3-T MRI advancing on ultrasound for imaging fetal abnormalities

Does higher field strength increase risk?

2015-04-20
(Press-News.org) TORONTO, April 20, 2015--Although ultrasound remains the primary imaging modality used in prenatal imaging, fetal MRI is playing an increasing role in further evaluation of fetuses suspected of congenital anomalies. As 3-T MRI scanners become more common due to their improved image signal-to-noise ratio and anatomical detail, the benefits of 3-T MRI must be weighed against potential risks to the fetus that may result from the higher field strength.

"MRI is playing an increasingly important role in the assessment of complex prenatal disease," said Kathleen E. Carey, MD, Mayo Clinic, Jacksonville, FL. "The use of stronger 3-T field strengths may allow for improved visualization of subcutaneous fat and osseous structures, including the hands and feet of the developing fetus."

The study is featured in an electronic exhibit at the ARRS 2015 Annual Meeting in Toronto.

Advanced techniques improve success rate of IVC filter removal to more than 98 percent

2015-04-20
TORONTO, April 20, 2015--The design of inferior vena cava (IVC) filters for pulmonary embolism prophylaxis, once used almost exclusively for permanent implantation, has progressed to retrievable designs. However, complications can create scenarios in which the routine filter retrieval is either extremely difficult or impossible. The use of advanced retrieval techniques, such as loop-snare, "sandwich," stiff wire or balloon realignment, forceps retrieval and excimer laser sheath can raise the overall success rate above 98%. "Implementation of IVC filters is increasing ...

Thin-cut coronary calcium quantification: Advantages compared with standard 3 mm slices

2015-04-20
TORONTO, April 20, 2015--Research comparing the accuracy of three MDCT slice thicknesses has found that 3-mm slices underestimated coronary artery calcium (CAC) scores at every level of calcification. The inaccuracies were caused by partial volume averaging errors. "Our analysis proved this concept and showed that CAC can be more accurately measured with 0.5 or 1 mm using isotropic data acquisition obtained by a volume scanner at identical radiation dose ," said Farhood Saremi, MD, University of Southern California. "Coronary artery calcium can be more accurately measured ...

Ultrasound/MRI fusion biopsy detects more sonographically occult prostate cancers

2015-04-20
TORONTO, April 20, 2015--Research conducted at the State University of New York Upstate Medical University has found that multiparametric MRI and subsequent fusion of MR images with ultrasound enables a targeted biopsy of high-suspicion foci with increased diagnostic accuracy of prostate cancer over established methods. For patients on active surveillance for low-risk cancer, multiparametric MRI can better characterize the prostate gland and find occult foci of higher grade disease. "The need to differentiate a clinically significant cancer from indolent cancers is ...

Computational fluid dynamics in coronary plaques predict coronary artery disease

2015-04-20
TORONTO, April 20, 2015-- Computational fluid dynamics (CFD) simulation based on 3D luminal reconstructions of the coronary artery tree can be used to analyze local flow fields and flow profiling resulting from changes in coronary artery geometry. Research conducted at Curtin University in Perth, Australia, used the technique to identify risk factors for development and progression of coronary artery disease. Both idealized and realistic coronary models were successfully generated using CFD simulations of hemodynamic flow. Results showed a direct correlation between left ...

Dual-energy CT imaging improves pancreatic cancer assessment

2015-04-20
TORONTO, April 20, 2015-- Dual-energy CT (DECT) has several potential applications in the detection, characterization, staging, and follow-up of pancreatic cancer patients, according to a new study conducted at Johns Hopkins University. "DECT imaging is a promising technique, and it has the potential to improve lesion detection and characterization beyond levels available with single-energy CT imaging," said Satomi Kawamoto, MD, associate professor of radiology and radiological science at Hopkins. Several studies have shown that DE CT can help assessment of pancreatic ...

New quality improvement system significantly reduces CT misadministration

2015-04-20
TORONTO, April 20, 2015--A protocol developed by radiologists at the Santa Clara Valley Medical Center reduced CT misadministration at the Santa Clara Valley Medical Center from 18 instances in 60,999 studies to zero in 36,608 in just 10 months. Misadministration includes, but is not limited to, imaging the wrong patient or body part without a physician's order or repeated imaging of a patient without a physician's order. The best practices protocol includes several levels of assessment, including reverification checklists, workflow clarification, and individual accountability. "CT ...

NFCR-supported scientists discover key factor in brain cancer resistance

2015-04-20
(Bethesda, MD, April 20, 2015) Researchers at the NFCR Center for Cancer System Informatics at MD Anderson Cancer Center have discovered a key factor that may explain drug resistance in glioblastoma (GBM), the most common and deadliest form of brain cancer. GBM accounts for 17% of all brain tumors, and over 10,000 new cases of GBM are diagnosed in the US each year. Unfortunately - since there are no effective, long-term therapies available - survival is typically less than 17 months. Approximately 50% of GBMs are known to have mutations in a gene called EGFR. However, ...

A cold cosmic mystery solved

A cold cosmic mystery solved
2015-04-20
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected. Now, a team of astronomers led by Dr. Istvan Szapudi of the Institute for Astronomy at the University of Hawaii at Manoa may have found an explanation for the existence of the Cold Spot, which Szapudi ...

Disney Research creates method enabling dialogue replacement for automated video redubbing

2015-04-20
A badly dubbed foreign film makes a viewer yearn for subtitles; even subtle discrepancies between words spoken and facial motion are easy to detect. That's less likely with a method developed by Disney Research that analyzes an actor's speech motions to literally put new words in his mouth. The researchers found that the facial movements an actor makes when saying "clean swatches," for instance, are the same as those for such phrases as "likes swats," "then swine," or "need no pots." Sarah Taylor and her colleagues at Disney Research Pittsburgh and the University of ...

The Lancet Infectious Diseases: Leading doctors warn that sepsis deaths will not be curbed without radical rethink of research strategy

2015-04-20
Leading doctors today [Monday 20 April, 2015] warn that medical and public recognition of sepsis--thought to contribute to between a third and a half of all hospital deaths--must improve if the number of deaths from this common and potentially life-threatening condition are to fall. In a new Commission, published in The Lancet Infectious Diseases, Professor Jonathan Cohen and colleagues outline the current state of research into this little-understood condition, and highlight priority areas for future investigation. Sepsis--sometimes misleadingly called "blood poisoning"--is ...
