A large international study has shown that an MRI scan can reduce the number of invasive prostate biopsies by up to 28%. The PRECISION trial shows that using MRI to target prostate biopsies leads to more of the harmful prostate cancers, and fewer harmless cancers being diagnosed.
The University of Texas MD Anderson Cancer Center and RaySearch Laboratories today announced a strategic alliance with the aim of enhancing cancer radiation therapy through several initiatives, including more precisely targeting of tumors and improving upon, and making more available, an existing radiation therapy called adaptive radiation therapy, currently only used at highly specialized care centers.
Shanghai United Imaging Healthcare Co. Ltd. and RaySearch Laboratories AB have entered into a collaboration within which RaySearch’s treatment planning system RayStation and radiation oncology system RayCare will be adapted to support the UIH linear accelerators.
In a collaborative, multi-institutional study published by JAMA Oncology, researchers from the University of Alabama at Birmingham, University of Chicago, and National Cancer Institute determined that MRI-based prediction models can help reduce unnecessary biopsies in suspected prostate cancer patients and help improve personalized risk stratification.
Results of a recent NRG Oncology study, NRG Oncology/RTOG 0126, show that high-dose radiotherapy did not improve survival for men with intermediate-risk prostate cancer but did improve biochemical control and rates of distant metastases, when compared to standard radiotherapy.
Researchers at the University of São Paulo's Medical School in Brazil used magnetic resonance imaging to complete the first study conducted in Latin America to investigate brain volumes in transgender individuals.
Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided.
An Italian study featured in the March issue of The Journal of Nuclear Medicine demonstrates that a novel nuclear medicine imaging agent targeting copper accumulation in tumors can detect prostate cancer recurrence early in patients with biochemical relapse (rising prostate-specific antigen [PSA] level).
Seeing prices and calorie counts on a restaurant menu allows consumers to make better choices when eating out. In the same way, physicians make better choices when presented with the financial cost and potential risks of medications, labs and radiology tests when inside the electronic medical record making treatment decisions.
Researchers from the UCLA School of Nursing examined clinical records and magnetic resonance imaging brain scans of patients who were recently diagnosed with sleep apnea, and discovered several apparent connections between thinning of the brain's cerebral cortex and apnea symptoms.
Patients who receive cardiac positron emission testing imaging instead of single photon emission computed tomography scan experienced a significant increase in the detection of severe obstructive coronary artery disease, according to researchers at the Intermountain Medical Center Heart Institute in Salt Lake City.
An 84 year old was complaining of repeatedly losing his balance and falling over. He visited his primary physician in Northern Ireland from where he was referred to the emergency room. On MRI, the team of doctors found a 3½-inch pocket of air in his brain. This has never been reported before in any case and thus the detailed report titled, “The man that lost (part of) his mind,” was published in the journal BMJ Case Reports.
To uncover connections between brain regions and specific cognitive functions, neuroscientists have long made extensive use of techniques like functional resonance imaging (fMRI). First introduced in the 1990's, the method allows tracking the brain's activity while a test subject performs a task or responds to stimuli in the MRI scanner.
Choline intake during pregnancy can influence infant metabolism and brain development, according to a series of studies from the University of Illinois. Although the role of choline in neurodevelopment has been studied before in rodents, the new research, done with pigs, has more relevance to humans.
Tumor cells circulating throughout the body in blood vessels have long been feared as harbingers of metastasizing cancer - even though most free-floating cancer cells will not go on to establish a new tumor.
By peering at the brains of study subjects prompted to suppress negative emotions, scientists have gained new insights into how emotional regulation influences negative feelings and memories. The researchers hope the findings will lead to new methods to combat depression.
As we get older, it's not uncommon to experience "senior moments," in which we forget where we parked our car or call our children by the wrong names. And we may wonder: Are these memory lapses a normal part of aging, or do they signal the early stages of a severe disorder such as Alzheimer's disease? Currently, there's no good way to tell.
A new approach to analyzing prostate gland tissue may help address a major challenge in treating prostate cancer - determining which tumors are unlikely to progress and which could be life threatening and require treatment.
AMRA, the international leader in body composition analysis, and Siemens Healthineers have announced a new agreement that will see AMRA’s cloud-based, body composition analysis integrated into Siemens Healthineers Digital Ecosystem.
The psychiatric symptoms of NMDA receptor encephalitis are often not identified as a feature of this condition early on. The diagnosis of anti-NMDAR encephalitis utilizes history, examination, and specific assays.
