      The Use of Noncontrast Quantitative MRI to Detect Gadolinium-Enhancing Multiple Sclerosis Brain Lesions: A Systematic Review and Meta-Analysis
      A. Gupta, K. Al-Dasuqi, F. Xia, G. Askin, Y. Zhao, D. Delgado and Y. Wang
      American Journal of Neuroradiology July 2017, 38 (7) 1317-1322; DOI: https://doi.org/10.3174/ajnr.A5209

      The authors evaluated 37 journal articles that included 985 patients with MS who had MR imaging in which T1-weighted postcontrast sequences were compared with noncontrast sequences obtained during the same MR imaging examination by using ROI analysis of individual MS lesions. DTI-based fractional anisotropy values were significantly different between enhancing and nonenhancing lesions, with enhancing lesions showing decreased FA. None of the other most frequently studied MR imaging biomarkers (mean diffusivity, magnetization transfer ratio, or ADC) were significantly different between enhancing and nonenhancing lesions. They conclude that noncontrast MR imaging techniques, such as DTI-based FA, can assess MS lesion acuity without gadolinium.

      This study included 47 patients from 10 centers presenting between January 2009 through April 2016with acute neck pain or tenderness and at least 1 cervical image showing unclassified carotid abnormalities. The authors conducted a systematic, retrospective study of their medical charts and diagnostic and follow-up imaging. All patients presented with acute neck pain, and 8 presented with transient neurologic symptoms. Imaging showed an eccentric pericarotidian infiltration in all patients. An intimal soft plaque was noted in 16 patients, and a mild luminal narrowing was noted in 16 patients. The authors conclude that this study improves the description of an unclassified, clinico-radiologic entity, which could be described by the proposed acronym: Transient Perivascular Inflammation of the Carotid artery (TIPIC) syndrome.

      Prevalence of Traumatic Findings on Routine MRI in a Large Cohort of Professional Fighters

      American Journal of Neuroradiology July 2017, 38 (7) 1303-1310; DOI: https://doi.org/10.3174/ajnr.A5175

      Conventional 3T MR imaging was used to assess 499 fighters (boxers, mixed martial artists, and martial artists) and 62 controls for nonspecific WM changes, cerebral microhemorrhage, cavum septum pellucidum, and cavum vergae. Fighters had an increased prevalence of cerebral microhemorrhage (4.2% versus 0% for controls), cavum septum pellucidum (53.1% versus 17.7% for controls), and cavum vergae (14.4% versus 0% for controls). This study assessed MR imaging findings in a large cohort demonstrating a significantly increased prevalence of cavum septum pellucidum among fighters. Although cerebral microhemorrhages were higher in fighters than in controls, this finding was not statistically significant.
