Multifunctional microbubble agents that integrate several diagnostic and therapeutic functions have great potential for future medical applications. For example, superparamagnetic iron oxide (SPIO) nanoparticles currently used as MRI contrast agents could be combined with encapsulated microbubbles,

"Dot-in-circle" sign described as diagnostic for musculoskeletal mycetoma on MRI and Ultrasound
This open source paper (link downloads the paper as a .pdf file) presents the ‘dot-in-circle’ sign, which indicates the typical magnetic resonance imaging (MRI) and ultrasonographic (USG) findings for mycetoma involving soft tissue and bone. (Illustrations are at the end of the paper)

Health care reform will slow down the USA diagnostic imaging market
Health care reform and the shift from the fee-for-service to a value-based payment model will have a negative impact on the diagnostic imaging market in the U.S., according to a new report

How an old technology (Ultrasound) has become a disruptive innovation in medicine
In this brief TEDMED talk, Resa Lewiss, Director of Point-of-Care Ultrasound at the University of Colorado School of Medicine talks about POC/POS ultrasound and what this has meant for doctors and patients and for treatment of a variety of diseases.

Handheld photoacoustic probe produces detailed images of blood vessels, other structures
The new device combines two imaging modalities: ultrasound and photoacoustics in which short pulses of light heat up internal tissue. The slight temperature change leads to a change in pressure, which in turn produces a wave of ultrasound that can be analyzed to reveal information about the body's i

South Korea's Thyroid Cancer Rise: A Cautionary Tale?
South Korea's fast-rising rate of thyroid cancer in the past two decades appears to be the result of commonplace screening and is a "cautionary tale for the rest of the world," say the authors of aPerspective published in the November 6 issue of the New England Journal of Medicine.

Imaging Cancer with Sound and Light
Photoacoustic Tomography (PAT) converts light into sound waves which are then used to form images. PAT can now achieves imaging depths of up to 7 cm, revealing details of hemoglobin concentration and oxygen saturation within tissue.

Contrast enhanced ultrasound expands at Point of Care
Once considered an add-on examination, contrast enhanced ultrasound (CEUS) at point of care by clinicians expands diagnostic capabilities and is leading to new insights.

New Breast Imaging Technique May Allow Doctors to Eliminate the Need for Breast Biopsies
Seno Medical's Imagio breast imaging system uses opto-acoustic technology to help distinguish between benign and malignant breast lesions.

High-speed Intravascular 'label-free' photoacoustic imaging could reveal dangerous plaques
Purdue University Researchers are close to commercializing a photoacoustic imaging technology that could diagnose cardiovascular disease by measuring ultrasound signals from molecules exposed to a fast-pulsing Raman laser.

Will ultrasound-on-a-chip make medical imaging so cheap that anyone can do it?
A scanner the size of an iPhone that you could hold up to a person’s chest and see a vivid, moving, 3-D image of what’s inside is being developed by entrepreneur Jonathan Rothberg.

Researchers develop new technique to create cellular scaffolding for tissue engineering
Researchers at the University of Washington have developed a way to use sound to remove cells from tissue, leaving behind a cellular scaffolding for tissue engineering, a unique approach that could help overcome one of regenerative medicine's significant obstacles.

Are my muscular dystrophy drugs working?
People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked ultrasound device.

Kidney Stone Imaging Guidelines Not Being Followed in Kids
The "go-to" imaging modality for suspected kidney stones in children is computed tomography (CT), despite national guidelines recommending ultrasound as the preferred initial imaging, according to results from a recent study.

Focused Ultrasound Symposium Showcases Latest in Clinical and Research Advances
The 4th International Symposium on Focused Ultrasound featured clinical and research advances on the use of this non-invasive therapeutic technology to treat conditions as diverse as Parkinson’s disease and essential tremor, obsessive compulsive disorder, cancers, hypertension and uterine fibroids.

Technological Advances Offer 'Unprecedented Opportunity"
Eric Topol's keynote speech during the opening session of the 2014 AAFP Assembly addressed advances in technology and the potential they hold to transform health care for physicians and patients. Topol demonstrated by attaching a device to his phone and performing an echocardiogram on himself.
