Training advised to plug lung cancer care gaps

Guideline-consistent care for patients with suspected lung cancer with mediastinal lymphadenopathy without distant metastases varies by region and physician characteristics, say researchers.

18F-FDOPA imaging can help distinguish radiation-induced lesions in patients with brain metastases

Imaging with the molecular imaging tracer 18F-FDOPA can help distinguish radiation-induced lesions from new tumor growth in patients who have been treated with radiation for brain metastases, according to new research published in The Journal of Nuclear Medicine. Using this amino acid tracer, researchers found that physicians could accurately differentiate the two types of lesions 83 percent of the time. Progression-free survival could also be predicted through evaluating the 18F-FDOPA imaging results.

Researchers found that blood vessels in face transplant recipients reorganize themselves

For the first time, researchers have found that the blood vessels in face transplant recipients reorganize themselves, leading to an understanding of the biologic changes that happen after full face transplantation.

Reimbursement cuts for image-guided breast biopsies may reduce women's access to mammography

Drastic reimbursement cuts for image-guided breast biopsies, and other medical imaging techniques in the 2014 Medicare Fee Schedule Final Rule, may further reduce women's access to mammography and other breast cancer services. The Centers for Medicare and Medicaid Services directly cut imaging reimbursement every year since 2007. This, along with 12 Medicare imaging cuts in the last six years due to legislation, increasingly threatens patient care.

Special issue of JACR focuses on the role of imaging-based screening in preventive medicine

To be published online Monday, Dec. 2, a special issue of the Journal of the American College of Radiology addresses imaging-based screening and radiology's increasing role in preventive medicine. Topics covered include breast density legislation, digital breast tomosynthesis (or 3-D mammography), lung cancer screening and computed tomography colonography reimbursement.

RSNA and Regenstrief Institute partner to standardize radiology procedure names

Under a contract awarded by the National Institute of Biomedical Imaging and Bioengineering, the developers of two advanced medical terminologies have begun work to harmonize and unify terms for radiology procedures. Creating standardized radiology procedure names will improve the quality, consistency and interoperability of radiology test results in electronic medical record systems and health information exchange.

Risk factors for Alzheimer's disease

Alzheimer's disease has joined cancer at the top of the list of feared diagnoses, and although Alzheimer's does have the potential to devastate millions of patients and families, there are reasons for hope - and possibly opportunities to reduce risk or alter the course of disease progression, according to Keith Black, MD, professor and chair of the Department of Neurosurgery at Cedars-Sinai.

Seed grants support cancer diagnosis and treatment, vascular health research

Five teams of scientists earned research seed grants awarded this year by the John S. Dunn Foundation. The awards support new collaborations by researchers at Rice University's BioScience Research Collaborative (BRC) and their partners at other institutional members of the Gulf Coast Consortia (GCC).

Neurosurgeons use novel technique to visualize the brain's delicate anatomy prior to surgery

Neurosurgeons at UC San Diego Health System are using a new approach to visualize the brain's delicate anatomy prior to surgery. The novel technique allows neurosurgeons to see the brain's nerve connections thus preserving and protecting critical functions such as vision, speech and memory. No needles, dyes or chemicals are needed to create the radiology scan. The main imaging ingredient? Water.

Findings could potentially save millions of people from having unnecessary cardiac catheterization

An ultrafast, 320-detector computed tomography scanner that shows both anatomy within coronary arteries and blood flow can accurately sort out which people need - or don't need - an invasive procedure to identify coronary blockages, according to an international study. The researchers say their findings could potentially save millions of people worldwide from having an unnecessary cardiac catheterization.

Data from CT scans can be used with 3-D printers to make accurate copies of fossilized bones

Data from computed tomography (CT) scans can be used with three-dimensional (3-D) printers to make accurate copies of fossilized bones, according to new research published online in the journal Radiology.

Brain signals in fibromyalgia patients: an interview with Dr. Marco Loggia from Massachusetts General Hospital and Harvard Medical School in Boston

Fibromyalgia patients suffer from a variety of symptoms, including widespread body pain and myofascial tenderness. They are ‘hyperalgesic’, which means that if you give them a stimulus that in healthy subjects is just mildly painful (or even completely innocuous), they may perceive it as excruciatingly painful.

Researchers determine link of CAC volume and CAC density with cardiovascular disease

Michael H. Criqui, M.D., M.P.H., of the University of California, San Diego, and colleagues determined the independent associations of coronary artery calcium (CAC) volume and CAC density with cardiovascular disease events.

Research findings offer new hope for millions of traumatic brain injury patients

Every year, nearly two million people in the United States suffer traumatic brain injury (TBI), the leading cause of brain damage and permanent disabilities that include motor dysfunction, psychological disorders, and memory loss. Current rehabilitation programs help patients but often achieve limited success.

Measuring BMI can help predict diabetic patient's risk for heart disease

Researchers from the Intermountain Medical Center Heart Institute, in collaboration with researchers from Johns Hopkins University and the National Institutes of Health, have discovered a simple way to further predict a diabetic patient's risk for heart disease: by measuring their body mass index or BMI.

LLN spirometry inadequate to detect airflow obstruction

Research published in Thorax indicates that use of a lower limit of normal spirometric threshold fails to identify a number of patients with airflow obstruction and chronic obstructive pulmonary disease.

Svelte completes enrollment in drug-eluting coronary stent Integrated Delivery System study

Svelte Medical Systems today announced enrollment of the final patient in the DIRECT II (Direct Implantation of Rapamycin-Eluting stents with bioabsorbable drug Carrier Technology) clinical study. DIRECT II is a prospective, randomized study comparing the safety and efficacy of the Svelte drug-eluting coronary stent Integrated Delivery System (IDS) to the Medtronic Resolute Integrity drug-eluting stent in 159 patients at 19 investigative sites.

Researchers study link between vision loss and Alzheimer's disease

An international team of researchers studying the link between vision loss and Alzheimer's disease report that the loss of a particular layer of retinal cells not previously investigated may reveal the disease's presence and provide a new way to track disease progression.

Study explains why south Asians have high susceptibility to developing type 2 diabetes

Lower amounts of brown adipose tissue (BAT, or ‘brown fat’) could help explain why south Asians—who make up a fifth of the world’s population—have an exceptionally high susceptibility to developing metabolic problems such as obesity and type 2 diabetes.
