Summary
T2 mapping accurately identifies long biceps tendon (LBT) pathologies by quantifying T2 values. This advanced MRI technique reliably distinguishes healthy tendons from those with tendinopathy, aiding early diagnosis and treatment.
Area of Science:
- Orthopedics
- Radiology
- Biomedical Imaging
Background:
- Shoulder discomfort often involves the long biceps tendon (LBT).
- Accurate diagnosis of LBT pathologies is crucial for effective treatment.
- Current diagnostic methods may have limitations in quantifying tendon integrity.
Purpose of the Study:
- To evaluate T2 mapping's ability to identify and quantify pathologies in the long biceps tendon (LBT).
- To compare T2 values in healthy versus pathological LBT.
- To determine the diagnostic accuracy of T2 mapping for LBT tendinopathy.
Main Methods:
- Eighteen patients with shoulder pain underwent MRI with T2 mapping, followed by arthroscopy.
- Regions of interest were placed on the LBT sulcus for T2 value quantification.
- Diagnostic cut-off values, sensitivity, specificity, and inter-reader correlation coefficients (ICCs) were calculated.
Main Results:
- Healthy LBTs had an average T2 value of 23.3 ± 4.6 ms; pathological LBTs averaged 47.9 ± 7.8 ms.
- A T2 value cut-off between 29.6 ms and 33.8 ms achieved 100% sensitivity and specificity.
- Inter-reader correlation coefficients (ICCs) ranged from 0.93 to 0.99, indicating high reliability.
Conclusions:
- T2 mapping effectively assesses and quantifies LBTs, distinguishing healthy from pathological states.
- This technique offers insights into the (ultra-)structural integrity of tendinous tissue.
- T2 mapping facilitates early diagnosis, treatment monitoring, and quantitative assessment of LBT conditions.
