Dual-energy CT arthrography: a feasibility study

| description | Objective
To evaluate the feasibility of producing 2-dimensional (2D) virtual noncontrast images and 3-dimensional (3D) bone models from dual-energy computed tomography (DECT) arthrograms and to determine whether this is best accomplished using 190 keV virtual monoenergetic images (VMI) or virtual unenhanced (VUE) images.
Materials and methods
VMI and VUE images were retrospectively reconstructed from patients with internal derangement of the shoulder or knee joint who underwent DECT arthrography between September 2017 and August 2019. A region of interest was placed in the area of brightest contrast, and the mean attenuation (in Hounsfield units [HUs]) was recorded. Two blinded musculoskeletal radiologists qualitatively graded the 2D images and 3D models using scores ranging from 0 to 3 (0 considered optimal).
Results
Twenty-six patients (mean age ± SD, 57.5 ± 16.8 years; 6 women) were included in the study. The contrast attenuation on VUE images (overall mean ± SD, 10.5 ± 16.4 HU; knee, 19.3 ± 10.7 HU; shoulder, 5.0 ± 17.2 HU) was significantly lower (

p

Conclusions
DECT arthrography can be used to produce 2D virtual noncontrast images and to generate 3D bone models. The VUE technique is superior to VMI in producing virtual noncontrast images.</description><identifier>ISSN: 0364-2348</identifier><identifier>EISSN: 1432-2161</identifier><identifier>DOI: 10.1007/s00256-020-03603-9</identifier><identifier>PMID: 32948903</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Attenuation ; Computed tomography ; CT imaging ; Diagnostic imaging ; Feasibility studies ; Image contrast ; Image reconstruction ; Imaging ; Knee ; Medical imaging ; Medicine ; Medicine & Public Health ; Nuclear Medicine ; Orthopedics ; Pathology ; Radiology ; Scientific Article ; Shoulder ; Three dimensional models ; Two dimensional models</subject><ispartof>Skeletal radiology, 2021-04, Vol.50 (4), p.693-703</ispartof><rights>ISS 2020</rights><rights>COPYRIGHT 2021 Springer</rights><rights>ISS 2020.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c442t-1ee056a9b5ffcd338f4a46a0af791efdfddffd5fa0e2a02ae1aee0facdf3cf963</citedby><cites>FETCH-LOGICAL-c442t-1ee056a9b5ffcd338f4a46a0af791efdfddffd5fa0e2a02ae1aee0facdf3cf963</cites><orcidid>0000-0002-0502-6280</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00256-020-03603-9$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00256-020-03603-9$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,780,784,27923,27924,41487,42556,51318</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/32948903$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Sandhu, Rashpal</creatorcontrib><creatorcontrib>Aslan, Mercan</creatorcontrib><creatorcontrib>Obuchowski, Nancy</creatorcontrib><creatorcontrib>Primak, Andrew</creatorcontrib><creatorcontrib>Karim, Wadih</creatorcontrib><creatorcontrib>Subhas, Naveen</creatorcontrib><title>Dual-energy CT arthrography: a feasibility study</title><title>Skeletal radiology</title><addtitle>Skeletal Radiol</addtitle><addtitle>Skeletal Radiol</addtitle><description>Objective
