292. Improved Processing for Dual-Energy Subtraction in Computed Radiography

Improved detection of an intravascular catheter using dual energy subtraction radiography

A 68 year old woman was admitted for discitis and required subsequent antimicrobial therapy, necessitating placement of a 35 cm right-sided peripherally-inserted central catheter into the superior vena cava under ultrasound and fluoroscopic guidance. Eleven months after intial placement of the catheter, the patient was admitted for pneumonia. At that time, a posteroanterior dual energy chest ra...

New computed radiography processing condition for whole-spine radiography.

Computed radiography (CR) has many advantages compared with conventional radiographs, especially in image processing. Although CR is being used in chest radiography and mammography, it has not been applied to spine imaging. The purposes of this study were to formulate a set of new CR processing parameters and to test whether the resultant whole-spine radiographs visualized the spine more clearl...

Dual-Energy Subtraction Imaging for Diagnosing Vocal Cord Paralysis with Flat Panel Detector Radiography

OBJECTIVE To investigate the clinical feasibility of dual energy subtraction (DES) imaging to improve the delineation of the vocal cord and diagnostic accuracy of vocal cord paralysis as compared with the anterior-posterior view of flat panel detector (FPD) neck radiography. MATERIALS AND METHODS For 122 consecutive patients who underwent both a flexible laryngoscopy and conventional/DES FPD ...

Optimal speed for dual-energy subtraction neck imaging with flat-panel detector radiography

Diagnostic accuracy and added value of dual-energy subtraction radiography compared to standard conventional radiography using computed tomography as standard of reference

PURPOSE To retrospectively evaluate diagnostic performance of dual-energy subtraction radiography (DESR) for interpretation of chest radiographs compared to conventional radiography (CR) using computed tomography (CT) as standard of reference. MATERIAL AND METHODS A total of 199 patients (75 female, median age 67) were included in this institutional review board (IRB)-approved clinical trial....
