Fig 2.
(A) A 5 mm circular ROI was placed at the thenar muscle and the 2nd metacarpal base in axial fat-suppressed image. (B) For coronal images, the 1st interosseous muscle and 2nd metacarpal base of the same image plane were selected.
Fig 3.
An 80-year-old female with a distal radius fracture. Coronal PD-weighted TSEDL image with fat suppression showed grid artifact (arrows), which was defined as a pattern of lines that cross each other to form squares on the image.

A 57-year-old female with a distal radius fracture.
(A) Axial T2-weighted TSES image with fat suppression and (B) the corresponding TSEDL image. TSEDL images showed superior rSNR, rCNR and rCR compared to TSES images.
Fig 5.
A 57-year-old female with a distal radius fracture.
(A) Coronal T1-weighted TSES image and (B) the corresponding TSEDL image. TSEDL images showed superior rSNR, rCNR and rCR compared to TSES images.

A 57-year-old female with a distal radius fracture.
(A) PD-weighted TSES image with fat suppression and (B) the corresponding TSEDL image. TSEDL images showed superior rSNR, rCNR and rCR compared to TSES images.

Fig 7.
(A) Coronal T1-weighted TSES image of a 70-year-old female patient revealed severe margin blurring of the bone and joint by motion artifact (arrowheads). (B) In contrast, sharp-edged anatomic details were noted without motion artifacts in the corresponding TSEDL image.
Fig 8.
Associated ulnar styloid process fracture.
(A) Coronal T1-weighted TSES image of a 60-year-old female with a distal radius fracture demonstrated suspected fragmentation of the ulnar styloid process with indistinct cortices. (B) However, a small bony fragment with distinct cortices and internal fatty marrow was well delineated on the corresponding TSEDL image. (C) Coronal CT image clearly showed ulnar styloid process fracture with bone fragments.
Fig 9.
Associated triangular fibrocartilage complex injury.
(A) On coronal fat-suppressed PD-weighted TSES image of an 86-year-old female with distal radius and ulnar fractures, wavy radial attachment (arrow) of the disc was seen with blurred margin and internal signal alteration. (B) In contrast, the TSEDL image showed a sharp margin of the disc with localized signal alteration of the radial attachment (arrow). Nearby lunate articular cartilage and ulnar cortical fragments were clearly delineated as well.
