Fig. 3C —40-year-old woman with hemangioma. Superparamagnetic iron
oxide (SPIO)-enhanced gradient-recalled echo images obtained with TEs of 9
(A), 13.5 (B), 18 (C), and 22.5 (D) milliseconds.
Signal intensity (SI) of both hemangioma (arrow) and liver decreased
as TE was lengthened, but loss of SI of lesion is more prominent because
contrast agent is pooling in lesion; hence, lesion conspicuity is decreased on
images obtained with longer TEs.
