Today, despite many optimal imaging methods for evaluation of ovarian mass, the survival rate of patient was not significantly changed. Object of present study was evaluation of Clinico Ultra- Sonography and pathological findings of ovarian masses in patients referred to Kosar Hospital. In this analytic study, information of clinico Ultra-Sonography and pathological findings was obtained from the 874 women with ovarian mass reffered to the hospital in Kasar Hospital from 2007 to 2017 by checklist. Both descriptive and analytical statistical methods were used (P < 0.05). In this study, of the total ovarian masses, 4.5% or 39 were malignant, 70.6%, or 617 benign, 5.9%, or 52 borderline. The relationship between clinical findings and radiological findings is statistically significant. The relationship between clinical presentation and pathologic categorization of ovarian masses was significant.. The association between radiological findings and type of ovarian mass in terms of origin was statistically significant (P < 0.05). The prediction of malignant potential of ovarian masses, while providing necessary measures and the extent of surgery, prevents unnecessary offensive action. Considering recent advances in imaging techniques, especially ultrasound, and its proper precision in distinguishing benign tumors from malignant, using this method to predict the type of pathology is necessary.

This study aimed to evaluate the diagnostic value of ultrasonographic median nerve cross-sectional area and median nerve-tunnel indices comparing to nerve conduction study (NCS) test in patients with carpal tunnel syndrome (CTS). eventy-one hand with clinical symptoms of CTS and fifty-five healthy hands were participated in the study. The cross sectional areas of the median nerve and carpal tunnel in proximal and distal of carpal tunnel were obtained by ultra sonography. The proximal and distal nerve/tunnel indices were obtained by calculating the ratio between the proximal and distal cross-sectional areas of the median nerve to those of the carpal tunnel. The mean of nerve-tunnel index in the distal and proximal were significantly different between patients with CTS and normal (p>0.001). The study showed no difference between the proximal and distal nerve/tunnel index and also between nerve-tunnel Index and median nerve cross-sectional area. Designated cut-off points of proximal nerve-tunnel index for mild, moderate and severe CTS was determined at 6.34, 6.36 and 6.76 with a diagnostic sensitivity of 47.4, 75.8 and 85.7%, respectively, while the cut-off point of distal nerve-tunnel Index was 6.58, 6.58 and 7.61with a diagnostic sensitivity of 47.4, 67.6 and 78.6%, respectively. The results showed that the nerve/tunnel index is not a reasonable replace for NCS technique, due to its low sensitivity and specificity, especially in mild cases. Also, our study showed no significant difference between using ultra sonography nerve-tunnel index and median nerve cross-sectional area in the diagnosis of CTS.

Infection and Peri-renal abcess have always been a diagnostic problem for radiologists.
They cause high morbidity and mortality in late diagnosis.
Ultrasonography (US) and CT-scan enable the radiologist to search the retroperitoneal space clearly and make a smart diagnosis by US and then drained with US guide are introduced.
Low cost, high speed of drainage and complete response to therapy are the advantages which can introduce ultrasonography as a good alternative to open surgery.
