This study aims to comparison of ultrasonography on both sides of the upper arm of hemiplegic patient. The biceps brachii and deltoid muscle of ten subjects(4 men, 6 women) with stroke were scanned with ultrasonography at the muscle belly at rest at elbow angles of 90 deg. The echogenicity(densit, white area index; WAI) and muscle thickness of ultrasonography was examined using real-time B-mode ultrasonography with 7.5 MHz linear-array prob. In the biceps brachii muscle, MHz there were significant differences of thickness, density, and WAI between affected side and non-affected side. In the deltoid muscle, there were significant differences of thickness, density, and WAI between affected side and non-affected side. Both of the muscles, thickness of the affected side was thin than non-affected side and echogenicity(density, WAI) of the affected side was higher than non-affected side. This study showed that change of skeletal muscle architecture properties occurred in the upper arm of the affected side muscle of hemiplegic patient.

The purpose of this article is review about the use of ultrasonography in the evaluation of the elbow joint. Ultrasonography has several key advantages in elbow joint, including easy assessment of target structure in elbow joint and ability to perform real time dynamic examination and to compare with opposite site. Ultrasonography is easy available to visualize abnormalities affecting tendons, muscles, ligaments, bursae, and occult fractures around the elbow joint and also allows accurate assessment of ulnar nerve in cubital tunnel. The role of ultrasonography will increase further with regards to evaluation of soft-tissue abnormalities of the elbow joint.

Simple radiography, CT and MRI were used for the diagnosis of the hip disease. However ultrasonography could be a good diagnostic tool for the lesion of tendons and bursae. Another advantage of ultrasonography is its usefulness for the follow-up of these lesions. Nowadays hip ultrasonography expanded the horizon to the follow-up study of total hip arthroplasty. However, the limitation of ultrasonography is that there is disparity in results according to the physician's experiences. In this article ultrasonographic findings of normal structures and pathologic lesions of the hip joint are introduced and explained briefly.

In abdominal Ultrasonography, the fatty liver is diagnosed through hepatic parenchymal echo increased parenchymal density and unclear blood vessel boundary, and according to many studies, abdominal Ultrasonography has 60~90% of sensitivity and 84~95% of specificity in diagnosis of fatty liver, but the result of Ultrasonography is dependent on operators, so there can be difference among operators, and quantitative measurement of fatty infiltration is impossible. Among examinees who same day received abdominal Ultrasonography and chest computed tomography (CT), patients who were diagnosed with a fatty liver in the Ultrasonography were measured with liver Hounsfield Units (HU) of chest CT imaging to analyze the accuracy of the fatty liver diagnosis. Among 720 subject examinees, those who were diagnosed with a fatty liver through abdominal Ultrasonography by family physicians were 448, which is 62.2%. The result of Liver HU measurement in the chest CT imaging of those who were diagnosed with a fatty liver showed that 175 out of 720 had the measured value of less than 40 HU, which is 24.3%, and 173 were included to the 175 among 448 who were diagnosed through Ultrasonography, so 98.9% corresponded. This indicates that the operators' subjective ability has a great impact on diagnosis of lesion in Ultrasonography diagnosis of a fatty liver, and that in check up chest CT, under 40 HU in the measurement of Liver HU can be used for reference materials in diagnosis of a fatty liver.

Objectives : The aim of this study was to evaluate the usefulness of ultrasonography of knee osteoarthritis. Methods : 124 osteoarthritis patients classified by the American College of Rheumatology (ACR) clinical criteria were included in the study. Simple X-ray and ultrasonography examination (effusion, osteophyte, articular cartilage, Backer's cyst) of knee in pain were performed. Also VAS, KWOMAC score were checked. Results : X-ray showed abnormal findings in 112 patients, but ultrasonography showed abnormal findings in all 124 patients. 12 Patients with unremarkable knee X-ray showed effusion and osteophyte in the ultrasonography. Effusion was discovered only in 18 cases of X-ray and 62 cases of ultrasonography. Group with effusion showed higher VAS mean figure but couldn't retrieve significant difference. KWOMAC showed no significant difference. Conclusions : Osteoarthritis patients with no abnormality in X-ray diagnosed abnormal findings through sonograph, which manifest that sonograph can be utilized for differential diagnosis especially sensitive on the problem of effusion.

Purpose: The aim of this study was to establish a simple formula to predict renal length in children using a Technesium-99m dimercaptosuccinic acid (DMSA) scan data, and to compare it with the formula derived from ultrasonography, which is widely accepted. Methods: Children who underwent a DMSA scan and ultrasonography were reviewed retrospectively, and those who had anatomical urinary tract abnormalities or urinary tract infections were excluded. Results: A total of 230 children (84 males and 146 females; age, 1 month to 16 years; mean age, $16.8{\pm}27.4$ months). Mean renal length measured by DMSA scan was longer than that by ultrasonography ($6.38{\pm}1.16$ vs. $6.02{\pm}1.14cm$; P < 0.001). Renal length was correlated with age, weight, height, and body surface area on the DMSA scan and ultrasonography, and showed the strongest positive correlation with height. The following formulae were established to predict renal length: mean renal length (cm) = 5.433 ${\times}$ height (m) + 2.330 (R2, 0.833) using the DMSA scan data, and mean renal length (cm) = 5.367 ${\times}$ height (m) + 2.027 (R2, 0.853) using ultrasonography data. Conclusion: We propose a simple height-based formula to predict renal length in children using a DMSA scan data, and validate it by comparing with ultrasonography formula.

Purpose: The authors have experienced various lesions that simulate ganglion of the foot on the ultrasonography. The purpose of this study is to evaluate ultrasonographic findings of soft tissue lesions, which were interpreted as ganglion but confirmed as different lesions in the foot. Materials and Methods: We reviewed a database of patients with ganglion on the ultrasonography from two different institutions. There were 109 patients who underwent both ultrasonography and surgical confirmation. Twenty one lesions were identified, of which initial interpretation on the ultrasonography included ganglion which pathology revealed to be different lesions. All images were evaluated by one musculoskeletal radiologist, regarding size, margins, internal echogenicity of lesions, and presence of posterior enhancement. Results: Of 21 lesions, there were 6 fibrous tumors including fibroma, giant cell tumor of tendon sheath, and fibromatosis, 3 hemangiomas, 2 epidermal inclusion cysts, 2 chondromas, 2 angioleiomyomas, 1 trichilemal cyst, 1 neurofibroma, 1 granular cell tumor, 1 neurilemmoma, 1 neuromyxoma, and 1 nodular hidradenoma. Mean size of the lesion was 1.1 cm. Margins were smooth in 10, mild lobulation in 8 and marked lobulation in 3 lesions. Lesions were hypoechoic in 16, anechoic in 4 and isoechoic in 1 case. Posterior acoustic enhancement was definitely present in 5 lesions. Conclusion: On the ultrasonography, various soft tissue lesions of the foot may be confused with ganglion. During surgical resection care should be given even to a simple ganglion as it might turn up to be a solid lesions such as fibrous tumors.
