In the article by Staals et al, “Brain Microbleeds Relate to Higher Ambulatory Blood Pressure Levels in First-Ever Lacunar Stroke Patients,” which was published ahead-of-print on August 6, 2009, and appeared in the October issue of the journal (Stroke. 2009;40:3264–3268) a correction was needed.
Methods: MR images were obtained at an 1,5T MRI scanner (n=94, 76%) or 3T MRI scanner (n=29, 24%).
The authors became aware of the use of different MRI field strengths in their patient population after publication of the results. Several exploring reanalyses (to eliminate possible overrating of microbleeds in patients scanned at 3T compared to 1,5T) on the data showed similar results. The authors conclude that the results and conclusions as published remain valid.
