Benign notochordal cell tumor is a benign intraosseous lesion, demonstrates characteristic imaging features. The lesion demonstrates low-signal intensity in T1-weighted images, high-signal intensity in T2-weighted images, and no enhancement with contrast medium in MRI and slight osteosclerosis in CT. If typical imaging findings are identified, biopsy is not necessary.
良性脊索细胞瘤是一种良性骨内病变，具有特征性影像学表现。该病变在T1加权图像上呈低信号强度，在T2加权图像上呈高信号强度，在MRI上无造影剂强化，在CT上有轻微骨质硬化。如果发现典型的影像学表现，则无需进行活检。
