We first measured the contrast-to-noise ratio (CNR) using an agar phantom that contained different concentrations of superparamagnetic iron oxide (SPIO). The acquisition time for SWAN and T2*-WI was similar (182 vs. 196\u2009s). Neuroradiologists compared the two imaging methods for lesion detectability and conspicuity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The CNR of the phantom was higher on SWAN images. Of the 75 patients, 50 were found to have a total of 278 cerebral hemorrhagic lesions (microbleeds, n\u2009=\u2009229 [82.4%]; intracerebral hemorrhage, n\u2009=\u200918 [6.5%]; superficial siderosis, n\u2009=\u200913 [4.7%]; axonal injuries, n\u2009=\u20098 [2.9%]; subarachnoid hemorrhage [SAH] or brain contusion, n\u2009=\u20093 each [1.0%]; subdural hematoma, n\u2009=\u20092 [0.7%]; cavernous hemangioma or dural arterteriovenous fistula, n\u2009=\u20091 each [0.4%]). In none of the lesions was the SWAN sequence inferior to T2*-WI with respect to lesion detectability and conspicuity. In fact, SWAN yielded better lesion conspicuity in patients with superficial siderosis and SAH: it detected significantly more lesions than T2*-WI ( P\u2009&lt;\u20090.01) and it was particularly useful for the detection of microbleeds and lesions near the skull base.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SWAN is equal or superior to standard T2*-WI for the diagnosis of various cerebral hemorrhagic lesions.
