Abstract:
Objective To evaluate the value of MRI in diagnosing the premature closure and other deformities of the growth plate followed physeal injury. Methods Twenty-one children with suspected or known premature closure of the growth plate followed injury were examined with X-ray and MRI. In addition to conventional T 1WI and T 2WI for all cases, 8 were also examined with spectral pre-saturation inversion recovery sequence. The value of MRI in diagnosing and imaging the premature closure of the growth plate (PCGP) was analyzed. Results PCGP was seen in all 21 cases, 6 in the distal femur, 6 in the proximal tibia, and 9 in the distal tibia. 19 patients with angular deformities and 2 cases with both angular and shorten deformities. MRI can much more clearly visualize the cartilage of the growth plate than conventional X-ray. A stripe of low signal intensity through the cartilage of the growth plate indicated premature closure of the growth plate. 8 cases with spectral pre-saturation inversion recovery sequence can visualize the PCGP more clearly than with Spin Echo and Fast Field Echo. Conclusion MRI has an important role in diagnosing and visualizing the PCGP. The configuraton of the PCGP can be accurately mapped with MR imaging and treatment planning is facilitated.
