  • Background: Facial nerve palsy presents a significant healthcare challenge, impacting daily life and social interactions. This systematic review investigates the potential utility of ultrasonography as a diagnostic tool for facial nerve palsy. Methods: Electronic searches will be conducted across various databases, including MEDLINE, EMBASE, CENTRAL (Cochrane Central register of Controlled Trials), CNKI (China National Knowledge Infrastructure), KMBASE (Korean Medical Database), ScienceON, and OASIS (Oriental Medicine Advanced Searching Integrated System), up to February 2024. The primary outcome will focus on ultrasonography-related parameters, such as facial nerve diameter and muscle thickness. Secondary outcomes will encompass clinical measurements, including facial nerve grading scales and electrodiagnostic studies. the risk of bias in individual study will be assessed using the Cochrane Risk of Bias assessment tool, while the grading of recommendations, assessment, development, and evaluations methodology will be utilized to evaluate the overall quality of evidence. Conclusion: This study aims to review existing evidence and evaluate the diagnostic and prognostic value of ultrasonography for peripheral facial nerve palsy.

  • 진단적 초음파가 태아에 미치는 영향에 대하여는 대부분의 연구결과, 심각한 영향을 미칠 가능성이 매우 낮다고 보고되고 있으나, 장시간의 과도한 조사는 초음파가 인체조직에 온도 상승이나 물리적인 영향을 줄 수 있어 초음파 검사시간에 따라 허벅지의 온도 변화를 조사하여 태아 초음파 검사 시 영향이 없는 시간을 알아보았다. 그 결과 초음파 검사 전보다 40분 안에는 온도가 떨어졌고 50분에는 허벅지의 온도가 검사 전보다 $1^{\circ}C$이상 올라가는 것을 확인하였다. 그러므로 40분 안에 초음파 검사를 한다면 안전한 것으로 추론해 본다.

  • 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.

  • 이 종설은 주관절에서의 초음파 검사 방법을 서술하였으며 주관절의 구조물들은 표층에 위치하기 때문에 초음파 사용이 용이하고 동적인 검사와 건 측과의 비교를 쉽게 할 수 있다는 장점으로 인하여 환자의 병변에 대한 많은 정보를 제공해 준다. 주관절에서 초음파 검사는 주관절 주변의 건, 근육, 인대 와 점액낭의 비정상적 형태뿐만 아니라 미세 골절(occult fracture), 주관(cubital tunnel) 내의 척골 신경의 압박 유무도 평가할 수 있다. 향후 주관절의 연부조직 이상을 진단하는 수단으로서의 초음파의 가치는 점점 증가할 것이다.

  • 고관절과 그 주위의 질환들의 진단적 검사는 그 동안 주로 단순 방사선 검사와 CT, MRI등이 이용되어 왔다. 그러나 고관절 주위의 건과 점액낭 등에 의한 병변에는 초음파 검사가 진단에 유용할 수 있으며 또한 추적 검사에도 활용될 수 있는 장점이 있다. 그 외에도 인공고관절 치환 수술 후에도 추적 검사상 활용도가 있어 그 사용이 넓어질 여지가 있다. 하지만 시술자의 숙련도에 따라 결과가 달라질 수 있다. 본 논문에서는 고관절 주위의 정상적인 구조물들의 초음파 영상과 병적 소견들을 소개하고 그 개략적인 것들을 설명하였다.

  • 상복부초음파검사에서 간실질의 에코 음영증가와 불명확한 혈관경계 등으로 지방간을 진단하는데, 여러 연구들에 의하면 지방간 진단에 84~95%의 특이도와 60~90%의 민감도를 가지나 결과가 검사자에 의존적이어서 차이가 있을 수 있고 지방의 침윤 상태의 정량적인 측정이 불가능하다. 건강검진의 상복부초음파검사와 흉부 전산화단층촬영(computed tomography; CT) 검사를 같은 날에 시행한 수검자중 초음파검사에서 지방간을 진단 받은 환자의 흉부 전산화단층촬영 영상에서 간(Liver) Hounsfield Units(HU)를 측정하여 지방간 진단의 정확성을 연관분석 하고자 하였다. 연구대상 수검자 720명 중 가정의학과 전문의에게 검사를 받고 지방간 판정을 받은 자는 448명으로 62.2%였다. 지방간 판정자의 CT영상에서 간 HU를 측정한 결과 40 HU 이하의 측정값은 720명 중 175명으로 24.3%이며, 초음파에서 진단 받은 448명에 175명 중 173명이 포함되어 98.9%가 일치하였다. 이는 지방간을 초음파로 진단 시 검사자의 주관적 경험과 능력이 병변을 진단하는데 크게 영향을 미친 것으로 생각되며 검진 CT검사에서 간 HU를 측정하여 40 HU 이하는 영상저장을 통하여 지방간 진단 시 참고자료로 활용될 수 있을 것으로 사료된다.

  • 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.
