Engineers have determined, for the first time, the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart, and have developed a novel ultrasound technology that makes screening cheaper and much easier, making it possible to reach a large number of people and even infants.

Researchers have created “a tool for blood-barrier-brain disruption that uses bursts of sub-microsecond bipolar pulses to enhance the transfer of large molecules to the brain.” According to the authors, the current medical use of chemotherapy to treat brain cancer can be inefficient because of the blood-brain-barrier that impedes the delivery of drugs out of blood vessels and into the tumor.

As of October 2014, 19 states have enacted laws requiring women to be directly informed if they have dense breasts and would benefit from supplemental screening. However, the recommended type of supplemental screening for women with dense breasts remains unclear. With 15 additional states considering similar laws and federal legislation introduced, physician scientists investigated the potential impact of supplemental screening for women with dense breast tissue.

It is now possible, for the first time, to demonstrate that the areas of the brain that are important for understanding language can be pinpointed much more accurately using ultra-high-field MRI (7 Tesla) than with conventional clinical MRI scanners. This research helps to protect these areas more effectively during brain surgery and avoid accidentally damaging it.

Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the "r" sound, rather than being instructed to make a specific shape.

New investigation methods using functional magnetic resonance tomography (fMRT) offer insights into fetal brain development. These "in vivo" observations will uncover different stages of the brain's development. A research group has observed that parts of the brain that are later responsible for sight are already active at this stage.

It has been more than 30 years since the last major advancement in prostate cancer screening technology, and the latest advancement is now available in the United States. It is estimated that 2014 will see more than 240,000 new cases of prostate cancer, and more than 29,000 deaths from the disease.

It may be possible to use Diffuse Optical Spectroscopic Tomographic imaging (DOST) to predict which patients will best respond to chemotherapy used to shrink breast cancer tumors before surgery, a study shows.

Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists.
