Intraoperative Fast Adaptive Focus Tracking Robotic OCT Enables Real‐Time Tumor Grading and Large‐Area Microvascular Imaging in Human Spinal Cord Surgery

Advanced Science, EarlyView.
The fast adaptive focus tracking robotic optical coherence tomography (FACT‐ROCT) offers real‐time, high‐resolution imaging of spinal cord tumors during surgery. By reducing motion artifacts with robotics and adaptive focal tracking, it accurately differentiates tumor grades using a novel attenuation coefficient marker and reveals critical ...

Cerebrospinal fluid biomarkers of superficial siderosis in patients with spontaneous intracranial hypotension

European Journal of Neurology, Volume 30, Issue 1, Page 235-240, January 2023., 2023
Cerebrospinal fluid (CSF) alterations indicative of infratentorial superficial siderosis are prevalent amongst patients with SIH. It is speculated that a preclinical phase without symptoms or imaging signs but during which elevated biomarkers of the disease are apparent from CSF analysis might exist.

Risk Factors and Predictive Model for Ischemic Complications in Endovascular Treatment of Intracranial Aneurysms: Insights From a Large Patient Cohort

AGING MEDICINE, EarlyView.
Independent risk factors for ischemic complications in endovascular treatment of intracranial aneurysms were identified using machine learning methods, and the first prediction model for ischemic complications of all intracranial aneurysms was constructed. Moreover, the model showed a stable and excellent predictive efficacy.

The location of intraparenchymal bleeding determines functional outcome after spontaneous subarachnoid hemorrhage

European Journal of Neurology, Volume 30, Issue 2, Page 372-379, February 2023., 2023
Subarachnoid hemorrhage patients with hemorrhagic lesions of the corpus callosum (n = 6/280) are at an elevated risk of unfavorable 3‐month functional outcome. Abstract Background and purpose Non‐traumatic subarachnoid hemorrhage (SAH) is a devastating disease associated with high morbidity and mortality.

An Automatic Detection Method Of Cerebral Aneurysms In Time-Of-Flight Magnetic Resonance Angiography Images Based On Attention 3D U-Net [PDF]

arXiv, 2021
Background:Subarachnoid hemorrhage caused by ruptured cerebral aneurysm often leads to fatal consequences.However,if the aneurysm can be found and treated during asymptomatic periods,the probability of rupture can be greatly reduced.At present,time-of-flight magnetic resonance angiography is one of the most commonly used non-invasive screening ...

Improvement of Automatic Hemorrhages Detection Methods Using Shapes Recognition [PDF]

Journal of Computer Science 9 (9): 1205-1210, 2013, 2013
Diabetic Retinopathy is a medical condition where the retina is damaged because fluid leaks from blood vessels into the retina. The presence of hemorrhages in the retina is the earliest symptom of diabetic retinopathy. The number and shape of hemorrhages is used to indicate the severity of the disease.

Unmasking a subarachnoid hemorrhage [PDF]

Neurology, 2013
A 53-year-old patient presented with acute headache. CT and intra/extracranial CT angiography were normal. A traumatic lumbar puncture showed 8,500 erythrocytes/mm3 and 24 leukocytes/mm3. MRI showed extensive sulcal fluid-attenuated inversion recovery (FLAIR) hyperintensities suggesting subarachnoid hemorrhage (figure).

Small intracranial aneurysms of the anterior circulation: A negligible risk?

European Journal of Neurology, Volume 30, Issue 2, Page 389-398, February 2023., 2023
Abstract Background and purpose According to the International Study of Unruptured Intracranial Aneurysms, small (<7 mm) unruptured intracranial aneurysms (IAs) of the anterior circulation (aC) carry a neglectable 5‐year rupture risk. In contrast, some studies report frequencies of >20% of all ruptured IAs being small IAs of the aC.
