3D vascular US: Quantifying early carotid and femoral atherosclerotic plaque burden
The ability to identify and quantify cardiovascular risk factors in asymptomatic middle-aged indi-viduals can be a life-saving opportunity to make lifestyle changes and obtain more timely treatment. Detection of subclinical atherosclerosis improves cardiovascular risk prediction, and two-dimensional vascular ultrasound is an imaging exam used for this purpose. Researchers in Spain report that 3D vascular ultrasound (3DVUS) is a safe and reproducible approach to detect and quantify early atherosclerotic burden in the carotid and femoral arteries.
Assessing renal capsule invasion with arterial spin labelling MRI
The staging of renal cell carcinoma (RCC) and assessing the prognosis of a patient relies on the tumor size and perinephric fat invasion seen on MRI. But for very small tumors, visualization and assessment of perinephric fat invasion may not be diagnostically feasible. Arterial spin labelling (ASL) is considered to be a promising technology to assess tumor perfusion in renal masses. A Chinese research team prospectively evaluated the performance of combining morphological and ASL MRI to detect pseudocapsule defects in RCC and to predict renal capsule invasion, and reported their findings in Clinical Radiology.
Congressional shooting victim Rep. Steve Scalise recounts life-saving role of IR in
A video has been posted on the Society of Interventional Radiology (SIR) website that interventional radiologists should know about: a panel discussion that includes Representative Steve Scalises comments about how interventional radiology procedures helped save his life. Scalise was gravely injured when shot in the hip on June 14, 2017 while practicing on a Little League baseball field in Alexandria, VA for the Democrat vs. Republican annual charity Congressional Baseball Game.
Potential of ultrasound tomography to measure breast density
Ultrasound tomography (UST) is a 3D whole-breast imaging technology that shows potential to become a radiation-free method of accurately measuring breast density in women of both pre-mammographic and screening age. It could eventually be used to stratify women to different breast cancer screening methods based on their breast density. British researchers reported their findings of a study to evaluate UST, comparing whole-breast volume averaged speed of sound (VASS) with percentage water density from non-contrast MR imaging.
MR-HIFU may be comparable to RFA for treatment of pediatric osteoid osteoma
Magnetic resonance imaging-guided high-intensity focused ultrasound (MR-HIFU) is a promising new treatment for osteoid osteoma, according to a study conducted at Childrens National Medical Center in Washington, D.C. Non-invasive and radiation-free, MR-HIFU has the potential to be an alternative treatment in lieu of radiofrequency ablation (RFA), the current standard for curative treatment for these patients.
Applying Quantitative CT Image Feature Analysis to Predict Ovarian Cancer Treatment Response
Women with ovarian cancer receiving chemotherapy to treat metastasized tumors respond very dif-ferently. Because of this, extensive research is being conducted worldwide to identify better methods for imaging modalities to more accurately predict and monitor treatment responses.
TMIST clinical trial comparing 2D and 3D mammography extends to United States
The Tomosynthesis Mammographic Imaging Screening Trial (TMIST), the first randomized trial to compare 2D conventional full field digital mammography (FFDM) with 3D digital tomosynthesis (DT) for breast cancer screening, is now open for enrollment in the United States. The study was developed by the ECOG-ACRIN Cancer Research Group and the National Cancer Institute. ECOG-ACRIN is leading the phase three clinical trial.
Alberta researchers receive multi-million dollar grant to study MRgFUS
A team of scientists at the Hotchkiss Brain Institute (HBI) of the University of Calgarys Cum-ming School of Medicine have been awarded a $3.2 million Canadian research grant from the Ca-nadian Foundation for Innovation (CFI) in Ottawa, Ontario. The grant is to research the use of magnetic resonance-guided focused ultrasound (MRgFUS).
