To investigate the integrity of the default-mode network (DMN) by using independent component analysis (ICA) methods in patients shortly after mild traumatic brain injury (MTBI) and healthy control subjects, and to correlate DMN connectivity changes with neurocognitive tests and clinical symptoms. ⋯ These results showed abnormal DMN connectivity patterns in patients with MTBI, which may provide insight into how neuronal communication and information integration are disrupted among DMN key structures after mild head injury.

To retrospectively determine the incremental diagnostic value of adding single photon emission computed tomography/computed tomography (SPECT/CT) to whole-body scintigraphy with iodine 131 ((131)I) compared with scintigraphy alone after radioiodine therapy in patients with well-differentiated thyroid carcinoma. ⋯ SPECT/CT improved detection and localization of (131)I accumulation in lymph node metastases and distant metastases, compared with whole-body scintigraphy.
