Determination of patellar ligament and anterior cruciate ligament geometry using MRI

H. P. Wang, Cui, H. K., Yue, W., Yan, R. F., Ren, J. P., Zhai, Z. S., Liang, C. H., Yang, R. M., and Han, D. M., Determination of patellar ligament and anterior cruciate ligament geometry using MRI, vol. 14, pp. 12352-12361, 2015.

Ligament geometry is crucial to surgical treatment success in anterior cruciate ligament (ACL) injury. This study aimed to optimize the MRI technique to elucidate the geometry of the patellar ligament (PL) and ACL in vivo. A 1.5-T superconducting MRI system with a special surface coil and fast spin echo was used to acquire high-resolution T1-weighted images (H-T1WI) of the ACL. The sagittal plane angle was 10° to 15° towards the inner side of the vertical line of the tangent line axis of the femoral intercondylar fossa.

Study of white matter at the centrum semiovale level with magnetic resonance spectroscopy and diffusion tensor imaging in cerebral small vessel disease

L. A. Huang, Ling, X. Y., Li, C., Zhang, S. J., Chi, G. B., and Xu, A. D., Study of white matter at the centrum semiovale level with magnetic resonance spectroscopy and diffusion tensor imaging in cerebral small vessel disease, vol. 13, pp. 2683-2690, 2014.

White matter lesion (WML) in magnetic resonance imaging is commonly observed in patients with cerebral small vessel disease (SVD), but the pathological mechanism of WML in SVD is still unclear. We observed the metabolism and microscopic anatomy of white matter in SVD patients. Twelve subjects clinically diagnosed with SVD and 6 normal control subjects were examined with magnetic resonance spectroscopy (MRS) and diffusion tensor imaging (DTI). The white matter at the centrum semiovale level was selected as the region of interest (ROI).

Comparison of computed tomography and magnetic resonance imaging in the evaluation of facet tropism and facet arthrosis in degenerative cervical spondylolisthesis

C. Xu, Ding, Z. H., and Xu, Y. K., Comparison of computed tomography and magnetic resonance imaging in the evaluation of facet tropism and facet arthrosis in degenerative cervical spondylolisthesis, vol. 13, pp. 4102-4109, 2014.

The aim of this study was to determine the reliability of magnetic resonance imaging (MRI) in the assessment of facet tropism and facet arthrosis of spondylolisthesis levels in degenerative cervical spondylolisthesis as compared to computed tomography (CT). The discrepancies in the interpretation of CT and MRI data in the evaluation of facet tropism and arthrosis have given rise to questions regarding the reliability of comparisons of the two techniques.

Value of diffusion weighted imaging in the differential diagnosis of benign and malignant breast lesions at 3.0T MRI

X. Y. Jiang, Xie, Q. Z., Cao, X. S., Gao, T., Xing, C. Y., and Li, X. L., Value of diffusion weighted imaging in the differential diagnosis of benign and malignant breast lesions at 3.0T MRI, vol. 13, pp. 7773-7779, 2014.

The aim of this study was to investigate the correlation between apparent diffusion coefficients (ADCs), the relative apparent diffusion coefficient (rADC), and the pathological prognostic factor human epidermal growth factor receptor 2 (HER-2) in patients with breast cancer. A total of 64 women with breast cancer underwent breast diffusion-weighted imaging. HER-2 expression was detected in histological specimens. The ADC value, rADC value, and HER-2 level were determined.

Clinical image and pathology of hypertrophic cranial pachymeningitis

C. H. Shi, Niu, S. T., and Zhang, Z. Q., Clinical image and pathology of hypertrophic cranial pachymeningitis, vol. 13, pp. 10501-10509, 2014.

The objective of this study was to examine the clinical findings, magnetic resonance imaging (MRI), pathological features, and treatment experiments of patients with hypertrophic cranial pachymeningitis (HCP). The clinical findings, MRI, and pathological appearances of 9 patients with HCP were analyzed retrospectively. The thickened dura mater was markedly enhanced after contrast media injection. The lesion near the brain hemisphere presented long regions of T1- and T2-weighted abnormal signal intensities.

Combined genetic and imaging diagnosis for two large Chinese families affected with Pelizaeus-Merzbacher disease

Y. Lv, Cao, L. H., Pang, H., Lu, L. N., Li, J. L., Fu, Y., Qi, S. L., Luo, Y., and Li-Ling, J., Combined genetic and imaging diagnosis for two large Chinese families affected with Pelizaeus-Merzbacher disease, vol. 11, pp. 2035-2044, 2012.

Pelizaeus-Merzbacher disease (PMD) is a rare X-linked recessive disorder characterized by nystagmus, impaired motor development, ataxia, and progressive spasticity. Genetically defective or altered levels of proteolipid protein (PLP1) or gap-junction alpha protein 12 gene have been found to be a common cause. Here we report on two large Han Chinese families affected with this disease. The probands of both families had produced sons featuring cerebral palsy that had never been correctly diagnosed. PMD was suspected after careful analysis of family history and clinical features.
