腰椎Modic 改变 （II型）

Four hundred eighty-seven patients (263 women and 224 men) undergoing lumbar spine MRI examination for chronic ow back pain(LBP).‘‘Chronic’’ was defined as LBP lasting for 3 months or more.
RESULTS:Modic changes were found in 81% of the patients. The most common was Type II(51.3%), affecting only the end plate.[1]

以下是临床上遇到的一名Modic 2型患者的影像资料。
A 44 year old male worker sustained chronic low back pain(LBP) for more than 5 years.
Imaging examination is shown below.

Fig A. Sagittal T2-weighted MRI showing hyperintensity at L5–S1 bone marrow and intervertebral level.
Fig B. Sagittal T1-weighted MRI showing hyperintensity at L5–S1 bone marrow and intervertebral level.
Fig C. Sagittal the fat-suppression sequence image showing hyperintensity was turned into hypointensity.



Modic type 2 changes:
high signal in T1-weighted sequences,
high or intermediate signal in T2-weighted sequences.
Corresponding histologic appearance:fatty replacement of the adjacent marrow.
