The ultrasound can be used primarily to guide exact needle placement for aspirations of fluids, injections of steroid, and biopsies in musculoskeletal field. Recently, ultrasound-guided intervention is widely used because of several advantages such as real-time performance, relatively inexpensiveness, and getting multiple images without additional radiations. However, the modality is operator dependent and requires detailed knowledge of the relevant anatomy and there have been also reported serious complications related to the procedure. So, authors will discuss about the basic techniques, principles and cautions for the use of ultrasound-guided intervention in musculoskeletal field.

In this study, we evaluated the thermal denaturation characteristics of reusable NIPAM tissue mimicking (TM) Phantom by measuring the thermal sensitivity. And the changes of acoustic characteristic and thermal denaturation shape in NIPAM TM phantom according to the number of re-use time and re-use period were observed. With the result, as the sonication time is increased, the sound velocity of NIPAM phantom was decreased by 100 m/s and the attenuation was increased slightly. However, the changes according to the re-use period was not observed. In the thermal denaturation shape and size observation by ultrasound sonicaton, the remarkable changes have not been confirmed. With the result of this study, NIPAM Phantom was considered appropriate to evaluate and predict the effect of therapeutic ultrasound by in repeated sonication test.

Ultrasonography is used for making the diagnosis and treatment decisions for those patients who complain of shoulder pain related with sports activity. Ultrasonography is especially helpful for diagnosing issues with the rotator cuff, the long head of biceps tendon and the acromio-clavicular joint. The medical decisions about shoulder pain can be promptly made when portable ultrasonography is used in the field of sports.

자궁경관 임신은 최근에 인공유산의 증가와 인공 보조 생식술(assisted reproductive technology) 등에 의하여 증가되는 양상을 보인다. 과거에는 자궁경관 임신은 대량의 무통성 질출혈로 진단을 내리고 치료 방법은 천자궁적출술이 유일한 수단이었으나, 지금은 질식 초음파의 개발로 자궁경관 임신을 조기에 진단하고 자궁 보존적 방법으로 치료하여 차후 임신을 기대할 수 있게 되었다. 그 치료 방법 중 하나로 Methotrexate(MTX)를 주사하여 성공적으로 치유된 많은 보고들이 있었다. 본 저자들은 임신 8주에 자궁경관 임신으로 진단된 환자에서 전신적 MTX 투여와 복식 초음파 관찰 하에 양막강내 MTX 투여 병합 요법으로 치료한 1례를 보고하고 치료과정에서 자궁경부 병변의 지연 관해에 대해서 문헌 고찰과 함께 보고하는 바이다.

Purpose: To evaluate the end results between the surgical treatment with neo-adjuvant chemotherapy in Korea and non-invasive high intensity focused ultrasound (HIFU) technique in China for osteogenic sarcomas. Materials and Methods: The surgical treatment with neoadjuvant chemotherapy for total 67 cases (4 IIA, 58 IIB, and 5 III) in Korea since 1993 and the HIFU therapy for total 71 cases (57 II and 14 III) in China since 1997 was performed. In Korea, neo-adjuvant chemotherapy in 66 cases out of total 67 patients, but the adjuvant chemotherapy in only one case was done. On the contrary, in China, full chemotherapy for more than 9 times for 37 patients with stage II out of total 71 cases, but for less than 8 times of partial chemotherapy for 23 patients (stage II) and 14 patients (stage III) was done. The surgical treatment in total 67 Korean patients was done with wide resection and reconstruction for 56 patients, but wide resection without reconstruction for 5 patients and amputation for 6 patients. In china, total 71 patients was treated with average 1.5 times (1~4 times) of HIFU, and if there are some evidences of residual tumor after HIFU with following MRI, the second HIFU therapy was given 2~4 weeks later. After then, the bony defect was in no touch, keep bracing for long time expecting regeneration. All of them were followed for average 46 Mo (12~150 Mo) in Korea, but followed for average 22 Mo (9 years~8 months) in China. Results: The 5 year survival rate (stage II), was average 92.7% (IIA 100%, IIB 85.5%) in Korea series, and average 78.7% (full chemotherapy 91.8%, part chemotherapy 56.6%) in China series. The 3 year survival rate (stage III) was 20% in Korea and 7.1% in China. So, the final overall survival rate was 65.2% in Korea and 51.8% in China. The overall functional outcome score by ISOLS was 24.3 (81%) in Korea and 19.8 (73%) in China. There are 25.4% (17/67 cases) of complications in Korea and 31% (27 complications in 22 patients out of total 71 cases) in China after each treatment. Conclusions: The end results of Korea series which was treated with neoadjuvant chemo- and surgical methods are better than that of non-invasive thermal ablation in china. But we also believe the HIFU, as one of, was also effective to decrease the local recurrence and symptomatic releaf for stage II or even in III of osteogenic sarcomas.

A 6-year-old, spayed female Cocker Spaniel was presented with generalized seborrhea sicca. Initially gallbladder mucocele (GM) was suggested by high liver enzyme activities and a stellate pattern in ultrasonography. There were no responses during 16 months of medical treatments for GM. Hormonal assay and histopathological findings were consistent with a diagnosis of hypothyroidism. Levothyroxine therapy led to rapid resolution of dermatologic, serum chemical and ultrasonographic abnormalities. This report describes serial changes of skin lesions, serum chemistry and ultrasonography in a dog with concurrent GM and hypothyroidism following treatment of hypothyroidism.

Acromioclavicular (AC) joint cyst is an uncommon presentation around the shoulder joint that is usually associated with chronic rotator cuff pathology and degenerative AC joint arthritis. Understanding the underlying pathophysiology of the shoulder joint is essential for appropriate interpretation of the AC joint cyst, assistance in determining the therapeutic strategy, and prevention of complications after treatment. We present a case of AC joint cyst with an aseptic fistula which was complicated by simple excision for recurred AC joint cyst after multiple aspirations. This case revealed a massive rotator cuff tear involving supraspinatus, infraspinatus, and subscapularis tendon on ultrasonography. We also reviewed the clinical approach and treatment options to be considered for its pathogenesis in the literature.

Purpose: The purpose of this study was to analyze the effectiveness of local steroid injection for infraspinatus under ultrasonographic guidance in patients with posterior shoulder pain during horizontal adduction test. Materials and Methods: Twenty one cases of patients, from May 2013 to May 2014, showed positive horizontal adduction test were retrospectively analyzed. We performed ultrasonography-guided infraspinatus injection using steroid to these patients in the outpatient clinics. We evalulated results for visual analogue score (VAS) for pain, UCLA score for these patients before injection, following 3 months and 6 months after injection. Results: After ultrasonography-guided infraspinatus injection using steroid, there were clinically significant improvements in VAS and UCLA score at 3 month's follow-up period (p<0.05). But there were no significant differences in VAS and UCLA score between 3 months and 6 months (p>0.05). Fourteen of 21 (67%) cases showed much improved and improved satisfaction. Respectively, seven of 21 (33%) cases showed not improved and aggravation satisfaction. Conclusion: Ultrasonography-guided infraspinatus injection using steroid is an effective treatment method for the patients with exacerbated posterior shoulder pain during horizontal adduction test.

Acupuncture is a treatment method that originated more than 3,000 years ago in China and is practiced in most of the world. Acupuncture became the most popular complementary and alternative medicine modality. Ultrasound is useful for research and educational purposes, visualizing needle insertion at acupuncture points, especially next to vulnerable structures such as nerves or the pleura. Additionally, ultrasound is an ideal imaging method for evaluation the biomechanical effects of needle manipulation on tissue and has the distinctive advantage of yielding both images of tissue morphology and biomechanical information. Elastography take aim at quantifying a mechanical response or the mechanical property of tissues from a mechanical stimulus, generated internally or externally. Therefore, the combination of ultrasound and elastography analyses allows quantitative assessment of dynamic changes in the structure of human connective tissue.
