RSS Info – In this edition of HealthBeat, we discuss Neck Ultrasound and Prediction of Stroke, MRI techniques may detect early osteoarthritis, And Finally, a story about the Updated Medicare ABN Form.
Neck Ultrasound and Prediction of Stroke
A recent study in the journal Neurology, looked at the relationship of Cervical Ultrasound and predicting stroke.
Two noninvasive imaging tests may help determine which people with a narrowing of arteries in the neck will need surgery to reduce their future risk of stroke, a study suggests.
A narrowing of the carotid arteries in the neck is known as asymptomatic carotid stenosis (ACS). “Asymptomatic” means the patient does not experience any symptoms.
Carotid arteries in the neck deliver blood to the brain. They typically become narrowed when plaques build up in the inner lining of the arteries.
There is some uncertainty within the medical community on how to best identify people with ACS who are at high risk for stroke and need surgery or stenting to open their carotid arteries as opposed to treatment with medication.
In a two-year study of 435 people with severe ACS, researchers used ultrasound to assess the quality and composition of the plaque in the carotid arteries and a Doppler ultrasound test to look for the presence of tiny blood clots or particles called microemboli that may break off from the arteries and travel to the brain, causing stroke.

MRI techniques may detect early osteoarthritis
Researchers from the New York University Langone Medical Center have found that advanced MRI techniques could be used to detect subtle changes in joint cartilage microstructure and provide physicians with a diagnostic tool for locating key markers of early osteoarthritis.
Using these techniques during patient exams to facilitate earlier identification of osteoarthritis (OA) can shift the focus of management from eventual joint reconstruction to long-term preservation, according to the review article — published in the Journal of the American Academy of Orthopaedic Surgeons.
“Imaging technology is now sensitive and powerful enough to enable detection of subtle changes in the intricate balance of water, chondrocytes and the collagen fibers and protein molecules that make up our joint cartilage — which we know can point to future [OA],” lead author Laith Jazrawi, MD, stated in a press release from the NYU Langone Medical Center.
Damaged cartilage shows distinct changes in the concentration of water and collagen molecules, the micro- and macrostructure of collagen and glycosoaminoglycan concentrations.
The authors noted that these techniques have yet to be used to any significant extent in the clinical field, but added that the potential for their clinical use is evident.

Updated Medicare ABN Form
The Centers for Medicare & Medicaid Services (CMS) has released a revised Advanced Beneficiary Notice of Non-Coverage (ABN) CMS-R-131 form. The ABN is issued by providers in situations where Medicare payment is expected to be denied.
The revised ABN replaces the ABN-G (Form CMS-R-131G), ABN-L (Form CMS-R-131L), and NEMB (Form CMS-20007).The mandatory use date is November 1, 2011.
The changes to the revised ABN form and instructions are very minor:
The new form can be distinguished from the current form by reviewing the release date located in the lower left corner of the form. Revised forms list a date of 03/11. ABN forms issued on or after November 1, 2011 with a release date of 03/08 or prior will be considered invalid.
CMS also recently released a new ABN booklet containing instructions for issuing these forms for both Medicare Part A and Part B.
Read more about the ABN and download the new version from the CMS website.
