Plasmin Delivered Through A Bubble Is More Effective Than TPA In Busting Clots
A new study from the University of Cincinnati (UC) College of Medicine has found that, when delivered via ultrasound, the natural enzyme plasmin is more effective at dissolving stroke-causing clots than the standard of care, recombinant tissue plasminogen activator (rt-PA)...
MRI Useful For Predicting Failure Of Metal-On-Metal Hip Implants Before Symptoms Appear
Metal-on-metal hip implants can cause inflammation of the joint lining (synovitis) long before symptoms appear, and magnetic resonance imaging (MRI) can be used to identify this inflammation, according to a new study by researchers at Hospital for Special Surgery...
MRI Autopsies Offer A New Option To Traditional Methods
Autopsies that are minimally invasive by method of MRI scans and other techniques like blood tests can determine the cause of death in babies and fetuses just as accurately as conventional autopsies...
Diagnosic Technology Improved By Chemistry Breakthrough
From microscopes to MRI scanners, imaging technology is growing ever more vital in the world's hospitals, whether for the diagnosis of illness or for research into new cures. Imaging technology requires dyes or contrast agents of some sort. Current contrast agents and dyes are expensive, difficult to work with and far from ideal...
Tickling Laughter Produces Different Brain Response To Social Laughter
When we hear someone laughing because they are being tickled, the connections in our brains respond differently to when we hear social laughter, such as that which expresses joy or accompanies mocking behavior...
Lantheus Medical Imaging To Proceed With Flurpiridaz F 18 Phase 3 Clinical Program Based On Interim Analysis Of Data From First Phase 3 Study
Lantheus Medical Imaging, Inc., a global leader in developing, manufacturing and distributing innovative diagnostic imaging agents, today announced an important milestone for its Phase 3 flurpiridaz F 18 clinical program. An interim analysis of the first of two Phase 3 studies has met the criteria for completion...
Method Devised For Enhancing Chemical Exchange Saturation Transfer MRI
Researchers at New York University and NYU Langone Medical Center have created a novel way to enhance MRI by reducing interference from large macromolecules that can often obscure images generated by current chemical exchange saturation transfer (CEST) methods...
New Imaging Technology Could Reveal Cellular Secrets
Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor...
Using Microbubbles To Improve Cancer Therapy
Microbubbles decrease the time and acoustic power of ultrasound required to heat and destroy an embedded target, finds research in BioMed Central's open access journal Journal of Therapeutic Ultrasound. If these results can be replicated in the clinic, microbubbles could improve the efficiency of high intensity ultrasound treatment of solid tumors...
For Intravascular Ultrasound-Guided Inferior Vena Cava Filter Placement, 2 Venous Punctures Not Always Needed
One venous puncture, rather than two, is a safe and effective approach to intravascular ultrasound-guided inferior vena cava filter placement in critically-ill patients, a new study shows. Inferior vena cava filter placement is done to prevent or treat pulmonary emboli or deep venous thrombosis...
Renal Cell Tumors More Likely To Metastasize Better Identified By Chemical Shift MRI
Adding "chemical shift" techniques to MRI can help differentiate clear cell renal cell carcinoma from other types of renal cell cancer, a new study shows. That differentiation can help physicians better determine treatment for these patients. The study, conducted at Massachusetts General Hospital in Boston, included 156 patients with proven renal cell cancer...
In Women With Dense Breasts, Screening Breast Ultrasound Detects Cancers Missed On Mammography
Screening breast ultrasound performed after mammography on women with greater than 50% breast density detects an additional 3.4 cancers or high risk lesions per one thousand woman screened, a detection rate just under that of screening mammography alone for women with less dense breasts, a new study shows. Screening mammography detects 4-5 cancers per thousand women screened...
Expanding Obstetric And Breast Imaging Programs In Underserved Area Of Uganda
Radiologists are a step closer to implementing a program in an underserved region of Uganda for diagnosing and treating women with palpable breast masses. The program combines a unique diagnostic algorithm along with targeted community outreach, said medical student Chris Duncan working with the organization Imaging the World...
Brain Scan Offers First Objective Measure Of Pain
Using fMRI scans of the brain, US scientists have for the first time developed a method of "seeing" pain and suggest it may lead to reliable ways for doctors to quantify objectively how much pain patients are feeling. They also propose their study may open the route to using brain scans to measure anxiety, depression, and emotional states like anger...
'Fast fMRI' Protocol Could Aid In Planning Surgery For Epilepsy And Brain Tumors
A new functional magnetic resonance imaging (fMRI) technique may provide neurosurgeons with a non-invasive tool to help in mapping critical areas of the brain before surgery, reports a study in the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health...
Dangerous Plaque May Be Detected By MRI Measure Of Blood Flow Over Atherosclerotic Plaque
Researchers from Boston University School of Medicine (BUSM) have shown that using magnetic resonance imaging (MRI) to measure blood flow over atherosclerotic plaques could help identify plaques at risk for thrombosis...
Computer Can "See" Our Dreams
fMRI scans can reveal the visual images we have in our brains while we are dreaming, researchers from Japan reported in the journal Science. Put simply, they have found a way of seeing our dreams...
Migraine Patients Have Brain Abnormalities, MRI Scans Show
Patients who suffer from migraines have reduced cortical thickness and surface area in pain-processing regions of the brain, compared to individuals who never have migraines, Italian researchers revealed. They explained in the journal Radiology that brain abnormalities in migraine sufferers may be either present at birth, or develop over time...
FDA Approves Dotarem® (Gadoterate Meglumine), First Macrocyclic And Ionic Gadolinium-Based Contrast Agent In USA
Guerbet have announced that the US Food and Drug Administration (FDA) has approved Dotarem® (gadoterate meglumine), a gadolinium-based contrast agent (GBCA) indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (2 years of age and older) to detect and visualize areas with d...
In Metal-On-Metal Hip Replacement, MRI May Predict Adverse Tissue Reaction
Magnetic Resonance Imaging (MRI) can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Early detection can result in timely revision surgery, decreasing the risk for further tissue damage and pain...
