Diagnostic Imaging

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.

Nearly half of CT scans ordered for patients presenting with dental infections are unnecessary, according to work published in the Journal of Oral and Maxillofacial Surgery, exposing patients to excess costs and physical risk where a more low-impact exam would have been sufficient.

A preliminary study published in Academic Radiology March 15 suggests dynamic contrast-enhanced MRI (DCE-MRI) can add value to the diagnosis of acute pancreatitis (AP) while subverting the use of perfusion CT, potentially paving the way for more irradiation-free analysis.

Over a recent eight-month period, children were not often called back to the ER of an academic children’s hospital in California due to discrepant radiology reports. However, the few who had to go back for a second look rang up additional charges to the tune of an average $2,289 per patient.

To cut respiratory motion artifacts on liver MRI, have patients hold their breath at the end of an exhale rather at the end of an inhale. That’s the recommendation of Stanford researchers after testing and comparing the two techniques, and it holds for unenhanced and contrast-enhanced scans.

Kinematic quantitative 4D CT can help differentiate patients with subtalar joint stiffness and chronic ankle instability, reported authors of a March 5 study published in the European Journal of Radiology. The technique may better personalize care for patients with ankle joint pain.

The research team also found combining 4D CT and technetium-99m sestamibi SPECT/CT did not improve diagnostic performance compared to 4D CT alone.

A screen-printed 12-channel pediatric MRI coil produced images with comparable quality and similar signal-to-noise ratio as those produced by a traditional 32-channel coil. Pediatric patients and their providers preferred the screen-printed coil for its flexibility and comfort.
