Contrast-enhanced pseudo-CT of finger joints: Improved diagnostic confidence for detection of inflammatory erosions.
Eur J Radiol
December 2024
Radiology, Balgrist University Hospital, Forchstrasse 340, 8008 Zurich, Switzerland; Faculty of Medicine, University of Zurich, Zurich, Switzerland.
Purpose: To evaluate the interest of additional pseudo-CT images to standard clinical contrast-enhanced MR images (CE-MRI) in the detection of inflammatory erosions and to differentiate them from intraosseous ganglia at the finger joints.
Method: 47 prospectively included patients with suspected or diagnosed rheumatoid arthritis received a CE-MRI of the fingers. Additionally, pseudo-CT images were derived from non-contrast MRI (pCT) and from contrast-enhanced MRI data (CE-pCT) using a high-resolution gradient-echo 3D fast low-angle shot sequence (FLASH), respectively.

Background: Numerous techniques for arthrodesis have been described to fix interphalangeal (IP) joints, and the fixation method should be considered on a case-by-case basis. This study aimed to investigate the availability of IP joint arthrodesis of the hand, using a two-dimensional intraosseous wiring (two-DIOW) method.
Methods: A total of 43 joints (19 thumb IP joints, 9 proximal finger interphalangeal (PIP) joints and 15 distal interphalangeal (DIP) joints in 29 patients with a mean age of 66 years (range, 24-85 y) were retrospectively analyzed.
