Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Small coils activate neurons to modulate brain-cell activity

Magnetic fields generated by microscopic devices implanted into the brain may be able to modulate brain-cell activity and reduce symptoms of several neurological disorders.

MRI scans determine whether chemotherapy is working long before tumors shrink

Studies on some 55 U.S. men and women with potentially deadly liver or pancreatic cancers show that specialized MRI scans can tell within a month whether highly toxic chemotherapy is working and killing tumor cells long before tumors actually shrink – or fail to shrink.

Computer tomography delivers dependable data to analyze the heart's global pump function

Computer tomographic images deliver dependable data to analyze the heart's global pump function. This was shown in a study conducted by radiologists and cardiologists at Charité - Universitätsmedizin in cooperation with the Jena University Hospital.

New methods to track stem cells

Researchers at the University of Liverpool have developed new methods to track stem cells and further understanding of what happens to them after they have been in the body for a significant period of time.

Significant increase in use of CT, MRI and PET imaging over the last two decades

Among six large integrated health care systems between 1996 and 2010 there was a substantial increase in the use of advanced diagnostic imaging, including approximately a tripling of the use of computed tomography and nearly a quadrupling of the use of magnetic resonance imaging, as well as a substantial increase in estimated radiation exposure, according to a study in the June 13 issue of JAMA.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Effective ways of detecting onset of kidney disease

Research led by an Arizona State University biomedical engineer and physicist to find more effective ways of detecting the onset of kidney disease is getting support from the National Institutes of Health.

Concussion victims have unique spatial patterns of brain abnormalities that change over time

Patients vary widely in their response to concussion, but scientists haven't understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time

Risk of leukaemia and brain cancer in children could be tripled by radiation exposure from CT scans

Radiation exposure received from 2 to 3 computed tomography (CT) scans of the head in childhood (aged under 15 years)—giving a cumulative dose of around 60 mGy— can triple the risk of later developing brain cancer, while around 5 to 10 such scans (cumulative dose around 50 mGy) could triple the risk of developing leukaemia (with the differing number of scans related to different absorption rates of the brain versus the bone marrow and age at time of scanning).

Safety of breast implants

Following the recent scandal, described in May 2012 by the BBC as the “PIP breast implant scandal”, (1) many women may have been put off having breast implants. But how safe exactly is breast enlargement? And how do the different methods compare?

MRI provides early indication of breast tumor's response to pre-surgical chemotherapy

Magnetic resonance imaging (MRI) provides an indication of a breast tumor's response to pre-surgical chemotherapy significantly earlier than possible through clinical examination, according to a new study published online in the journal Radiology.

New research reveals effective treatments for gastrointestinal conditions

New research being presented at Digestive Disease Week- (DDW) reveals effective treatments for a number of gastrointestinal conditions, which are often chronic and costly.

TJU researchers to investigate Cu-64 imaging agent for prostate cancer

Jefferson's Kimmel Cancer Center and the Department of Radiology at Thomas Jefferson University received a five-year, $2.6 million grant from the National Institutes of Health (NIH) to investigate a potentially revolutionary method that can stage prostate cancers and detect recurrent disease so accurately, it would significantly reduce the number of confirmation biopsies. Such biopsies can be invasive, costly, and often lead to false-positive readings.

IGABT effective at controlling return and spread of cervical cancer

Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies, according to research presented at the World Congress of Brachytherapy today.

Psychopaths’ brains differ from healthy non-offenders: Study confirms

Approximately half of male prisoners in England and Wales will meet diagnostic criteria for ASPD. The majority of such men are not true psychopaths (ASPD-P). They are characterized by emotional instability, impulsivity and high levels of mood and anxiety disorders. They typically use aggression in a reactive way in response to a perceived threat or sense of frustration.

Researchers find talking about ourselves triggers sensation of pleasure

According to researchers, talking about ourselves - whether in a personal conversation or through social media sites like Facebook and Twitter - can trigger the same sensation of pleasure in the brain as food, money or sex.

Researchers examines whether MRI can improve accuracy of Huntington’s diagnosis

Huntington disease (HD) is an inherited neurodegenerative disorder caused by a defect on chromosome four where, within the Huntingtin gene, a CAG repeat occurs too many times. Most individuals begin experiencing symptoms in their 40s or 50s, but studies have shown that significant brain atrophy occurs several years prior to an official HD diagnosis. As a result, the field has sought a preventive treatment that could be administered prior to the development of actual symptoms that might delay the onset of illness.
