US-guided needle tenotomy benefits tennis elbow
For patients with common extensor tendinosis of the elbow, physical therapy often resolves the pain and disability. But for those who need more help, an ultrasound-guided percutaneous technique is proving to be an effective alternative to surgery.

Coronary CTA requires dedication, 64-slice minimum
CHICAGO - Cardiac imaging may have slipped away from radiology in stages over the years, but radiologists can capture the boom in coronary CT angiography if they move fast, train hard, and plan to use at least a 64-slice scanner. Those were some of the views shared by leading practitioners during a lively and opinionated keynote and panel discussion Tuesday at the RSNA meeting.

Ultrasound
All specialties see more vascular US volume
CHICAGO - Unlike other imaging areas where American radiologists appear to be losing ground to other specialists, recent data on procedural volumes show that vascular ultrasound has been a "win" for radiology.

Preablation CTA may avoid complications
CHICAGO - As electrophysiologists perform more pulmonary vein isolation procedures to treat atrial fibrillation, preprocedural CT angiography may help avoid potentially fatal complications by showing anatomic variants and proximity of a vulnerable esophagus, according to a presentation Monday at RSNA 2005.

Ankle cartilage MRI improved by force
CHICAGO - Researchers have successfully used a noninvasive distraction device that helps separate the tibial and talar surfaces during imaging so that the cartilage of each can be more accurately assessed, according to a presentation Sunday at the RSNA meeting.

CEUS shows metastases' hypervascularity
CHICAGO - One piece of conventional wisdom has been overturned in a study using contrast-enhanced ultrasound (CEUS) that showed almost all hepatic metastases exhibit arterial hypervascularity, including those generally thought to be hypovascular.

CMS delays, reduces proposed Medicare imaging cuts
The U.S. government's proposal to cut Medicare technical reimbursement for contiguous imaging in both the hospital outpatient and physician office settings has been scaled back or delayed, with the American College of Radiology (ACR) taking credit for the turnabout.

Triage with chest x-ray expedites PE evaluation
Multidetector CT pulmonary angiography (CTPA) may be the best noninvasive exam for diagnosing pulmonary embolism (PE), but using it in every suspected case may not be desirable or even possible given the associated radiation burden and contrast risks. Now researchers are touting plain x-rays to determine who needs CTPA versus scintigraphy.

Figure: Improved image quality with a generative adversarial network architecture for low- to high-field-strength image translation, called LowGAN. (A–C) Top: High-field-strength (3-T) and low-field-strength (64-mT) images and LowGAN outputs for a single participant across (A) fluid-attenuated inversion recovery (FLAIR), (B) T1-weighted (T1w), and (C) T2-weighted (T2w) contrasts. Bottom: Graphs demonstrate the structural similarity index (SSIM), peak signal-to-noise ratio (PSNR), normalized cross-correlation (NCC), and feature similarity index (FSIM) between high field strength and low field strength (64-mT) and high field strength and LowGAN outputs. a.u. = arbitrary units.****p ≤ 0.0001.
