AI Article Synopsis
- Zero echo time (ZTE) is a new MRI technique that captures high-quality images of tissues with short relaxation times, improving the diagnosis of musculoskeletal disorders.
- The article reviews the imaging physics behind ZTE, its challenges, and how images are reconstructed for clinical use.
- ZTE offers a radiation-free alternative to CT scans, potentially saving costs and time in the imaging process.
Article Abstract
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 EVIDENCE: 4 TECHNICAL EFFICACY: Stage 1.
