Elastography is attracting growing attention in prostate imaging. The term refers to the measurement of the elastic properties of tissues, based on the well-established principle that malignant tissue is harder than benign tissue. A color classification system registers tissue as benign (green) or malignant (blue).
Dutch hospital demonstrates repeatable accuracy of USPIO-based protocol on metastastic lesions
Most 3T MR systems are sold to university hospitals and research facilities, and relatively few go to private practices.
Parallel imaging and a 32-channel coil help modality gain the upper hand over FDG-PET/CT
The emerging therapy of islet transplantation has shown great promise for diabetes patients.
CONTEXT: Combining proton MR spectroscopic imaging, sodium MR, and PET/CT imaging may be an effective multimodality approach for detecting early response to chemotherapy in breast cancer patients, according to Dr. Michael Jacobs, a radiologist at Johns Hopkins School of Medicine.
Two top meetings showcase MI progress, while investment in basic sciences soars
Most benign lesions considered unspecific on ultrasound or CT can be identified with great confidence on MRI
The National Electrical Manufacturers Association has published four standards that are part of a series of test standards developed by the medical diagnostic imaging industry for the measurement of performance parameters, such as noise levels, energy deposition, and electric field strength, that govern image quality of MRI systems.
Most infected individuals remain asymptomatic carriers, but hepatosplenic form of schistosomiasis can be associated with serious complications
After 19 years in a minimally conscious state, a man recovered language and motor function. Diffusion tensor MR imaging showed reorganization of the patient’s brain white matter that could have facilitated functional recovery.
Diffusion tensor MR imaging, which depicts the displacement of water molecules through tissue, can visualize changes to ischemic brain white matter in infants at least two to three hours before conventional MRI can document changes, according to a study in the July issue of Radiology.
What music inspires a Nobel Laureate? The answer: Gustav Holst’s Jupiter from The Planets, Bedrich Smetena’s Ma Vlast (My Country), Charles Trenet’s La Mer, Perry Como’s Magic Moments, and William Walton’s Coronation March.
A computer model simulation suggests that adding breast MRI screening may be cost-effective for women of certain ages who carry BRCA1 and BRCA2 gene mutations, according to Stanford University researchers.
For the first time, a study has shown that a smaller corpus callosum in people with autism correlates with lower brain functional connectivity. The finding supports a new theory of cortical underconnectivity in autism. This theory proposes that autism is a cognitive and neurobiological disorder associated with underfunctioning of integrative circuitry.
Functional MRI data suggest that improper development of specific brain circuitries could beget bipolar disorder, according to National Institute of Mental Health researchers. Their findings underscore shifting beliefs regarding the origins of chronic psychiatric diseases.
Volumetric MR scanning can accurately track structural changes preceding the onset of autosomal dominant polycystic kidney disease, according to a study by the National Institute of Diabetes and Digestive and Kidney Diseases. MR could sound the alarm on disease progression earlier than standard blood and urine tests.
A new space shuttle mission reminds musculoskeletal specialists that astronauts share with bedridden patients a susceptibility to muscle and tendon atrophy. Phase-contrast cine MR at 3T provides a useful, accurate way to guide management of this atrophy, according to researchers at the University of California, Los Angeles.
Diffusion hyperpolarized helium-3 MRI could provide a noninvasive means to diagnose and manage children with bronchopulmonary dysplasia, according to a study presented at the 2006 International Society for Magnetic Resonance in Medicine meeting in May.
The California State Assembly has passed a bill that would restrict sales of ultrasound machines to medical professionals. The move follows public safety concerns raised by actor Tom Cruise's purchase of ultrasound equipment to perform exams on his pregnant fiancee in November 2005.
We all make mistakes, and some cost more than others. It seems that your brain has a special compartment set aside to absorb these moments.
A top official for the American College of Cardiology says cardiologists should drive quality improvements in cardiac imaging, and that a major effort should be made to increase how imaging is used in cardiology research and practice.
Parallel imaging continues to drive MRI development as an enabling technology for clinical 3T and as the catalyst for new data acquisition strategies offering unprecedented improvements in temporal resolution.
Time-of-flight PET/CT and PET/MR are adding sizzle to the PET equipment scene, with the driving motivation being fast, faster, and fastest data acquisition.
Prostate imaging can be a lonely, thankless line of work for radiologists. Specialists are scarce, and urologists have the upper hand. Cancer screening is controversial, and imaging research has yielded a mixed bag of results. Nevertheless, prostate guru Dr. Ethan Halpern is bullish about the future.
