A comparison of three-dimensional ultrasound, two-dimensional ultrasound and dissections for determination of lesion volume in tendons.
Abstract: The purpose of this work was to evaluate the accuracy and precision of a freehand three-dimensional (3-D) ultrasonography system in the determination of lesion volume in tendons. The accuracy and precision of a 3-D ultrasonography system was assessed by performing repeated measurements on a phantom of known volume. Volume measurements of tendon lesions performed with 3-D ultrasonography were compared with measurements based on a series of two-dimensional (2-D) ultrasound (US) scans and to direct measurements from dissections. A novel method for the creation of tendon lesions in vitro was developed. 3-D US showed excellent precision and accuracy in measurements of the phantom (mean measured volume = 3.76 mL, calculated volume = 3.77 mL, coefficient of variation (CoV) = 0.54%) and good repeatability in the determination of tendon lesions (repeatability coefficient = 0.00047). All three methods examined were repeatable (repeatability coefficient for 2-D US = 0.00032, repeatability coefficient for dissections = 0.00076). However, each of the methods produced different results and no constant relationship could be found between any of the measurement methods. Both 3-D and 2-D US proved to be repeatable techniques for the measurement of the volume of a tendon lesion. Even if they produced different results, each of them can be repeatedly used individually. It was not possible to define which one provided the most accurate value as a result of difficulties encountered in lesion identification on histology, and therefore the lack of a gold standard.

This study compared the accuracy and preciseness of three-dimensional ultrasound, two-dimensional ultrasound, and dissections in determining the lesion volume in tendons. It found that both ultrasounds are repeatable techniques, yet all methods produced different results, making it hard to determine which was the most accurate.
Methods
- The researchers carried out their study by evaluating a freehand 3-D ultrasonography system’s precision and accuracy in calculating tendon lesion volume. They did this by conducting repeated measurements on a phantom (a sample object) of known volume.
- 3-D ultrasound measurements of tendon lesions were compared to measurements obtained from a series of 2-D ultrasounds and direct measurements from dissections to form a comparative basis.
- The researchers developed a new method for creating tendon lesions in vitro, which allowed for this examination.
Results
- The 3-D ultrasonography system showed excellent precision and accuracy in phantom measurements (mean measured volume was 3.76 mL, and the calculated volume was 3.77 mL, with a coefficient of variation of 0.54%). It also portrayed good repeatability in identifying tendon lesions.
- All three methods – the 3-D ultrasound, the 2-D ultrasound, and dissection – exhibited repeatability in their results.
- Despite repeatability, each method produced varying results and no continuous connection could be established between any of the measurement techniques tested.
Conclusions
- Both the 3-D and 2-D ultrasounds were confirmed to be dependable techniques for the measurement of tendon lesion volumes, although they produced differing data.
- Due to issues with lesion identification in histology, no definitive ruling could be made on which of the three methods provided the most accurate value.
- Despite the differences in results, each method can be used repeatedly on its own due to their confirmed repeatability.
