OBJECTIVE: To examine dual-energy computed tomography (DECT) in evaluating cruciate @entity130 . More specifically, the purpose was to assess the optimal keV level in DECT gemstone spectral imaging (GSI) images and to examine the usefulness of collagen-specific color mapping and dual-energy bone removal in the evaluation of cruciate ligaments and the popliteus tendon. MATERIALS AND METHODS: At a level 1 @entity130 center, a 29-month period of emergency department DECT examinations for @entity697 was reviewed by two radiologists for presence of cruciate @entity130 , visualization of the popliteus tendon and the optimal keV level in GSI images. Three different evaluating protocols (GSI, bone removal and collagen-specific color mapping) were rated. Subsequent MRI served as a reference standard for intraarticular injuries. RESULTS: A total of 18 @entity1 who had an @entity697 , DECT and MRI were found. On MRI, six @entity1 had an @entity397 . DECT's sensitivity and specificity to detect @entity397 were 79  % and 100  %, respectively. The DECT vs. MRI intra- and interobserver proportions of agreement for @entity397 were excellent or good (kappa values 0.72-0.87). Only one @entity1 had a @entity397 . In GSI images, the optimal keV level was 63  keV. GSI of 40-140  keV was considered to be the best evaluation protocol in the majority of cases. CONCLUSION: DECT is a usable method to evaluate ACL in @entity697 @entity1 with rather good sensitivity and high specificity. GSI is generally a better evaluation protocol than bone removal or collagen-specific color mapping in the evaluation of cruciate ligaments and popliteus tendon.
