Five Numerical Methods to Assess the Ischemic Risks in Dental Pulp and Neuro-Vascular Bundle Under Orthodontic Movements in Intact Periodontium In Vitro.
Dent J (Basel)
December 2024
Department of Cariology, Endodontics and Oral Pathology, School of Dental Medicine, University of Medicine and Pharmacy Iuliu Hatieganu, Str. Motilor 33, 400001 Cluj-Napoca, Romania.
: Dental pulp and its neuro-vascular bundle (NVB) are among the least studied dental tissues. This study identified the best method for evaluating ischemic risks in the dental pulp and NVB of healthy lower premolars under orthodontic forces and in intact periodontium. : Nine 3D models of the second lower premolar were reconstructed based on the CBCT scans from nine patients.

Objective: This prospective observational study aimed to assess the effectiveness of B-mode ultrasound, color-coded Doppler, and shear-wave elastography in predicting intracranial pressure (ICP) and their capability to evaluate the efficacy of ICP lowering therapy.
Materials And Methods: Forty-eight neuro-critical care patients were enrolled and categorized into 2 groups based on ICP measurements obtained through external ventricular drainage: the intracranial hypertension (IH) and normal ICP groups. The optic nerve (ON) sheath diameter (ONSD), end diastolic velocity, peak systolic velocity, resistance index of the central retinal artery (CRA), and Young's modulus (YM) of the ON were recorded after external ventricular drainage placement and following ICP lowering treatment in the IH group.
Clinical study of colorViz fusion image vascular grading based on multi-phase CTA reconstruction in acute ischemic stroke.
BMC Med Imaging
January 2025
Department of Intervention, The First Affiliated Hospital of China Medical University,No.155 The Nanjing North street, Heping District, Shenyang, Liaoning, 110000, P.R. China.
Objective: This study aimed to evaluate the diagnostic value of ColorViz fused images from multi-phase computed tomography angiography (mCTA) using GE Healthcare's FastStroke software for newly diagnosed cerebral infarctions in patients with acute ischemic stroke (AIS).
Methods: A total of 106 AIS patients with unilateral anterior circulation occlusion were prospectively enrolled. All patients underwent mCTA scans during the arterial peak phase, venous peak phase, and venous late phase.
Bone mass distribution of 892 distal tibiae and implications for the treatment of medial malleolar fractures.
Foot Ankle Surg
January 2025
Department of Trauma and Orthopaedic Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.
Background: The medial malleolus is involved in up to 50 % of ankle fractures. When surgery is required, a thorough understanding of bone mass distribution within the distal tibia is crucial for selecting and positioning screws to ensure stable fixation. Despite its clinical significance, data on the bone mass distribution in the distal tibia remains limited.

Medical school, Kunming University of Science and Technology, Kunming, Yunnan, China.
Objective: In-depth investigation of the diagnostic performance of dual-energy CT (DECT) virtual non-calcium (VNCa) technique for sacroiliac joint bone marrow edema (BME) in patients with ankylosing spondylitis(AS).
Methods: A total of 42 patients with AS)who underwent sacroiliac joint MRI and DECT scans on the same day at our Rheumatology and Immunology Department between August 2022 and June 2023 were selected. Using MRI as the reference standard, the presence of BME on the iliac and sacral surfaces was evaluated, resulting in the categorization of patients into BME-positive and BME-negative groups.
