Care Optimization

 

The evidence points to ergonomically incorrect elements that can bring on or worsen aches and pains.

Musculoskeletal ultrasound (MSK US) is being used more and more outside of radiology, according to a new study published in the Journal of the American College of Radiology.

An abscess is one of the few breast-specific emergencies that require urgent treatment in emergency departments (EDs). A new study, presented at RSNA 2017 in Chicago, found that ED environments generate unnecessary exams in addition to some that incompletely identify malignancies.

Discussion about the safety of using gadolinium-based contrast agents (GBCAs) in medical imaging has increased in recent years as a result of the element being found in patients’ brains following MRIs. In a new study presented Wednesday at RSNA 2017 in Chicago, however, researchers found no evidence of harm from the gadolinium being retained.

The Radiological Society of North America (RSNA) is once again gearing up for its annual meeting at McCormick Place in the beautiful city of Chicago. What does RSNA have in store for attendees this year? Richard L. Ehman, MD, president of the RSNA Board of Directors, gave us a sneak peek. Ehman, a professor of radiology and Blanche R. & Richard J. Erlanger Professor of Medical Research at the Mayo Clinic in Rochester, Minn., previewed RSNA 2017 and reviewed some of the biggest issues affecting medical imaging today.

Fatigue in Radiology: What is its Impact and What Can Be Done?

A typical workday for today’s radiologist is probably anywhere from 10 to 12 hours a day, and in most settings, nearly all of those hours are spent reading images at a PACS workstation. This may be a good thing from a healthcare enterprise and business perspective, but what happens to a radiologist’s diagnostic performance after even just eight hours of clinical work? Is it the same as when they started first thing in the morning? Are residents impacted more or less by fatigue given their fluctuating work hours and the pressures of learning their craft? 

Stereotactic radiosurgery vs. whole-brain radiation for treating brain tumors

A new study led by researchers from the University of Missouri School of Medicine compared two common postsurgical therapies for metastatic brain tumors, the most common in adults, and found that stereotactic radiosurgery can provide improved outcomes for patients compared to whole-brain radiation.

Could a new contrast agent for MRI be on the horizon?

Massachusetts Institute of Technology (MIT) researchers developed a new specially coated iron oxide nanoparticle that could provide an alternative to conventional gadolinium-based contrast agents used for MRI procedures. Current gadolinium agents, have in rare cases, been found to create adverse effects in patients with impaired kidney function.

Less frequent follow-up after breast biopsies is acceptable

Minimally invasive breast biopsies have been regularly performed since the 1990s, affording women with suspicious findings a cheaper and less invasive diagnostic exam when compared to surgical biopsy. Even as most biopsies are benign, the potential for sampling error makes follow-up appointments an attractive option for reducing false-negatives.

Fighting the war on obesity with bariatric embolization

Preliminary results on bariatric embolization, a new interventional radiology technique for weight loss, suggest it has the potential to become a new tool in combatting obesity.

Radiologist becomes first in Miami to provide cryoablation for early stage breast cancer

Miami radiologist Michael Plaza, MD, is the first in Miami to use the Visica 2 Treatment System, a cryoablation device, to treat early stage breast cancer. The device destroys the tumor by freezing and damaging the adjacent vasculature that fuels tumor growth.

How to halve your mammography recall rate: Baylor Radiology’s resounding success

A group of faculty and staff from the Baylor College of Medicine’s Department of Radiology implemented a quality improvement project, intending to make the screening program faster and more accurate. Their four-step program generated conclusive improvements in recall rates and shortened the time between screening and treatment, and they published their results in the Journal of the American College of Radiology.

Researchers find variations in lung cancer screening practices

With deaths from lung cancer at an all-time high, a team of researchers looked at recommended guidelines for lung cancer screening, referral patterns and patient tracking methods in various CT facilities in North Carolina.

Botched contrast uptake? Try post-processing—that should fix it right up

A German-Belgian group of researchers used post-processing tools to reduce repeat imaging when diagnosing pulmonary embolism, publishing their research in the February issue of Academic Radiology.

Can fMRI scans done prior to antidepressant therapy be beneficial?

Researchers at the University of Illinois at Chicago and the University of Michigan conducted a study with data suggesting that a functional MRI brain scan may be beneficial for patients being considered for antidepressant therapy.
