    MRI was performed as an additional study to evaluate the extent of the Fibrous Dysplasia lesions and to demonstrate their internal structure. T1-weighted MR images showed low-intensity lesions corresponding to the lesions identified on CT. (A)The skull base lesions were remarkably enhanced on T1-weighted MR images after intravenous injection of gadolinium–diethylenetriaminepentaacetic acid (Gd-DTPA). MRI (Magnetic resonance imaging)核磁共振攝影是一項用來評估纖維性發育不良病變程度和證明內部結構的額外的研究。T1加權核磁共振影像顯示出與電腦斷層掃描(Computerized Tomography, CT)所發現病變一致的低強度病變。(A)在靜脈注射釓-二乙三胺五乙酸(diethylenetriaminepentaacetic acid , Gd-DTPA)之後,T1加權核磁影像上的顱底病變被明顯的強化。 T2-weighted MR images showed low-intensity lesions with a high signal component. (B)Heterogeneous intensity in the right frontal bone marrow with slight deformity of the outer table of the skull was noted on coronal contrast-enhanced T1-weighted MR images. This finding was not pointed out on the first interpretation without knowing the results of bone scintigraphy. T2加權核磁影像以一個高信號份量顯示低強度病變。(B)顱骨外板些微變形的右前額骨髓內非均質訊號表現在切冠面對比增強T1加權核磁影像中被發現。這個發現在未知骨骼造影結果下的第一次說明中未被指出。 MRI may be used to evaluate the extent of a lesion or its internal structure in FD, rather than for diagnosis.6 MRI is useful for surgical planning.7 However, slight changes at unexpected sites, as seen in our patient, may be difficult to interpret, even on MRI. MRI of FD may mimic that of tumors, especially when T2-weighted images show high signal intensities, and postcontrast T1-weighted images show enhancement of lesions,8 as seen in our patient. MRI核磁共振攝影可以用來評估病變的範圍和它的碎形分析(fractal dimension, FD)內部結構而非診斷。6. 核磁共振攝影對於手術計畫有幫助。7. 然而,就像在我們的病人身上所看到的,即使是核磁共振攝影,些微不預期的位置改變可能都很難解釋。碎形分析(fractal dimension, FD)的核磁共振攝影可能模仿腫瘤,特別是當T2加權影像顯示高訊號強度時,而對比後的T1加權影像顯示病變的強化。8. 就像在我們的病人身上所看到的,
