2025年3月4日 · Subdural hemorrhage/hematoma (SDH) is a collection of blood accumulating in the subdural space. Subdural hemorrhage can happen in any age group, is mainly due to head trauma and CT scans are usually sufficient to make the diagnosis. Prognosis varies widely depending on the size and chronicity of the hemorrhage.

This study demonstrates the high performance of a fully automated, deep learning algorithm for detection and quantification of IPH, EDH/SDH, and SAH on NCCT examinations of the head. Furthermore, confirmation of high algorithm performance on a prospectively acquired, independent test set while embedded in an automated inference environment ...

美国德克萨斯大学放射科的Marco Colasurdo等针对NCCT影像中检测和量化硬膜下血肿的问题，开发出一种新的卷积神经网络（Viz.ai SDH CNN），结果在线发表于2022年9月的《Journal of Neurosurgery》上。

2019年4月29日 · Acute subdural hemorrhage (SDH) is commonly encountered by emergency radiologists in the setting of trauma. When history or imaging evidence of trauma is absent, the differential diagnosis for SDH should be expanded. Intracranial aneurysm rupture is a rare and underrecognized cause of SDH which may present without concurrent subarachnoid ...

Acute Subdural hematoma (ASDH) is a form of traumatic brain injury in which blood gathers between dura and the arachnoid membrane. It occurs in approximately 15% of all 1, 2 traumatic brain injuries and in 30% of the severe ones . Acute subdural haematoma may be …

2023年6月1日 · Non-contrast computed tomography (NCCT) scan is the most appropriate initial neuroimaging examination for TBI patients. About 90% of the patients with TBI were examined by NCCT at the time of initial admission. Moreover, a second scan is recommended to observe the changes of the lesions within several days [12]. Radiomics can use mathematical ...

Post traumatic hydrocephalus (PTH) is a commonest treatable complication of severe traumatic brain injury that’s leads to failure of improvement and worsening of the...

2025年2月28日 · Here, we describe 3 chronic subdural hematomas, 1 of which showed enhancement after middle meningeal artery embolization and 2 of which enhanced after contrast-enhanced CT (CECT) for additional imaging of the head or body. These collections all then rapidly resolved their enhancement on additional follow-up imaging.

NCCT of the head (postoperative): evidence of right lateral supraorbital craniotomy and clip artifact. No evidence of EDH/hematoma/ventriculomegaly seen ( ).

2022年9月30日 · Subdural hemorrhage (SDH) is a collection of blood between the dura and the arachnoid layers of the meninges. They are common and can occur in any age range, usually related to a history of head trauma. Prognosis tends to depend on the extent of the bleed and associated mass effect.
