Comparative Study
Symptomatic white matter changes in mild traumatic brain injury resemble pathologic features of early Alzheimer dementia.
To evaluate white matter integrity in patients with mild traumatic brain injury (TBI) who did not have morphologic abnormalities at conventional magnetic resonance (MR) imaging with diffusion-tensor imaging to determine any relationship between patterns of white matter injury and severity of postconcussion symptoms. ⋯ The distribution of white matter abnormalities in patients with symptomatic mild TBI is strikingly similar to the distribution of pathologic abnormalities in patients with early Alzheimer dementia, a finding that may help direct research strategies.

To develop and validate a mathematical radiation dose optimization model for computed tomography (CT) of the chest, abdomen, and pelvis. ⋯ CT image quality and radiation dose can be mathematically predicted and optimized on the basis of patient size and radiologist-specific image noise target curves.

To assess clinical and ultrasonographic (US) criteria that can be used to confidently differentiate ileocolic from small-bowel intussusception. ⋯ The presence of an inner fatty core in the intussusception, lesion diameter, wall thickness, the ratio of fatty core thickness to outer wall thickness, and the presence of lymph nodes in the lesion may enable reliable differentiation between ileocolic and small-bowel intussusceptions.

To characterize the 100 most-cited articles in medical imaging. ⋯ Preclinical articles, primarily in the field of neurologic MR imaging, were highly represented in the top 100 cited articles in the medical imaging literature.
