Virtual reality at SIR 2018
Virtual reality was showcased at the annual scientific meeting of the Society of Interventional Radiology (SIR) held March 17-22 in Los Angeles. One study conducted at Stanford University Medical Center to evaluate the clinical utility of augmented virtual reality images showed that these were superior to images created by standard volume-rendering software with respect to surgical planning to repair splenic artery aneurysms. Also, the first virtual reality 360 training video showing an interventional radiology procedure, a special project of the Journal of Vascular and Interventional Radiology (JVIR), made its debut.

How to avoid sedating neonates for imaging procedures
Sedating newborn infants under 28 days of age for clinically necessary imaging can be a health risk. An article in the April issue of Pediatric Radiology describes risks associated with sedation and provides recommendations for non-sedated imaging of pre-term and term neonates.

Eliminating planar bone scans in the staging of asymptomatic BC patients with suspected metastases
Do planar bone scans offer clinical utility if a breast cancer patient has a computed tomography scan of the chest, abdomen, and pelvis performed to identify metastases? A study from Great Britain published in the January/February issue of the Journal of Computer Assisted Tomography suggests not.

Pseudotumor frequency from metal-on-metal total hip arthroscopy
Pseudotumors, the occurrence of cystic and/or solid masses in periprosthetic tissue, are a well-known complication of metal-on-metal total hip arthroscopy. The imaging examination of choice to identify these pseudotumors is a MR scan with metal artifact-reducing sequences. While conducting a study to evaluate MRI pseudotumor grading systems, researchers from The Netherlands determined that 43% of an asymptomatic control group of patients had pseudotumors, as well as 59% of high risk patients.

SIR 2018: Percutaneous CT-guided cryoablation for weight reduction
Losing weight may be possible with a percutaneous CT-guided cryoablation, a new weight-loss procedure designed for mild-to-moderately obese individuals being tested at Emory University School of Medicine in Atlanta. Attendees at SIR 2018 learned that 10 individuals participating in a pilot study lost weight and reduced their excess body mass over 90 days.

SIR 2018: GAE reduces pain and disability from knee osteoarthritis
Geniculate artery embolization (GAE) is a new procedure performed to reduce pain, stiffness, and difficulty performing daily activities caused by knee osteoarthritis. This minimally invasive, image-guided treatment blocks key arteries in the knee to reduce inflammation and pain. Interim results presented at SIR 2018 indicate that GAE may have a significant impact in the treatment of osteoarthritis pain as a whole, offering an alternative to joint injections and/or pain medications.

Diagnosing focal pancreatitis from pancreatic carcinoma with CEUS
Differentiating focal pancreatitis from pancreatic carcinoma on ultrasound imaging can be challenging. Focal pancreatic lesions caused by chronic pancreatitis are tumorlike and may often be confused with pancreatic carcinoma. In China, conventional ultrasound is frequently the first imaging examination performed to diagnose pancreatic lesions. Radiologists from the Peking University Cancer Hospital and Institute in Beijing report that contrast-enhanced ultrasound (CEUS) greatly increases the diagnostic accuracy over conventional ultrasound in an article published in the March issue of the Journal of Ultrasound in Medicine.
