| 1 | Routine magnetic resonance cholangiography compared to intra-operative cholangiography in patients with suspected common bile duct stones显示文摘BACKGROUND:Magnetic resonance cholangiography (MRC)is a non-invasive method for imaging biliary ducts.When used to exclude common bile duct(CBD) stones,MRC may obviate the need for intra-operative cholangiography(IOC).In this prospective study,MRC and IOC were compared for the diagnosis of suspected stones of the CBD. METHODS:Thirty patients with gallstones and suspected CBD lithiasis(abnormal serum liver tests and CBD>7 mm on ultrasound)had MRC followed by open cholecystectomy and IOC.MR imaging was done using a 1.5-T whole body scanner(Signa,General Electric Medical Systems).A torso phased-array coil with a 4-channel receiver was used for data acquisition. RESULTS:Over a period of 18 months,30 patients(average age 53.9±13.3 years;range 38-76 years)were enrolled in this study.Eleven patients were male(36.7%)and 19 female(63.3%).MRC revealed CBD stones in 19 patients, while IOC revealed CBD stones in 22.The sensitivity of MRC in detecting CBD stones was 81.8%,and the specificity was 87.5%.The positive predictive value was 94.7%,and the negative predictive value was 63.3%. CONCLUSIONS:Pre-operative MRC may obviate the need for IOC.MRC reduces operative time,is less invasive, and may also alleviate damage to the CBD that can occurduring IOC.MRC can identify CBD stones pre-operatively and can help surgeons plan safe procedures.Pre-operative MRC should be done routinely in patients whose clinical or biochemical findings suggest the possibility of CBD stones. | Fariborz Eshghi Roohollah Abdi | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，5： | 4 |

| 3 | PRODUCTION PLANNING PROBLEM WITH PRICING UNDER RANDOM YIELD:CVAR CRITERION显示文摘In this paper,we address a basic production planning problem with price dependent demand and stochastic yield of production.We use price and target quantity as decision variables to lower the risk of low yield.The value of risk control becomes more important especially for products with short life cycle.This is because,the profit implications of low yield might be unbearable in the short run.We apply Conditional Value at Risk(CVaR) to model the.risk.CVaR measure is a coherent risk measure and thereby having nice conceptual and mathematical underpinnings.It is also widely used in practice.We consider the problem under general demand function and general distribution function of yield and find sufficient conditions under which the problem has a unique local maximum.We also both analytically and numerically analyze the impact of parameter change on the optimal solution.Among our results,we analytically show that with increasing risk aversion,the optimal price increases.This relation is opposite to that of in Newsvendor problem where the uncertainty lies in demand side. | Saman Eskandarzadeh Kourosh Eshghi Mohammad Modarres Yazdi Mohsen Bahramgiri | 2014 | Journal of Systems Science and Systems Engineering2014，23，3： | 3 |
