Diagnostic Imaging

“Given that health care systems are limited in their financial resources, competing surveillance strategies should be analyzed for their cost-effectiveness," wrote Paulo Henrique Lima and colleagues, in an April 17 study published in the American Journal of Roentgenology.

Some children in isolated villages have never seen an ultrasound machine, nevermind a portable one. A recent New York Times article provided an in-depth look at how impactful low-cost scanning technology can be to regions that don’t have access to basic imaging modalities.

CT colonography (CTC) achieved a similar positive predictive value (PPV) as colonoscopy during colon cancer screening and can help clinicians care for patients by specifying the nature of exam findings, according to a new study published in the American Journal of Roentgenology.

Rectal cancer patients given a “good prognosis” on MRI may be able to avoid preoperative chemoradiotherapy (CRT), a technique commonly associated with long-term adverse outcomes, according to results of a new study published in JAMA Oncology.

Combining digital breast tomosynthesis (DBT) with digital mammography (DM) can spot additional lesions in patients with breast cancer, reported authors of a recent study published in Radiology. However, the combined method did have limitations.

High-strength 7T MRI can better track cortical brain lesions and play a crucial role in evaluating the progression of multiple sclerosis (MS), but some experts aren't sure it is clinically feasible.

Clinicians can use optical coherence tomography angiography (OCTA) to noninvasively diagnose patients with early cognitive impairment, an early indicator of Alzheimer’s disease (AD), reported authors of a single-center study published in PLOS One.

Intraoperative MRI can be a cost-effective method for treating patients with high-grade gliomas, according to results of a microsimulation model study published in Radiology.

A study published in Radiology on March 26 suggests rapid short-pulse ultrasound is as effective—and maybe more so—than standard and long-pulse therapy for delivering drugs across the blood-brain barrier.

Researchers have established normal ranges of bone density in a part of the lumbar spine that is routinely imaged incidentally. Their primary aim is to equip radiologists with data that can be referred to when reading chest and abdominal CTs so the reader can opportunistically cross-screen for osteoporosis and check for compression fractures.

Clinical decision support (CDS) tools help trainee physicians in the emergency department order advanced imaging more appropriately. Then again, experienced physicians using the tools hit about the same appropriateness scores as the interns, residents and fellows.

Four years ago the U.K.’s Royal College of Radiologists released its evidence-based “iRefer” guidelines to help referring physicians in Ireland order the right imaging at the right time for the right indication. Now researchers on the Emerald Isle have compared the appropriateness of imaging ordered before and after the release, with an eye on economic costs as well as radiation doses.
