To analyze brain activation patterns in response to tests of working memory after a mild traumatic brain injury (MTBI). ⋯ MTBI-induced differences in working memory functional activity were observed even though differences in behavioral performance between MTBI patients and controls were absent, which suggests that this approach may increase sensitivity to MTBI compared with neuropsychological evaluation alone.

To determine whether the difference of resistive indexes (RIs) in spleen and kidney (DI-RISK) is a more specific ultrasonographic (US) marker of intrarenal parenchymal damage than intrarenal RI alone. ⋯ In patients with chronic kidney disease, renal RIs do not selectively indicate organ damage, but also mirror systemic vascular disease. The authors introduced DI-RISK as a potential US marker that may more specifically reflect kidney damage.

To evaluate the safety and efficacy of pelvic arterial embolization (PAE) for the treatment of primary postpartum hemorrhage (PPH) and to determine the factors associated with clinical outcomes. ⋯ PAE is safe and effective for managing primary PPH. Patients with DIC and massive transfusion were likely to have poor results after PAE.
-
To determine if the combination of gadoxetic acid-enhanced magnetic resonance (MR) imaging and diffusion-weighted (DW) imaging helps to increase accuracy and sensitivity in the diagnosis of small hepatocellular carcinomas (HCCs) compared with those achieved by using each MR imaging technique alone. ⋯ The combination of gadoxetic acid-enhanced MR imaging and DW imaging yielded better diagnostic accuracy and sensitivity in the detection of small HCCs than each MR imaging technique alone.
-
To evaluate whether contrast material-enhanced (CE) fast imaging employing steady-state acquisition (FIESTA) can depict the anterior optic pathways in patients with large suprasellar tumors. ⋯ CE FIESTA is useful for the preoperative localization of the anterior optic pathways in patients with large suprasellar tumors and offers the potential to predict persistent visual impairment after decompression.
