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).

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.

This retrospective single-center cohort study investigated the discrepancy of 2 widely used postprocessing tools (Syngo.via and RapidAI) for CTP in patients with medium/distal vessel occlusion (MDVO) stroke. The 2 postprocessing tools were discordant on the volume and the location of perfusion deficit in isolated MDVO as well as the volume of potentially salvageable penumbra. As such, this questions whether infarct core size or penumbra volume should routinely be used to identify candidates for MDVO thrombectomy.

Compared to traditional energy-integrating CT detectors, photon-counting CT allows greater spatial and contrast resolution of small channels containing nerves, arteries, and normal anatomy such as the cochlear cleft and cochlear and vestibular aqueducts. This review article updates the existing literature by redefining these structures in greater resolution.
