Abstract: • High-bandwidth TSE and compressed sensing SEMAC improve MRI of ankle arthroplasty implants. • Compressed sensing SEMAC improves bone-implant interfaces, periprosthetic bone, tendons and joint capsule visibility. • Compressed sensing SEMAC improves the diagnosis of osteolysis, tendinopathy, fractures and synovitis. • MRI decreases the number of clinical differential diagnoses of painful ankle arthroplasty implants.

“…On phantom scans, the overall extent of artifacts was small in all acquired CS-SEMAC sequences, which is consistent with previous observations. 10,13,17,36 Residual ripple artifacts were already described as typical artifacts induced by SEMAC sequences. 10,19 We could demonstrate that ripple artifacts increased with more SESs and iterations.…”

“…The issue of reconstruction time, computation power, and processor speed has not been discussed so far. 10,11,13,17 More iterations were associated with reduced metal artifacts and reduced blurring, but also with more severe ripple artifacts and longer reconstruction times. None of the parameters improved significantly with application of 30 or 50 iterations as compared with 20 iterations.…”

“…This technique was combined successfully with both MAV-RIC 33 and SEMAC. [34][35][36][37] With preserved image quality, SEMAC has gained an eightfold acceleration by exploiting all synergies between parallel imaging and CS, resulting in acquisition times that are similar to those of turbo spin-echo pulse sequences [34][35][36][37] (►Fig. 9).…”

“…They found that CS-SEMAC significantly improved detection and diagnostic confidence in the detection of periprosthetic marrow edema, osteolysis, and fractures, as well as synovitis and tendinopathy. 112 These techniques, either in combination with or instead of existing FSE sequences, may help establish a larger future role for MRI in assessing painful TAAs.…”
