  • 슬관절 내측 통증은 정형외과 영역에서 흔한 문제이다. 초음파를 통하여 내측측부인대 점액낭염, 내측 반월상 연골 낭종, 내측측부인대 퇴행성 변화, 내측 반월상 연골의 탈출 등을 확인할 수 있다. 증식치료는 무릎의 내측 통증을 주소로 내원한 환자에서 효과적인 치료법이다. 내측측부인대 점액낭염 환자에게 증식치료 시행 후 근골격계 초음파로 추시하여 점액낭염의 호전을 관찰한 증례를 보고하고자 한다.

  • Ulnar nerve compression in the cubital tunnel is a common entrapment syndrome of the upper limb. Pulsed radiofrequency lesioning (PRFL) has been reported as a treatment method for relieving neuropathic pain. Since the placement of the electrode in close proximity to a targeted nerve is very important for the success of PRFL, ultrasound seems to be well suited for this technique. A 36-year-old woman presented with complaints of numbness and pain on the medial aspect of the elbow and the pain radiated down to the $4^{th}$ and $5^{th}$ fingers for 10 years after she suffered an elbow contusion, we then scheduled this woman for the ultrasound guided PRFL of the ulanr nerve. The initial ultrasound examination demonstrated a swollen nerve, loss of the fascicular pattern and an increased cross sectional area of the ulnar nerve. After confirmation of the most swollen site of the nerve via ultrasound, two sessions of PRFL were performed. The postprocedural 10 cm visual analog scale score decreased from 8 to 1 after the two sessions of PRFL.

  • Background: Physiatrists are facing with survivors from disasters in both the acute and chronic phases of muscle and nerve injuries. Similar to many other clinical conditions, neuromusculoskeletal ultrasound can play a key role in the management of such cases (with various muscle/nerve injuries) as well. Accordingly, in this article, a recent single-center experience after the Turkey-Syria earthquake will be rendered. Methods: Ultrasound examinations were performed for various nerve/muscle lesions in 52 earthquake victims referred from different cities. Demographic features, type of injuries, and applied treatment procedures as well as detailed ultrasonographic findings are illustrated. Results: Of the 52 patients, 19 had incomplete peripheral nerve lesions of the brachial plexus (n=4), lumbosacral plexus (n=1), and upper and lower limbs (n=14). Conclusion: The ultrasonographic approach during disaster relief is paramount as regards subacute and chronic phases of rehabilitation. Considering technological advances (e.g., portable machines), the use of on-site ultrasound examination in the (very) early phases of disaster response also needs to be on the agenda of medical personnel.

  • Axillary lymph node schistosomiasis is a form of ectopic schistosomiasis, in which the Schistosoma adult worms or eggs are infected in the axillary lymph nodes. A 53-year-old woman visited our hospital with a small mass in the right armpit, which had been present for over 1 month. Histological examination of biopsy samples from the right axillary lymph nodes revealed granulomas containing calcified Schistosoma eggs. This is the first authentic case of ectopic schistosomiasis identified in the axillary lymph nodes.

  • Ultrasound examination using ultrasound equipment is an ultrasound device that images human organs using sound waves and is used in various areas such as diagnosis, follow-up, and treatment of diseases. However, if the quality of ultrasound equipment is not guaranteed, the possibility of misdiagnosis increases, and the diagnosis rate decreases. Accordingly, The Korean Society of Radiology and Korea society of Ultrasound in Medicine presented guidelines for quality management of ultrasound equipment using ATS-539 phantom. The DenseNet201 classification algorithm shows 99.25% accuracy and 5.17% loss in the Dead Zone, 97.52% loss in Axial/Lateral Resolution, 96.98% accuracy and 20.64% loss in Sensitivity, 93.44% accuracy and 22.07% loss in the Gray scale and Dynamic Range. As a result, it is the best and is judged to be an algorithm that can be used for quantitative evaluation. Through this study, it can be seen that if quantitative evaluation using artificial intelligence is conducted in the qualitative evaluation item of ultrasonic equipment, the reliability of ultrasonic equipment can be increased with high accuracy.

  • Automated breast ultrasound (ABUS) equipment is a new innovative technique for 3D automatic breast scanning, but limited for the examination in the concave axillary region. The purpose of this study was to determine feasible candidate materials for the ultrasonic wave propagation media in ABUS, enabling the evaluation of the axillary region. Ultrasonography was performed using an ABUS system ($Invenia^{TM}ABUS$, GE, USA) on the ultrasound-specific phantom (UC-551M-0.5, ATS Laboratories, USA) covered by different candidate materials. The validity of feasible candidate materials was evaluated by image quality. Three independent radiological technologists, with more than 10 years of experience, visually assessed on the images. The inter-observer agreements according to the candidate materials were tested using Cronbach's alpha. Unenveloped solidified carrageenan can be a feasible material for the use of ABUS with excellent test reliability. Therefore, the coverage of the axillary region with carrageenan may be effective for ABUS which was originally developed for the convex anatomic structure as female breast.

  • Purpose: Closed reduction is most common treatment method for nasal bone fracture but it requires secondary correction operation commonly. For preventing secondary revision, we applied ultrasonography during closed reduction of nasal bone fracture and examined the result of operation. Methods: 80 patients were sorted into 2 groups, ultrasound-guided closed reduction group(n=40) and manual closed reduction group(n=40). We classified the unilateral fracture involving lower 1/2 of nasal bone into type I, the bilateral fracture involving lower 1/2 of nasal bone into type III and the fracture of upper 1/2 of nasal bone into type III. The occurrence rate of overcorrection and undercorrection were evaluated by comparing preoperative and postoperative MDCT(Multi Direction Computed Tomography). Results: In manual closed reduction group, overcorrection were found in 4 patients and undercorrection were found in 3 patients. In ultrasound-guided closed reduction group, overcorrection was not observed and undercorrection was observed in 2 patients. Conclusion: Intraoperative ultrasound evaluation of nasal bone fracture resulted in reduced occurrence rate of secondary nasal deformities, showed easier detection of the fractured site and have superiority upon simple physical examination or simple x-ray.

  • Primary hyperparathyroidism (PHP) is rare in dogs. Mainly functional solitary parathyroid adenoma causes hypercalcemia due to excessive autonomous secretion of parathyroid hormone (PTH). PHP can be diagnosed based on serum calcium phosphorus, ionized calcium and PTH, and cervical ultrasound provides important information about the number size and location of parathyroidal lesion. Ultrasound guided intralesional ethanol injection has been used as an alternative to surgical treatment of PHP. In this case, PHP was diagnosed in 12 year-old Pug with clinicopathologic examination and cervical ultrasound, and the parathyroidal mass was ablated successfully through ultrasound guided ethanol injection.

  • Purpose: To determine the utility of digital rectal examination (DRE), serum total prostate specific antigen (tPSA) estimation, and transrectal ultrasound (TRUS) for the detection of prostate cancer (PCa) in men with lower urinary tract symptoms (LUTS). Materials and Methods: All patients with abnormal DRE, TRUS, or serum tPSA >4ng/ml, in any combination, underwent TRUS-guided needle biopsy. Eight cores of prostatic tissue were obtained from different areas of the peripheral prostate and examined histopathologically for the nature of the pathology. Results: PCa was detected in 151 (50.3%) patients, remaining 149 (49.7%) showed benign changes with or without active prostatitis. PCa was detected in 13 (56.5%), 9 (19.1%), 26 (28.3%), and 103 (74.6%) of patients with tPSA <4 ng/ml, 4-10 ng/ml, 10-20 ng/ml and >20 ng/ml respectively. Only 13 patients with PCa had abnormal DRE and TRUS with serum PSA <4 ng/ml. The detection rate was highest in patients with tPSA >20 ng/ml. The association between tPSA level and cancer detection was statistically significant (p<0.01). Among 209 patients with abnormal DRE and raised serum PSA, PCa was detected in 128 (61.2%). Conclusions: The incidence of PCa increases with increasing serum level of tPSA. The overall screening and detection rate can be further improved by using DRE, TRUS and TRUS-guided prostate needle biopsies.
