissue. Antibodies are frequently used for this purpose, and this is known as “immunolabelling”. iDISCO: Adult mouse kidney, screen capture via https://www.youtube.com/watch?v=HCdSCMlNafk Antibodies are specific to certain “markers”, or antigens, and immunolabelling is used for

Diagnosing the degree of vision impairment is a difficult task for even experienced optometrists, since it depends on the subjective response of the person tested. Normally, it is based on reading out or describing letters or shapes on an eye chart. In many cases the person may not actually be reading out the letter seen,

Diagnostic imaging has been a widely used tool in the detection and treatment of various diseases. Dual-energy computed tomography (DECT) is an emerging imaging technique that combines information collected with various x-ray energy fields.

A first-in-human study presented at the Society of Nuclear Medicine and Molecular Imaging 2020 Annual Meeting has demonstrated the safety, favorable pharmacokinetic and dosimetry profile of 64Cu-EBRGD, a new, relatively long-lived PET tracer, in patients with glioblastomas. The radiotracer proved to be a superior, high-contrast imaging diagnostic in patients, visualizing tumors that express low or

Brain imaging may one day be used to help diagnose mental health disorders—including depression and anxiety—with greater accuracy, according to a new study conducted in a large sample of youth at the University of Pennsylvania and led by Antonia Kaczkurkin, Ph.D. and Theodore Satterthwaite, MD. And knowing more about the neurobiology behind psychiatric disorders could

Using a non-invasive imaging technique that measures the stiffness of tissues gives crucial new information about cancer architecture and could aid the delivery of treatment to the most challenging tumours, new research shows. Magnetic resonance elastography was able to visualise and measure how stiff and dense tumours are in mice. The technique, which can be

A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial. The imaging system enables neurosurgeons to better see malignant growths that often are difficult to fully eliminate. Results from the multi-institutional clinical trial, led by investigators from Cedars-Sinai and sponsored by

Siemens and SAS are partnering up for an artificial project that will develop new analytics for cloud and edge computing, combining SAS’ open source streaming analytics through Siemens’ MindSphere IoT platform. It’s one of two big AI partnerships announced this week by Siemens, whose Healthineers division is also working with Intel on a cardiac MRI

THURSDAY, Dec. 20, 2018 — A miniaturized optical coherence tomography (OCT) imaging needle can detect blood vessels intraoperatively in the human brain in vivo, according to a study published online Dec. 19 in Science Advances. Hari Ramakonar, M.B.B.S., from Sir Charles Gairdner Hospital in Nedlands, Australia, and colleagues developed an imaging needle that is able

A research team led by Prof. Zheng Hairong from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences developed a dual-step iterative temperature estimation (DITE) method for fat-referenced PRFS temperature imaging in fat-containing tissues. Magnetic resonance thermometry (MRT) is the only imaging technique that noninvasively provides temperature distribution in vivo. The

(HealthDay)—Patients with prostate cancer receiving care in a Medicare-only setting are more likely to receive guideline-discordant imaging, according to a study published online Aug. 17 in JAMA Network Open. Danil V. Makarov, M.D., from New York University School of Medicine in New York City, and colleagues examined the correlation between prostate cancer imaging rates and

(HealthDay)—Doctors’ intuition plays a role in determining how many imaging tests are ordered for a patient, according to research presented at the 40th International Conference of the IEEE Engineering in Medicine and Biology Society, held from July 17 to 21 in Honolulu. Mohammad M. Ghassemi, Ph.D., from the Massachusetts Institute of Technology in Boston, and

Guided by glowing bacteria, researchers have devised an imaging technique that can diagnose live tuberculosis in an hour and help monitor the efficacy of treatments. That’s particularly critical because many TB strains have evolved defenses against standard treatments. Jianghong Rao, PhD, a professor of radiology at Stanford who led the work, says that speedy TB

About a third of epilepsy sufferers require treatment through surgery. To check for severe epilepsy, clinicians use a surgical procedure called electrocorticography (ECoG). An ECoG maps a section of brain tissue to help clinicians identify areas damaged by seizures. “But ECoG requires taking a part of your skull out and putting electrodes directly on brain

Working with hundreds of time-lapse videos of mouse tissue, a team of biologists joined up with civil engineers to create what is believed to be the first 3-D computer model to show precisely how the tiny tubes that funnel milk through the breasts of mammals form. A report on the model was published April 9
