1/ SWE and ARFI for Rotator Cuff Supraspinatus Tendon: A preliminary experience.
Hung Thien Nguyen – Kien Trong Phung - Hai Thanh Phan, MEDIC MEDICAL CENTER HCMC, Vietnam / ACCEPTED

ABSTRACT:
 

Purpose: Partial and complete thickness rotator cuff tears are a musculoskeletal condition  and conventional ultrasound plays a role in diagnosing and follow-up this condition with a high sensibility and specificity. The aim of this study is to investigate the stiffness of torn site and fibrosis site of rotator cuff supraspinalis tendon.

Materials and Methods: 49 patients were enrolled in the study with written consent and  our study was allowed to perform by the Ethnics Commitee of our institution. All of them went through elastographic ultrasound examination by SWE (Supersonic Imagine) and ARFI (Siemens S2000) techniques.

Results and Discussions: There were 19 cases of intact  rotator cuff supraspinatus tendon, 15 cases of torn supraspinatus tendon and 15 cases of fibrosis ones. Values of SWE velocity were of 22.10+/- 4.06 kPa, of 35.39+/-5.30 kPa and of 62.70+/-11.29kPa, respectively. There was a significant statistical difference of torn and fibrosis groups (p <. 0001).
Elastograms with colored code show black color on ARFI technique (hard) or red color (hard) on SWE technique.





Conclusions: Elastographic ultrasound (SWE and ARFI) detected qualitatively stiff areas of abnormal supraspinatus tendon, but ARFI values tend to be over the limit of measurement of ultrasound system (Siemens S2000).

 2/  Acoustic Radiation Force Impulse (ARFI) Imaging of Thyroid Nodules,
Vo Mai Khanh, Nguyen Thien Hung, Phan Thanh Hai, MEDIC MEDICAL CENTER, HCMC, Vietnam/ ACCEPTED
ABSTRACT:

Purpose:
 The aim of the present study was to evaluate the feasibility of ARFI-measurements in combining of VTI in the thyroid nodule.

Methods and materials:
 All patients underwent conventional ultrasound, ARFI-imaging and cytological assessment. ARFI-imaging (VTI and VTQ technology) were performed with 9L4 probe, using Siemens (ACUSON S2000) B-mode-ARFI combination transducer. 

Results and discussions:
 130 nodules were available for analysis. 103 nodules were benign on cytology, 20 nodules were malignant ( papillary carcinomas), and 7 follicular lesions. The average velocity of ARFI-imaging in benign and malignant thyroid nodules was of 2.4 m/s,  and of 3.2 m/s, respectively. A sensitivity of 79.4% and specificity  of 53.7% of ARFI-imaging could be achieved using a cut-off of 2.16 m/s (area under ROC curve is 0.731, p < 0.0001).
Conclusions:
 ARFI can be performed in thyroid nodule with reliable results. ARFI might be the reference criteria for differentiation of benign and malignant thyroid nodules.
