Diagnostic Imaging

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.

Ultrasound scans of the calcaneus—or the heel bone—were equal to results gathered from dual-energy x-ray absorptiometry (DXA) for assessing bone health, according to new research published online in the March issue of The Journal of the American Osteopathic Association.  

“Our results may help in planning medical injury surveillance systems for future large-scale sports events tailored for each specific sport and may potentially aid in developing preventive efforts before and during competition,” wrote the authors of a Feb. 21 study published in Academic Radiology.

CT angiography (CTA) and transcranial Doppler (TCD) fall short in detecting cerebral vasospasm (CVS) and predicting delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH), reported authors of a recent study published in the inaugural edition of Critical Care Explorations.

A novel PET/CT imaging agent—18F-GP1—produced a high-quality image and yielded a high detection rate for diagnosing acute venous thromboembolism (VTE), reported researchers of a study featured in the February issue of The Journal of Nuclear Medicine.

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.
