ConclusionsUsing 100 kVp and Iodixanol(270 mg I/ml) combined with iDose 4-4 iterative reconstruction technique for CT angiography of lower extremities, the image quality could meet the requirement for clinical diagnosis, the radiation dose and the volume of contrast medium could be lowered. KEYWO...

Thirty one consecutive patients strongly suspected of severe Middle Cerebral Artery AIS presenting less than 6 h after onset of symptoms or with unknown time of onset of symptoms underwent a standardized CT protocol in spectral mode including Non Contrast CT, mCTA, and Perfusion CT (CTP) on a ...
Furthermore, the same radiologists placed 3D boxes for collaterals along with their collateral scores (good or poor) onto two brain hemispheres, starting from the basal ganglia level and ending at the top of the lateral ventricles. Deep learning model We used state-of-the-art 3D self-...
NeuroMix always provided equivalent or better assessment of the brain parenchyma, with unique findings on NeuroMix and NeuroMix + MRA in 35% and 36% of cases, respectively, most commonly acute infarction or multiple microhemorrhages. In 8/174 cases (5%), CTAHN identified vascular abnormalities ...
As a result, patients with a BCVI are at risk of a secondary brain injury caused either by thrombo- embolism or occlusion of the artery [1–4]. Previously, BCVI was considered a rare cause of cerebral ischemia and ischemic stroke. Due to improved diagnos- tic imaging modalities, awareness...
The prior clinical course was mild, with slight join pain, chest discomfort, and nausea. She had no fever on admission (35.5 Celsius) and no respiratory symptoms. C-reactive protein was normal and interleukin (IL)-6 was elevated. CK was elevated, Hs-troponin T (640 ng/dL), and brain ...
A computed tomography of the head without contrast medium within 3 h after the onset of symptoms has a sensitivity of 47–53% and a specificity of 80% with regard to the presence of an acute ischemic stroke [10,11]. Severely affected patients should have standard CT or MRI imaging of ...
It’s simple: The human brain craves the familiar. We like what we already know. We develop skills based on repeated actions, and we eachbuild a repertoire of activitieswe can perform more or less automatically. Of course, it also has elasticity, meaning that we canlearn new things. In ...
Medium vessel occlusions (MeVOs) can be challenging to detect on imaging. Multiphase computed tomography angiography (mCTA) has been shown to improve large
