, after injection of a double dose (0.2 mmol/kg body weight) of contrast agent. A) presents the results for the medial meniscus, showing that the mean values over time were significantly lower in the posterior (ο) than in the anterior (•) horn of the meniscus (ANOVA, p = 0.015). B) presents the results for the medial and lateral posterior meniscus, showing that ΔR1 was lower in the medial (ο) than in the lateral (•) horn (ANOVA, p = 0.049).
