 - Needles

Using a lean flank steak embedded with simulated anatomic obstacles, researchers have demonstrated the superiority of a steerable needle over a straight one in percutaneous CT-guided needle biopsy, according to a study published online April 26 in the Journal of Computer Assisted Tomography.

 - TBxRay

After training two deep-learning models to identify tuberculosis, researchers at Thomas Jefferson University in Philadelphia have gotten their human-free method to nail the disease with 96 percent accuracy, according to a study published online in Radiology.

 - Cutting

It’s not news that Medicare has saved itself a ton of money on spending for medical imaging since the enactment of the Deficit Reduction Act of 2005. But now there are numbers to quantify the hurting the cuts have laid on radiologists and cardiologists—who’ve taken it on the chin even more.

 - NeuroAging

U.K. and Aussie researchers have introduced a clinically relevant neuroimaging biomarker of aging-related brain deterioration and, in the process, shown how brain age predicts mortality.  

 - Laser3

Researchers at Pohang University in South Korea have demonstrated a three-modality method of fusion imaging that uses a photoacoustic component to deliver high-resolution visualization, suggesting the potential to supply comprehensive image guidance in real time during various surgeries.

 - TraumaBay

Subpar quality in trauma CT images acquired in non-trauma care settings hampers accurate radiological interpretation, suggesting that other-than-imaging assessments are best until these patients are sent to trauma centers, according to a study published online April 18 in the Journal of Trauma and Acute Care Surgery.

Want to save a kidney patient from undergoing cancer surgery he or she doesn’t really need? Add a little sestamibi SPECT/CT imaging, suggest Johns Hopkins researchers.

 - TeenTude

New neuroimaging-based research at the University of Southern California has shown how, over time, the developing pubescent brain changes in distinct ways between boys and girls. 

University of Texas researchers have come up with a new chemical sensor that may lead to more cost-effective use of nuclear magnetic resonance (NMR) spectroscopy in both clinical and research settings. 

 - Cardio11

Compared side-by-side with standard cardiac CT for calcium scoring, ultralow-dose CT shows good sensitivity, specificity and overall accuracy despite its markedly lower radiation dose. In fact, it’s unlikely to miss coronary calcification in patients with at least moderate calcium load and could offer a sensible alternative for some patients sent for coronary CT angiography.
