Male sex and uncinated fasciculus (UF) values are independent risk factors for persistent postconcussion symptoms after three months and are stronger predictors of time to symptom resolution (TSR) than initial symptom severity, new research shows.
Saeed Fakhran, M.D., of the University of Pittsburgh School of Medicine, and colleagues retrospectively reviewed diffusion tensor imaging (DTI) in 69 patients with mild traumatic brain injury (mTBI)—47 male and 22 female patients—and 21 control subjects—10 male and 11 female subjects—with normal conventional MR images.
Patients with mTBI underwent serial neurocognitive testing with Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Correlation between sex, white matter FA values, ImPACT scores and time to symptom resolution (TSR) were analyzed with multivariate analysis and tract-based spatial statistics (TBSS).
Male patients with mTBI have significantly decreased fractional anisotropy (FA) values in the UF bilaterally (P < .05) compared with female patients with mTBI and control subjects, results showed.
“This finding may indicate a role for UF FA values as a sex-neutral metric for evaluating the severity of mTBI injuries and predicting subsequent clinical outcome,” the authors write.
Structured reporting of incidental CT findings can mediate accurate stratification of individuals into clinically relevant risk categories and subsequently allow those at higher risk of future cardiovascular (CVD) events to be distinguished, new research shows.
In a retrospective study by Pushpa M. Jairam, M.D., Ph.D., of the University Medical Center Utrecht, the Netherlands, the derivation cohort comprised 10,410 patients who underwent diagnostic chest CT for noncardiovascular indications. During a mean follow-up of 3.7 years (maximum, 7.0 years), 1,148 CVD events were identified. By using a case-cohort approach, CT scans from the cases and from an approximately 10 percent random sample of the baseline cohort (n = 1,366) were graded visually for several cardiovascular findings.
The final model demonstrated good discriminative value, with a C statistic of 0.71 (95 percent confidence interval: 0.68, 0.74) and a good overall calibration, as assessed in the validation cohort.
“The use of the score derived in this study is simple and quick and allows accurate stratification of individuals into clinically relevant risk categories and permits those at risk for CVD events in the near future to be distinguished,” the authors write.
In May, 1,224 RSNA-related news stories were tracked in the media. These stories reached an estimated 257 million people.
A study published online in Radiology received widespread attention in the press during April and May. “Effect of Diabetes on Brain Structure: The Action to Control Cardiovascular Risk in Diabetes MR Imaging Baseline Data,” was covered by more than 875 print, broadcast and online outlets, including Time, Newsday, U.S. News & World Report, Doctor Radio, KCAL-TV (Los Angeles), MSN.com, Yahoo! Health, CNN.com, FoxNews.com and WebMD.
Outlets covering other studies included WGN America, WABC-TV (New York), KABC-TV (Los Angeles), WBBM-TV (Chicago), Los Angeles Times, Chicago Tribune, The Huffington Post, Toronto Sun and Philly.com.
