1. In a high-risk population, low-dose CT screening detected lung cancer with 84.6% sensitivity and 98.6% specificity. 2. Screen-detected cancers were found at earlier stages as compared to interval cancers not picked up on screening. Evidence Rating: 1 (Excellent) Study Rundown: The US Preventative Services Task Force has recommended annual low-dose CT...
Image: PD 1. Low-dose computed tomography screening reduces lung cancer mortality when compared to screening with chest radiography 2. Screening for lung cancer with either modality resulted in very high false positive rates Original Date of Publication: August 4, 2011 Study Rundown: Prior studies have shown that lung cancer screening using chest radiography...
Image: PD 1. In evaluating abdominal stab wound patients, physical exam alone was sufficient to determine if patients required therapeutic laparotomy.  2. The sensitivity and specificity of physical exam was higher than that of CT imaging, and were more likely to alter clinical decision making than CT imaging.  Evidence Rating Level: 1 (Excellent) Study...
Image: PD 1. Approximately half (47%) of parents surveyed were aware that ionizing radiation from head computed tomography (CT) scans could increase their child’s risk of cancer, although 63% underestimated the risk. 2. Almost all (90%) parents wanted to be informed of potential risks of ionizing radiation from diagnostic tests before...
Image: CC/L. academia 1. The Canadian CT Head Rule consists of 7 predictor variables to assess the need for CT imaging in patients with minor head injuries. 2. This study demonstrates that the rule is highly sensitive and may help to reduce the number of CT scans ordered. Study Rundown: The Canadian CT...
