“…9). 32,33 ZTE appeared blurrier in cortical bone than CT in severe spondylolysis cases. However, ZTE could offer more cortical bone details than conventional MRI and osseous parameters (eg, axial orientation, interarticular distance, foramina diameter, pedicle width, facet joint OA grade) between ZTE and CT are reported to be comparable.…”

Zero echo time (ZTE) sequence is recent advanced magnetic resonance technique that utilizes ultrafast readouts to capture signals from short‐T2 tissues. This sequence enables T2‐ and T2* weighted imaging of tissues with short intrinsic relaxation times by using an extremely short TE, and are increasingly used in the musculoskeletal system. We review the imaging physics of these sequences, practical limitations, and image reconstruction, and then discuss the clinical utilities in various disorders of the musculoskeletal system. ZTE can be readily incorporated into the clinical workflow, and is a promising technique to avoid unnecessary radiation exposure, cost, and time‐consuming by computed tomography in some cases.Level of Evidence4Technical EfficacyStage 1

“…High intermodality and interrater agreement between ZTE MRI and CT were also found when evaluating cervical neuroforaminal stenosis 80 (Fig. 16), lumbar degenerative changes, 81 and sacroiliac joint structural lesions 82 . In addition, ZTE MRI can be used to evaluate ossification of the posterior longitudinal ligament of the spine 83,84 (Fig.…”

Repeated computed tomography (CT) examinations increase patients' ionizing radiation exposure and health costs, making an alternative method desirable. Cortical and trabecular bone, however, have short T2 relaxation times, causing low signal intensity on conventional magnetic resonance (MR) sequences. Different techniques are available to create a “CT-like” contrast of bone, such as ultrashort echo time, zero echo time, gradient-echo, and susceptibility-weighted image MR sequences, and artificial intelligence. This systematic review summarizes the essential technical background and developments of ultrashort echo time, zero echo time, gradient-echo, susceptibility-weighted image MR imaging sequences and artificial intelligence; presents studies on research and clinical applications of “CT-like” MR imaging; and describes their main advantages and limitations. We also discuss future opportunities in research, which patients would benefit the most, the most appropriate situations for using the technique, and the potential to replace CT in the clinical workflow.

“…Recently, new MRI sequences have become available that may allow for accurate cortical and trabecular bone assessment. ZTE (zero echo time) [5][6][7] and UTE (ultrashort echo time) [8][9][10][11] MRI sequences belong to a group of novel 3D MRI pulse sequences that use an echo time (TE) of 1 ms or less enabling the acquisition of sufficient signal from rapidly decaying short-T2 tissue components which are abundant in calcified cartilage such as at the transition of articular cartilage to the subchondral bone, tendons, and menisci (Fig. 1) [12][13][14].…”

“…In particular, in these short echo time sequences, signal can be provided from short T2 tissues to provide a contrast mechanism that affords visualization of the cortical bone of the SI joint [5,6,12]. Importantly, ZTE and UTE feature comparable contrast-to-noise and signal-to-noise ratios (CNR/SNR) [15].…”

Objectives To compare the value of zero echo time (ZTE) and gradient echo “black bone” (BB) MRI sequences for bone assessment of the sacroiliac joint (SI) using computed tomography (CT) as the reference standard. Materials and methods Between May 2019 and January 2021, 79 patients prospectively underwent clinically indicated 3-T MRI including ZTE and BB imaging. Additionally, all patients underwent a CT scan covering the SI joints within 12 months of the MRI examination. Two blinded readers performed bone assessment by grading each side of each SI joint qualitatively in terms of seven features (osteophytes, subchondral sclerosis, erosions, ankylosis, joint irregularity, joint widening, and gas in the SI joint) using a 4-point Likert scale (0 = no changes–3 = marked changes). Scores were compared between all three imaging modalities. Results Interreader agreement was largely good (k values: 0.5–0.83). Except for the feature “gas in SI joint” where ZTE exhibited significantly lower scores than CT (p < 0.001), ZTE and BB showed similar performance relative to CT for all other features (p > 0.52) with inter-modality agreement being substantial to almost perfect (Krippendorff’s alpha coefficients: 0.724–0.983). When combining the data from all features except for gas in the SI joint and when binarizing grading scores, combined sensitivity/specificity was 76.7%/98.6% for ZTE and 80.8%/99.1% for BB, respectively, compared to CT. Conclusions The performance of ZTE and BB sequences was comparable to CT for bone assessment of the SI joint. These sequences may potentially serve as an alternative to CT yet without involving exposure to ionizing radiation.
