A team of researchers at King’s College of the University of London (KCL) has developed a brain scan which can purportedly detect autism in adults. The scan, which uses MRI to obtain images of the brain, can identify autism based on the physical makeup of grey matter in the brain. Results of an initial study involving the scan were published in the Journal of Neuroscience today.
From the article:
The team used an MRI scanner to take pictures of the brain’s grey matter. A separate imaging technique was then used to reconstruct these scans into 3D images that could be assessed for structure, shape and thickness — all intricate measurements that reveal Autism Spectrum Disorder (ASD) at its root.
The research studied 20 healthy adults, 20 adults with ASD, and 19 adults with ADHD. All participants were males aged between 20 and 68 years. After first being diagnosed by traditional methods (an IQ test, psychiatric interview, physical examination and blood test), scientists used the newly-developed brain scanning technique as a comparison. The brain scan was highly effective in identifying individuals with autism and may therefore provide a rapid diagnostic instrument, using biological signposts, to detect autism in the future.
The Speech Production and Articulation Knowledge Group at the University of Southern California (USC) works on very interesting projects. If you’ve ever wondered what an MRI of vocal performance might look like, this is it. From USC:
This video illustrates real-time MRI of vocal performance. It includes examples from a soprano and an emcee/beatboxer. This video was featured at the Sounds and Visions Session of the International Society for Magnetic Resonance in Medicine (ISMRM) Scientific Sessions, May 2006, Seattle.
Boston Celtics basketball player Kendrick Perkins injured his knee during the NBA Finals against the Lakers when he landed awkwardly. Unable to weightbear, he left Game 6 not to return for the following pivotal Game 7.
How do doctors know what’s wrong without X-ray vision or an imaging test? (Note that Perkins did get a X-ray, but X-rays generally don’t show ligament injuries.) Is it guessing? Read more »
Thanks to the wonders of magnetic resonance imaging (MRI), amazing images of “heart strings” — the muscle fiber orientation of the left ventricle of the heart — have been obtained. According to the University of Oxford:
The image was produced using a branch of magnetic resonance imaging (MRI) called diffusion tensor imaging (DTI). The technique tracks the diffusion of water throughout the myocardium (the heart’s muscular wall comprising interconnected sheets of muscle cells called myocytes). Due to the way the myocytes are organized, the movement of water is restricted, so tracking the location of water molecules can reveal valuable information about the structure of the heart in a non-invasive way.
Nice.

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery.

I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
