Federal law generally prohibits physicians from referring their own patients to a diagnostic facility in which they have an ownership issue — a practice called “self-referral” — unless the facility is located in their own practice. This exemption exists to allow patients with access to a laboratory test, X-ray, or other imaging test at the same time and place as when patients are seeing their physician for an office visit. Less inconvenience and speeder diagnosis and treatment — what could be wrong with that?
Much, say the critics, if it leads to overutilization and higher costs and doesn’t really represent a convenience to patients. This is the gist of two studies by staff employed by the American College of Radiology, published in the December issue of Health Affairs.
One study analyzes Medicare claims data and concludes that patients aren’t really getting “one-stop-shopping” convenience when their physician refers them to an imaging facility that qualifies for the “in-office” exemption.
“Specifically, same-day imaging was the exception, other than for the most straightforward types of X-rays. Overall, less than one-fourth of imaging other than these types of X-rays was accompanied by a same-day office visit. The fraction for high-tech imaging was even lower — approximately 15 percent.” Read more »

An international team of researchers has developed a rather reliable test that predicts the future improvement of reading abilities in kids with dyslexia. The method uses functional MRI (fMRI) and diffusion tensor magnetic resonance imaging (DTI) to scan the brain, and data crunching software to interpret the data. The researchers hope that the finding will help parents and therapists uniquely identify which learning tools are best for each child.
From the announcement by Vanderbilt University :
The 45 children who took part in the study ranged in age from 11 to 14 years old. Each child first took a battery of tests to determine their reading abilities. Based on these tests, the researchers classified 25 children as having dyslexia, which means that they exhibited significant difficulty learning to read despite having typical intelligence, vision and hearing and access to typical reading instruction.
During the fMRI scan, the youths were shown pairs of printed words and asked to identify pairs that rhymed, even though they might be spelled differently. The researchers investigated activity patterns in a brain area on the right side of the head, near the temple, known as the right inferior frontal gyrus, noting that some of the children with dyslexia activated this area much more than others. DTI scans of these same children revealed stronger connections in the right superior longitudinal fasciculus, a network of brain fibers linking the front and rear of brain. Read more »

The Associated Press ran a provocatively-titled piece recently, “Family health history: ‘best kept secret’ in care”, which noted how a geneticist at the Cleveland Clinic discovered that asking about family members and their history of breast, colon, or prostate cancer was better than simply doing genetic blood testing.
Surprising? Hardly. This is what all medical students are taught. Talk to the patient. Get a detailed history and physical. Lab work and imaging studies are merely tools that can help support or refute a diagnosis. They provide a piece of the puzzle, but always must be considered in the full context of a patient. They alone do not provide the truth. Read more »

I present interesting cases to colleagues often because it’s educational and good for patient care and because I like to. But it has been many years since I was mandated to present a case.
It seems that I’m not the only doctor exasperated by a pesky new barrier to patient care: Doctors in cubicles.
An old friend and mentor, Dr. Richard Kovacs, now chair of the American College of Cardiology’s Board of Governors (and IU guy), has written about these same pre-certification barriers. Dr. Kovacs, being a professor and distinguished ACC official, kindly terms these obstructionists “radiology benefit managers” (RBMs). 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.
