Diagnostic performance of fluoroscopic video analysis for pulmonary embolism: a prospective observational study.
Int J Cardiovasc Imaging
July 2024
Department of Cardiology and Nephrology, Mie University Graduate School of Medicine, 2-174 Edobashi, Tsu, Mie, 514-8507, Japan.
Purpose: Dynamic chest radiography using X-ray fluoroscopic video analysis has shown potential for the diagnosis of pulmonary embolism (PE), but its diagnostic performance remains uncertain. We aimed to evaluate the diagnostic performance of fluoroscopic video analysis for diagnosing PE.
Methods: A prospective single-center observational study was conducted between October 2020 and January 2022.
Apnea behavior in early- and late-stage mouse models of Parkinson's disease: Cineradiographic analysis of spontaneous breathing, acute stress, and swallowing.

This study aimed to evaluate the timing and frequency of spontaneous apneas during breathing and swallowing by using cineradiography on mouse models of early/initial or late/advanced Parkinson's disease (PD). C57BL/6 J mice received either 6-OHDA or vehicle injections into their right striatum, followed by respiratory movement recordings during spontaneous breathing and swallowing, and a stress challenge, two weeks later. Experimental group animals showed a significantly lower respiratory rate (158.

Objective Radwisp™ is a fluoroscopic video analysis workstation recently developed to evaluate pulmonary circulation, thereby obviating the need for contrast medium or breath-holding. This study validated Radwisp as a diagnostic tool for acute pulmonary embolism (APE) and evaluated its potential utility in patients with symptoms of suspected APE. Methods The study included 10 patients (mean age, 69±16 years old) who were admitted to our hospital for suspected APE based on symptoms and physical examination findings between January 2020 and April 2021.

Annu Int Conf IEEE Eng Med Biol Soc

Article Synopsis
- Every year, new cases of traumatic spinal injuries are reported, and while advances in numerical models help understand the damage, the details of vertebral fracture formation and fragment propulsion are still unclear due to a lack of data.
- Researchers addressed this gap by analyzing X-Ray images of animal specimens to develop a method for automatically detecting and tracking vertebral fractures using high-speed cine-radiography imaging.
- The study demonstrated the effectiveness of this approach, providing valuable insights that could aid in the treatment and management of traumatic spinal injuries.
