Tomosynthesis of the Wrist and Hand in Patients With Rheumatoid Arthritis: Comparison With Radiography and MRI

Abstract

Tomosynthesis is superior to radiography and almost comparable to MRI for the detection of bone erosion in patients with RA.

The value of X‑ray digital tomosynthesis in the diagnosis of urinary calculi

“…The development of digital tomosynthesis (DTS) has received a lot of attention as it administers a low dose of radiation and has a high resolution (7)(8)(9)(10). DTS technology is widely used within dentistry and orthopedics as well as in the imaging of the breast, chest and blood vessels (11,12). However, few studies have been performed to assess the application of DTS on the gastrointestinal and urinary tracts.…”

Tomosynthesis of the thoracic spine: added value in diagnosing vertebral fractures in the elderly

“…It has also been used for evaluation of fracture healing [15], with similar results. In peripheral arthritis imaging, it has been shown to be better than radiography but not as good as CT [16] but almost as good as MRI in detecting erosions [17]. Digital linear tomosynthesis in musculoskeletal applications should not be seen as a tool to replace CT, but as an improvement on radiography to provide better imaging at low cost and low added dose.…”

Tomosynthesis can facilitate accurate measurement of joint space width under the condition of the oblique incidence of X-rays in patients with rheumatoid arthritis

“…CT is used for more accurate evaluation of joint destruction but has disadvantages such as high exposure of radiation. [6][7][8] CT, therefore, is not a first-line examination, and although the continued use of radiographs in RA is debated, it is still recommended to acquire a baseline radiograph. Because tomosynthesis, a recently developed modality, is superior to radiography for the evaluation of overlapping structure such as intercarpal joints with lower radiation exposure than CT, it is expected to be applied to joint destruction evaluation, [9][10][11][12] although the accuracy of measurement of JSN with tomosynthesis has not yet been validated.…”
