  • Purpose : This study is to offer clinical primary data that examines the change of imaging structure and the quantitative evaluation of muscle activity on myofascial trigger points. This study examines neuromuscular physiological characteristic by comparing the differences in physical findings, pressure pain threshold, imaging, and electrophysiological characteristics in latent and active myofascial trigger points muscle and normal muscle through the following experimental procedures. Methods : The participants for the study were thirty-three adults in their twenties. We divided three groups into normal, latent and active myofascial trigger points groups by physical findings. We analyzed the results of measured pressure pain, threshold for pain, ultrasound imaging perform for structure characteristic of muscle, surface EMG according to type of muscle contraction for function of muscle contraction. Results : Significant differences were indicated in pressure pain threshold (p<0.05). Significant differences were discovered in the ultrasound imaging analysis. There were increases in muscle Echogenicity white area index (p<0.001). There were significant differences that decrease in %MVIC (p<0.05), increase in MDF (p<0.05). Conclusion : From these results, active rnyotascial trigger points muscle showed quality deterioration on ultrasound imaging and decreased function of muscle contraction, increased motor unit action potential of II type fiber, and electrophysiologically. Imaging structure and neuromuscular physiological characteristic can be diagnostic and quantitative analytical techniques for myofascial pain syndrome and a primary factor that reflected in physical therapy intervention.

  • Pancreatic metastasis from malignant phyllodes tumor (PT) of the breast is rare, and only a few cases have been reported in the literature. Here, we report a case of pancreatic metastasis from malignant PT of the breast in a 48-year-old woman. She had had three episodes of recurrence of malignant PT in her right breast. She presented with epigastric pain for 2 months. Computed tomography and magnetic resonance imaging revealed a 6 cm-sized, well-defined, heterogeneous mass with peripheral enhancement in the body of the pancreas. Endoscopic ultrasonography-guided fine-needle aspiration was performed, and the pathologic report suggested spindle cell mesenchymal neoplasm. Subsequently, surgical excision was performed, and the mass was confirmed as a metastatic malignant PT. The imaging findings are discussed and the literature is briefly reviewed in this report.

  • Ultrasound imaging in clinical practice is one of the widely used diagnostic methods because there is no radiation risk, more cost- effective compared to MRI or CT, and possible to perform an intervention through fast real-time imaging. In order to increase the diagnostic value, the studies of contrast-enhanced ultrasound (CEUS) using an ultrasound contrast agent have been actively conducted since about 50 years ago and are being used clinically in vascularity and microcirculation of internal organs. Although ultrasound is actively used for the diagnosis and treatment of various diseases in musculoskeletal disorders, there are some limitations in diagnosing mild or small lesions, inflammatory reactions, or abnormalities at the molecular level. In this review, the principles, types, and research, and clinical applications of ultrasound contrast agents have been summarized and introduced. If we understand the characteristics of the ultrasound contrast agents and anatomical knowledge, as well as molecular changes, the ultrasound contrast agents are widely applied in musculoskeletal disorders and have tremendous potential for diagnosis and treatment.

  • Here, we report a case of ultrasound-assisted subarachnoid block in a patient with severe kyphosis. A 69-year-old man was scheduled for metal removal from hip screws. He had a previous experience with subarachnoid block using the landmark-guided technique, but it was very difficult due to severe kyphosis. However, we could easily determine the correct needle insertion point using ultrasound imaging and performed a successful dural puncture on the first attempt. This case demonstrates the clinical usefulness of ultrasound imaging for subarachnoid blocks in patients with severe kyphosis.

  • A large abdominal mass was incidentally found in a 13-year-old mixed-breed dog and was confirmed to be a cecal gastrointestinal stromal tumor (GIST). Contrast-enhanced ultrasound and post-contrast computed tomography (CT) showed mild contrast enhancement of the mass, indicating low blood flow. The tumor origin was determined to be the cecum by identifying the vessels supplying the mass on post-contrast CT. The exophytic growth of the tumor left the cecal lumen intact without obstruction. This report described the CEUS and CT perfusion of the cecal GIST and perfusion evaluation can help diagnose and characterize GISTs in dogs.

  • In children and adolescents, inguinal and scrotal diseases are relatively common, and imaging is very useful for the diagnosis and differential diagnosis of these diseases. Therefore, it is important to understand the imaging findings of these diseases. In this article, we classify these diseases into small testes, cryptorchidism, patent processus vaginalis, acute scrotum pain, trauma, testicular tumors, and others and describe their characteristic findings.

  • Ultrasonography is one of the fields on the imaging studies within intra-abdominal organs. A blood test is a typical method of clinical chemical examination on the in vivo test of clinical symptoms. Fatty liver is performed simultaneously two kinds of diagnostics methods, intra-abdominal ultrasound and blood tests. At an implementing this, the standard of blood tests value was the TBIL, TC, AST, ALT, ALP, GGT, TG, HDL-C, GLU. In this study analyzing the accuracy of the two kinds of test, ultrasonography and blood test, on patients with fatty liver. From January to March 2012, patients 459 determined fatty liver within 1350, who received health examination simultaneously on the intra-abdominal ultrasonography and blood tests. Same result of ultrasonography and blood test's patients were 459 ie, 60.8%. and different result of those examinations was 280 ie, 39.2%. Consequently diagnostic accuracy was 60.8%. It presumably caused by differences in the diagnostic performance of ultrasound professionals(Radiologist or Radiological Technologist). In order to overcome this, ongoing educational and study will be needed.

  • Background: It is necessary to find and develop the effective way of intervention for patients with neck pain, since the neck pain is becoming increasingly common throughout the world. To identify the altered motor control in patient with neck pain would be informative to find and develop the effective way of intervention. Objects: The aim of this study was to review literature regarding the altered motor control in patients with neck pain, measured by using surface electromyography (sEMG), ultrasonography, and functional magnetic resonance imaging (fMRI), and to suggest prospective research work on neck pain. Methods: Case-control (neck pain/healthy) studies published between 2004 and 2015 that investigated neck muscle activation, thickness, cross-sectional area, and fat infiltrate were searched in Scopus, PubMed, and ScienceDirect. Twenty-eight articles were included in this study. Results: sEMG, ultrasonography, and fMRI were used complementarily to investigate the altered superficial and deep neck muscle activation, thickness, cross-sectional area, and fat infiltrate in patients with neck pain. They showed the following altered motor control when compared retrospectively with healthy subjects or during specific functional tasks: (1) increased superficial muscle activation, (2) lesser deep muscle thickness, (3) smaller cross-sectional area of the deep muscle, and (4) greater fat infiltrate in deep muscles. In particular, among the women, the office workers showed higher muscle activation of superficial neck muscles during functional tasks, although they did not have neck pain, than those who were not office workers. Conclusion: Studies revealed that patients with neck pain showed an altered motor control when compared with healthy subjects by using various assessment modalities. Understanding this phenomenon would help researchers design an effective intervention for alleviating neck pain or to evaluate the effectiveness of the intervention. In addition, we recommend that female office workers take measures to care for their necks before developing neck pain.

  • Objective: To verify the basic preoperative evaluation in the discrimination between benign and malignant adnexal masses in our clinical practice. Materials and Methods: Data were collected on the records of 636 women with adnexal masses who had undergone surgery either by open or endoscopic approaches. Those with obvious signs of malignancy, any history of cancer, emergency surgeries without basic evaluation were excluded. The preoperative features by age, ultrasound and serum Ca125 level were compared with final histopathological diagnosis at the four departments of the institution. These are the general gynecology (Group 1: exploratory laparotomy), the gynecologic endoscopy (Group 2: laparoscopy and adnexectomy), the gynecological oncology (Group 3: staging laparotomy) and the gynecologic endocrinology and infertility (Group 4: laparoscopy and cystectomy). Results: There were simple and complex cyst rates of 22.3% and 77.2%, respectively. There were 86.3% benign, 4.1% (n:20) borderline ovarian tumor (BOT) and 6.4% (n:48) malignant lesions. There were 3 BOT and 9 ovarian cancers in Group 1 and one BOT and two ovarian cancer in the Group 2. During the surgery, 15 BOT (75%) and 37 ovarian cancer (77%) were detected in the Group 3, only one BOT was encountered in the Group 4. The risk of rate of unsuspected borderline or focally invasive ovarian cancer significantly increased by age, size, complex morphology and Ca125 (95% CI, OR=2.72, OR=6.60, OR=6.66 and OR=4.69, respectively). Conclusions: Basic preoperative evaluation by comprehensive ultrasound imaging combined with age and Ca125 level has proved highly accurate for prediction of unexpected malignancies. Neither novel markers nor new imaging techniques provide better information that allow clinicians to assess the feasibility of the planned surgery; consequently, the risk of inadvertent cyst rupture during laparoscopy may be significantly decreased in selected cases.
