- Assessing the Diagnostic Value of Brain White Matter Hyperintensities and Clinical Symptoms in Predicting the Detection of CSF-Venous Fistula in Patients with Suspected Spontaneous Intracranial Hypotension
The purpose of this retrospective cohort study was to assess the quantity and distribution pattern of WMH in patients with suspected SIH who underwent subsequent dynamic CTM. Patients with CVF had significantly higher Bern scores and significantly fewer WMH than those without CVF. Also, the migraine-type pattern of WMH was present at a nearly 4-fold greater frequency in the CVF- group versus the CVF+ group. Additionally, the symptom data demonstrated distinct clinical phenotypes between patients with CVF (eg, higher occurrence of a pressure-type or throbbing headache, symptoms worsening with the Valsalva maneuver) and those without CVF (eg, neck pain, fatigue, photophobia, and phonophobia).
- Change in Emergency Department Length of Stay following Routine Adoption of Dual-Energy CT to Differentiate Intracranial Hemorrhage from Calcification
This retrospective study compared ED LOS over a 1-year period before and after implementing automated DECT processing in the evaluation of indeterminate intracranial hyperdensities. The authors showed that with intracranial indeterminate hyperdensities, there was a larger statistically significant difference in pre-DECT versus post-DECT ED LOS. The pre-DECT ED LOS correlated with increased frequency of neurosurgical consultation and repeat head CT.
