Objective : This study attempted to evaluate the ultrasonographic diagnosis of sinusitis compared to X-ray diagnosis and further to help the diagnosis and treatment of sinusitis through oriental medicine. Methods : Both A-mode ultrasonography and X-ray were taken of 30 symptom-positive patients and 10 symptom-negative controls. Nasal obstruction, rhinorrhea, postnasal drip, headache (facial pain), hyposmia (anosmia), throat discomfort and chronic cough were included in the symptoms of sinusitis. Both ultrasonographic and X-ray findings were divided into four groups (clear, mucosal thickening, air-fluid level and cystic shape) according to severity. Results : 1. The symptoms of patients (n=30) were as follows: nasal obstruction (83.3%), rhinorrhea (70.0%), postnasal drip (60.0%), chronic cough (53.3%), headache (40.0%), throat discomfort (40.0%), hyposmia (26.7%). 2. There was a significant correlation between symptoms and ultrasonographic findings (n=40, ${\gamma}=0.550$, P=0.001). 3. There was a significant correlation between symptoms and X-ray findings (n=40, ${\gamma}=0.555$, P=0.001). 4. There was a significant whole coincidence between ultrasonographic and X-ray findings (n=60, ${\gamma}=0.335, P=0.00l). Moreover, there was a significant coincidental trend between the two findings as they became severe (n=60, ${\gamma}=6.284$, P=0.012). 5. The distance of the ultrasonographic echoes was as follows: clear echo (n=9, from transducer pulse to air mucosa echo) $0.90{\pm}0.19cm$, mucosal thickening echo (n=23, from transducer pulse to air mucosa echo) 1.85{\pm}0.14cm, air-fluid level echo (n=26, from transducer pulse to back wall echo) $3.70{\pm}0.16cm$. 6. The highest diagnostic reliability of the ultrasonographic findings compared to X-ray findings was as follows: over-diagnosis in clear finding 77.3%, matched diagnosis in mucosal thickening finding 62.0%, matched diagnosis in air-fluid level finding 86.7%, matched diagnosis and under-diagnosis in cystic shape finding 50.0%. 7. In mucosal thickening, air-fluid level and cystic shape finding, there was a significant individual coincidence between the ultrasonographic and X-ray findings. In clear finding, there was no significant individual coincidence between the two findings. Conclusion : The ultrasonographic diagnosis significantly reflects the symptoms of sinusitis like X-ray diagnosis and is a valuable tool to screen prognostic factors such as mucosal thickening, air-fluid level and cyst. Therefore the ultrasonography will be useful for the diagnosis and treatment of sinusitis in oriental medicine.

In this study, ultrasonographic evaluations were made after experimentally induced ascites in dogs. Ultrasonographic evaluation allowed to identify the earliest fluid accumulation between the spleen and the left kidney after the administration of 0.9% normal saline at 8 ml/kg into the abdominal cavity in dogs. Ultrasonographic finding were observed in order between the spleen and the left kidney, the liver, the pelvic cavity. It is considered that the most adequate pare f3r the early detection of ascites is between the spleen and the left kidney, and the least amount of detection fluid is 8 ml/kg in dogs.

To evaluate of the ultrasonographic changes in hemiplegic and unaffected knee joints of hemiplegic ambulators with recent onset stroke. Twenty patients (40 knees) with prevalence duration of 14-39 weeks (mean 24.70 weeks) after a stroke insult were included. All participants were walking independently without leg dragging, had no previous knee injury. There were significant differences in intercondylar cartilage thickness and pes anserinous tendinopathy (PAT) between hemiplegic and unaffected knees (p<0.05). There were no differences in cartilage thickness of medial condyle and lateral condyle, patellar tendinitis/bursitis, suprapatellar effusion, synovitis, joint space narrowing, and Baker's cyst of ultrasonographic findings and x-ray findings in hemiplegic knee compared to the control except PAT (p<0.05). In hemiplegic knee, medial or lateral condylar cartilage thickness was significantly correlated with body weight, intercondylar cartilage thickness, and PAT (p<0.05). PAT was significantly correlated with Brunnnstrom stage and condylar cartilage thickness (p<0.05). Knee pain was significantly correlated with lateral condylar cartilage thickness (p<0.1). The hemiplegic knee had more ultrasonographic abnormalities including PAT and more cartilage thickness preservation in patient with recent onset stroke. Intraarticular sonographic findings including cartilage thickness was significantly correlated with extraarticular findings including PAT and a symptom of knee pain.

Rupture of the rectus femoris at the musculotendinous junction is very rarely reported in the literature, especially which is caused by chronic repetitive stimulation. A 21 year old soldier complained of progressing right thigh pain and mass for 8 weeks after military training. MRI of the right thigh showed inhomogenous mass lesion suspecting soft tissue tumor. However ultrasonographic examination showed torn retracted rectus femoris tendon at musculotendinous junction. One year after primary repair of ruptured tendon, the patient is free from symptoms and returned to full previous activities. Knowledge of this sonographic and MRI finding will help the surgeon to diagnose and treat this rare injury.

This study was undertaken to determine the normal serial ultrasonographic appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored by ultrasonography in 10 Shih-tzu bitches. Serial ultrasonographic examination was done daily during the first week, 3 days interval from 8 to 30 days, and weekly from 31 to 100 days postpartum. All 10 postpartum bitches had normal involution by gross finding, vaginal discharges, and by ultrasonographic findings, uterine shape and echogenicity. The uterine diameter in the placental sites was decreased from $23.56{\pm}1.45$ mm at 1 day to $14.08{\pm}1.55$ mm at 7 day, and in the interplacental sites was decreased from $14.64{\pm}1.28$mm at 1day to $9.61{\pm}1.46$mm at 7 day postpartum. At 65 days postpartum the uterine diameter was 5-6 mm both placental and interplacental sites, and the uterine horns were uniform hypoechic, tubular structures without enlargement. Therefore, complete involution of the uterus occured 65 days. It was concluded that normal postpartum uterine involution in Shih-tzu bitches appeared to be completed 65 days postpartum by gross findings such as vaginal discharges, and ultrasonographic findings. And ultrasonographic characteristics of the postpartum uterine involution were described. Therefore, these result suggest that ultrasonographic assessment is a reliable method for diagnosing the subinvolution of placental sites and uterine dysfunction, such as pyometra in the bitch.

Diagnosis of acute appendicitis in children is sometimes difficult. The aim of this study is to validate a clinical scoring system and ultrasonography for the early diagnosis and treatment of appendicitis in childhood. This is a prospective study on 59 children admitted with abdominal pain at St. Mary's Hospital, the Catholic University of Korea from July 2002 to August 2003. We applied Madan Samuel's Pediatric Appendicitis Score (PAS) based on preoperative history, physical examination, laboratory finding and ultrasonography. This study was designed as follows: patients with score 5 or less were observed regardless of the positive ultrasonographic finding, patients with score 6 and 7 were decided according to the ultrasonogram and patients above score 8 were operated in spite of negative ultrasonographic finding. The patients were divided into two groups, appendicitis (group A) and non-appendicitis groups (group B). Group A consisted of 36 cases and Group B, 23 cases. Mean score of group A was 8.75 and group B was 6.13 (p<0.001). Comparing the diagnostic methods in acute appendicitis by surveying sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, PAS gave 1.0000, 0.3043, 0.6923, 1.0000, and 0.7288, and ultrasonography gave 0.7778, 0.9130, 0.9333, 0.7241, and 0.8300 while the combined test gave 1.0000, 0.8696, 0.9231, 1.0000, and 0.9490, respectively. Negative laparotomy rate was 3 %. In conclusion, the combination of PAS and ultrasonography is a more accurate diagnostic tool than either PAS or ultrasonography.

Hepatic mass was aspirated under the guidance with ultrasound in 9-year old female maltese with signs of anorexia, hematochezia, vomiting, depression, and abdominal distension. Radiographic and abdominal ultrasonographic examinations were performed, which revealed enlarged tubular shaped uterine mass and solitary, small round hyperechoic hepatic mass dorsal to gall bladder as an incidental finding. Ultrasound-guided fine needle aspiration was completed, but histologic confirmation should be made for definitive diagnosis by tissue core or wedge biopsy.

In a 10-year old mixed dog, a $10{\times}10{\times}4$ cm mass was palpated around the left caudal thoracic mammary gland with abdomen expension. In hormonal assay, serum concentrate of progesterone was 0 pg/ml and serum concentrate of estradiol was 66.7 pg/ml. Radiological finding of the mammary gland showed higher density than that of soft tissue and ultrasonographic finding showed inhomogeneous in echogenicity. Light microscopic view of mammary gland showed neoplastic hyperplasia of epithelial and myoepithelial cells and showed some metaplastic lesion of these cells to cartilage or bone tissues with metastasis to the lung. This case was diagnosed as malignant mixed mammary tumor.

12-month-old Buldig and 3-year-old German Shepherd, treated with corticosteroids duringthe late pregnancy, were referred to the Veterinary Teaching Hospital, Chonnam National University, with chief complaints of vaginal discharge. Radiographic, ultrasonographic and surgical findings that obtained from each cases were as follows; case I: Radiographic findings were identified 2 fetuses that were normal skeleton, however, fetal viability could not be determined. Ultrasonographic findings were identified absence of fetal heartbeat and fetal movement, abnormal echogenicity of the abdominal visera, and echogenic materials remaining within the fetal fluid. After hysterotomy, macroscopic findings of uterus were liquefied materials remaining within the uterine lumen. Fetuses were excessively autolysis (falling off the hair, depression of the eye, and necrosis of the abdormal visera and skin). case II: Radiographic findings were identified irregular fetal structures and fetal movement, loss of recognizable fetal anatomy, dislocation of fetal veterbrae and echogenic materials remaining within the uterine lumen. After ovariohysterectomy, macroscopic finding of uterus and fetus were thickened uterine wall, yellowish-brown colored administration of corticosteroids during gestation should be contraindicated because fetal death is inducced. Ultrasonography has an advantage over radiography in that it permits evaluation of fetal viability.
