- Cognitive Impairment in Mild Traumatic Brain Injury: A Longitudinal Diffusional Kurtosis and Perfusion Imaging Study
DTI, diffusional kurtosis, and arterial spin-labeling were used in an attempt to detect abnormalities in 20 patients shortly after mild traumatic brain injury. These patients were also evaluated for attention, concentration, executive functioning, memory, learning, and information processing. At 1 and 9 months after injury, all patients showed significant abnormalities in gray and white matter by using all techniques and thus these methods may be useful in investigating cognitive impairment after brain injury.
- Yield of CT Angiography and Contrast-Enhanced MR Imaging in Patients with Dizziness
Which is the preferred imaging modality in patients presenting with isolated dizziness? These authors retrospectively evaluated CTA, contrast-enhanced MRI of the brain, and contrast-enhanced MRI of the internal auditory canals and temporal bones in a large group of patients and showed that all 3 are unlikely to identify significant findings that will lead to a change in clinical management in this situation.
- Diagnostic Evaluation in Patients with Intractable Epilepsy and Normal Findings on MRI: A Decision Analysis and Cost-Effectiveness Study
Here is an investigation designed to determine cost-effectiveness of diagnostic tests on patients with focal epilepsy and normal MRI. Studies compared were PET, ictal SPECT, and MEG, individually and in various combinations. PET + MEG and SPECT were the preferred imaging modalities and PET + MEG was favored when the willingness to pay was less than US $10,000, while SPECT was favored when the willingness to pay was above $10,000.
