The Church Street Site of Humber River Regional Hospital, Weston, Ontario, has recently improved its diagnostic imaging services following the implementation of a new MRI system in the facility.
The new MRI unit is the second for Humber River Regional Hospital. It is going to permit the hospital to perform more than 3000 scans annually. The new system was added to the facility aiming to reduce waiting time for patients who are in need on an MRI scan.
Moreover, River Regional Hospital is going to get an immediate one-time investment of $235,600 to aid the facility in performing about 1400 other MRI scans using the currently used unit. The implementation of the new MRI system represents a part of the Open Ontario Plan, carried out by the government, to improve the access to healthcare for patients.

CT Scans Help In Abdominal Pain Diagnosis In Emergency Departments, Study
According to a recent study, using Computed Tomography (CT) scans can significantly aid doctors in diagnosing the causes of abdominal pain in emergency departments more accurately and rapidly. The study took place at Massachusetts General Hospital (MGH), and its findings are highlighted in the February issue of the American Journal of Roentgenology.
Researchers mentioned that abdominal CT scans offered details that resulted in changing the plan of treatment of nearly 50% of the participating patients in the study, and the scans also helped in reducing the number of hospital admissions. Scott Gazelle, MD, MPH, PhD, an MGH radiologist and director of the Institute for Technology Assessment, senior author of the study, explained "Our report addresses an important question with substantial policy relevance – what is the value of CT scanning in the emergency department setting? We specifically looked at how the use of CT for patients with abdominal pain affects physicians' thinking about their patients' diagnosis, their confidence in the diagnosis and the treatment plan; and we found that it significantly affected all three."
Dr. Gazelle mentioned that studies have been taking place on medical imaging in order to design new methods for reducing healthcare costs. He said "We've strongly believed that the use of CT in the emergency department can improve efficiency in the workup for many conditions, but we haven't had the evidence we would like to back up that assertion. We chose abdominal pain for our study because it's a common presenting symptom that doesn't have the clearly defined diagnostic guidelines available for other common symptoms that can lead to CT, like headache."

A New XFELs Technology To Measure The Structure Of Membrane Proteins
new method has been created by the Australian researchers in order to measure the structure of membrane proteins despite being damaged when using X-ray free-electron lasers (XFELs), that discovery will aid in tracking the improvement of targeted drugs using new XFELs technology.
Today, about 70% of drugs in the market rely on the activity of membrane proteins, which are complex molecules that form the membranes of the cells in our body. The main problem for the design of new pharmaceuticals, often defined as “membrane protein problem,” is because they do not form the crystals necessary to enable further investigation of the structure to design better drugs.

South Lincoln Medical Center to Offer Digital Mammography
Thanks to the Helmsley Charitable Trust, South Lincoln Medical Center (SLMC), Kemmerer, WY, is on the way to have digital mammography service provided through its facility. SLMC lately received a fund from the Leona M. and Harry B. Helmsley Charitable Trust.
The fund will be used to promote SLMC’s mammography service. A new state-of-art digital mammography unit will be acquired, in addition to upgrading radiology workstations, mammography room and the changing area of patients. Robert Berlin, M.D., Staff Radiologist, SLMC, said "This acquisition is a major enhancement to the services that we offer our patients. Although the new equipment will have a similar appearance to the patient, the quality of the examinations will be superior, with increased sensitivity and decreased radiation dose."
Digital mammography generates significantly clearer images of the breast tissue. The images can be magnified or enhanced, which results in promoting the abilities to identify breast abnormalities, especially breast cancer, much earlier, where the condition can be treated more effectively.

PET scan with F-18 moves closer to FDA approval of Alzheimer’s diagnostic test
By Michael O'Leary:
The presence of beta-amyloid plaques shown on PET brain scans using the imaging agent florbetapir correlated with autopsy confirmed Alzheimer’s disease 96 percent of the time, a study appearing in today’s Journal of the American Medical Association (JAMA) shows.
Led by Dr. Christopher Clark of Avid Radiopharmaceuticals, the study moves the Philadelphia company a step closer to approval for a diagnostic test for Alzheimer’s, which currently often isn’t confirmed in patients until after death.
According to background information in the study, diagnosing Alzheimer’s as distinct from other forms of cognitive decline is imprecise at best. Between 10 percent and 20 percent of patients diagnosed with Alzheimer’s are found not to have had the disease following autopsy exam of brain tissues. Another 33 percent of patients with mild signs and symptoms are found to have had undiagnosed Alzheimer’s following autopsy.
“Both diagnosis and treatment of Alzheimer’s disease are hampered by the lack of noninvasive biomarkers of the underlying pathology,” the authors wrote. “The ability to identify and quantify brain beta-amyloid could increase the accuracy of a clinical diagnosis of Alzheimer’s disease."

New Mexico Software Launches Full-Function iPad App for its PACS system
By Michael O’Leary
It is not often a company executive has the chance to conduct a real-life test of his company’s products, but New Mexico Software CEO Richard Govatski did just that over this past holiday season. Having slipped getting into his hot tub he twisted his knee, and of course being the holiday, found himself at an urgent care clinic in Albuquerque testing the company’s new iPad app for its PACS.
“The doctor took X-rays of my knee, sent them to XR-EXpress, where they were read by a physician in Los Angeles who then sent the report back to the XR-EXpress,” Govatski told The Hub. “The attending physician then accessed the images and radiologist’s report from his iPad and was able to show me a knee spur that could be causing the pain, and suggested I have an MRI to see if there was any soft-tissue damage.”
It is a scenario that Govatski thinks will become more and more common as the explosion of tablet devices announced at the recent Consumer Electronics Show accelerates the convergence of Internet and mobile computing.

Display Requirements for Radiology and Use of Commercial Grade Monitors
It is not uncommon for me to walk into an ER or ICU and find physicians using a commercial grade monitor that is obviously not calibrated and does not have the required contrast range needed to make a proper diagnosis. This is a major potential liability and could impact patient wellness if critical decisions are made based on viewing images of hairline fractures or a potential pneumo-thorax on these monitors.
This is not to say that one ought not use commercial grade monitors for clinical review, rather, if used for diagnostic purposes, one needs to make sure that they are properly calibrated and meet the requirements for diagnostic viewing. The question is, what are these requirements?
There are actually two sets of guidelines, one from the American College of Radiology (ACR) and one from the American Association of Physicists in Medicine (AAPM). Unfortunately, each group’s guidelines are slightly different, hard to interpret, and leave out some basic requirements such as stability and the capability for calibration and the requirement for accessing the calibration information. The latter is critical from a liability perspective.
As an example of the latter, I recently talked with a PACS administrator who was required to show the calibration records of a particular monitor that was used three years ago for a diagnosis that was later questioned in court. He had to prove that the monitor was within calibration at that time. Another example where the access to calibration data might be important is when the reading is done at a remote site, which does not have a person responsible for the image quality and integrity, so that the proper calibration can be verified and managed remotely.

Imaging Advances And Proper Displays Are Needed For Accuracy
By Michael O'Leary:
At the center of the continuing controversy over mammograms is the potential that too frequent screening will produce too many unneeded biopsies and surgeries. As with all imaging technologies, however, mammography technology continues to advance. This issue of the Health Imaging Hub newsletter carries two stories about research advances that continue to improve the value of imaging tools for clinical practice.
The report, “Density of Mammographic Masses are a Significant Predictor of Cancer”on a research study that shows that the long suspected, but often-underutilized descriptor of suspicious lumps, may be more useful than thought. Dr. Ryan Woods and colleagues at the University of Wisconsin found that of 118 malignant lesions biopsied, 70.2 percent were high-density masses compared to 22.3 percent of the isodense or low-density masses. While it is an incremental advance, Woods points out that, “We know that mammograms are the best screening tool we have for finding cancer early, so anything we can do to improve diagnostic accuracy is useful.”
At the same time, in the article, “Advance Makes Real-time Imaging of Cellular Processes Possible” an imaging advance that may some day allow doctors to see disease processes in real time promises to improve treatments as doctors will be able to see at the cellular level whether treatments are working, or even necessary as immune cells mount a response to injury or disease.
Reporting in the journal Nature Methods, a research team led by Dr. Max Krummel, associate professor of Pathology at UCSF, has developed a new imaging technique that allows researchers to observe cellular interactions in real time without disrupting normal function. In their study they showed a series of events in an immune response to lung injury in mice. The advance overcomes the problem of blurred images produced by conventional means and results in clear images of cells interacting. A stunning series of videos are posted online in supplementary materials created by Dr. Mark R. Looney, co-first author and assistant professor in Medicine and Laboratory Medicine at UCSF.
While the clinical application of the technology is a long way off, Looney says it could soon be applied to lung biopsies. For now, Krummel says the research application could potentially lead to significant advances in understanding how cells are organized and deployed.
