Comparing the Diagnostic Precision of Clinical Examination and MRI with Findings from Arthroscopy in Traumatic Knee Injuries with Femur or Tibia Shaft Fracture

Background: Diagnosis of knee injuries following trauma to the lower extremity is very important and needs to be carefully examined. This study aimed at comparing the diagnostic precision of clinical examination (CE) and MRI with findings from arthroscopy in traumatic knee injuries with femur or tibia shaft fracture.Methods: A cross-sectional study was conducted on 164 patients with traumatic knee injuries with femur or tibia shaft fracture who had been referred to Imam Hossein Hospital, Shahroud, between March 2014 and February 2015. We compared CE and MRI with arthroscopic findings (gold standard) to determine the concordance, accuracy, sensitivity, and specificity of injuries to the meniscus and knee ligaments.Results: The results showed that internal mucus rupture was the most common trauma, noted in 83 cases (50.6%), followed by anterior corrosion rupture, noted in 65 cases (39.6%). CE sensitivity was 68.4% and specificity was 96.2% for medial meniscal (MM) injuries, while sensitivity was 53.6% and specificity was 96.4% for lateral meniscal (LM) injuries. For anterior cruciate ligament (ACL) injuries, CE showed sensitivity of 77.2% and specificity of 91.8%. For posterior cruciate ligament (PCL) injuries, CE showed sensitivity of 52.6% and specificity of 98.6%. For MM injuries, MRI showed sensitivity of 92.5% and specificity of 86.5%, while for LM injuries, it showed sensitivity of 85.00% and specificity of 98.6%. For ACL injuries, MRI showed sensitivity of 86.7% and specificity of 93.8%, and for PCL injuries, MRI showed sensitivity of 84.5% and specificity of 98.8. For ACL injuries, the best concordance was with CE, while for MM and LM injuries, it was with MRI (P<0.001).Conclusions: Meniscal and ligament injuries in traumatic knee injury can be diagnosed through careful clinical examination, while requests for MRI can be reserved for complex or doubtful cases. CE and MRI used together have high sensitivity for ACL, PCL, and MM lesions, while for LM lesions, the specificity is higher

A Fundamental Micro Scale Study of the Roles of Associated Gas Content and Different Classes of Hydrocarbons on the Dominant Oil Recovery Mechanism by CWI

Abstract Various studies demonstrated new gaseous phase formation and oil swelling and viscosity reduction are the oil recovery mechanisms by carbonated water injection (CWI) with new gaseous phase formation being the major recovery mechanism for live oil systems. However, none of the previous studies investigated the influences of dissolved gas content of the oil and oil composition, on the new gaseous phase. This study attempts to provide insights on this area. Based on the results, during CWI as CO2 partitions into the oil the dissolved gas of the oil liberates, which leads to in-situ new gaseous phase formation. The dissolved gas content of the crude oil has a direct impact on the saturation and growth rate of the new gaseous phase. The new gaseous phase doesn’t form for oils that have an infinite capacity for dissolving CO2, such as light pure hydrocarbon components. Oils with limited capacity for dissolving CO2, such as heavy hydrocarbon components, are responsible for the formation of the new gaseous phase. Therefore for a live crude oil, the relatively heavier fractions of oil are responsible for triggering of the new gaseous phase and light to intermediate oil components control the further growth of the new gaseous phase
