MRI makes the timing of strokes determinable

Honored for the development of a method that makes it possible to determine the time of past strokes using magnetic resonance imaging (MRI). The Board of Trustees of Dr. Martini Foundation awarded the DR. MARTINI PRIZE 2012 to the neurologist Dr. Götz Thomalla from the University Medical Center Hamburg-Eppendorf.

The neurologist had developed an MRI procedure with which the timing of a previous stroke can be determined relatively precisely. For this, Dr. Götz Thomalla with the prestigious Dr. Martini Foundation, which has been awarded annually since 1883 on February 12, the anniversary of Dr. Erich Martinis. The DR. MARTINI-PRICE, endowed with 3,000 euros, is the oldest medical award in Germany and annually awards the best work done in Hamburg.

Timing of strokes enables thrombolysis Dr. Götz Thomalla was honored for demonstrating that it is possible to use MRI to narrow down the timing of a stroke, according to the Hamburg-Eppendorf University Hospital (UKE). Based on this time limitation, patients who suffered a stroke while sleeping could also receive thrombolysis (dissolution of blood clots), reports the UKE. To date, they have been excluded from this treatment. In most cases, blood clots trigger the stroke, closing an artery in the brain, causing circulatory disorders and damage to the affected brain regions. During thrombolysis, these blood clots are dissolved with the help of medication to avoid further health consequences. However, thrombolysis is only promising in the first four and a half hours after the first symptoms appear. Since "but 20 percent of strokes take place at night during sleep" and it remains completely unclear "when the stroke occurred", numerous stroke patients have so far been excluded from thrombolysis, explained Dr. Thomalla at the award ceremony.

Significant progress in stroke therapy The Hamburg neurologist's MRI procedure helps here by allowing a relatively precise chronological classification of past strokes. "Dr. Thomalla's study results represent significant advances in stroke therapy and open up new treatment prospects for patients, ”said the chairman of the board of trustees of the Dr. Martini Foundation and director of the 1st Medical Clinic at UKE, Professor Ansgar Lohse, justifying the award ceremony. The scientific focus of the award winner lies in the imaging of cerebrovascular diseases (circulatory diseases of the brain) and the neurophysiology of diseases of the motor system. Dr. has particularly excelled Thomalla with the project "Selection of patients for intravenous thrombolysis using multimodal stroke MRI imaging (perfusion and diffusion-weighted MRI)". (fp)
