OBJECTIVE To determine the positive predictive value of International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) discharge codes for acute deep vein thrombosis or pulmonary embolism. MATERIALS AND METHODS Retrospective review of 3456 cases hospitalized between 2005 and 2007 that had a discharge code for venous thromboembolism, using 3 sample populations: a singl...

Within the traditional Hilbert space formalism of quantum mechanics, it is not possible to describe a particle as possessing, simultaneously, a sharp position value and a sharp momentum value. Is it possible, though, to describe a particle as possessing just a sharp position value (or just a sharp momentum value)? Some, such as Teller [22], have thought that the answer to this question is No — ...

ANB angle & Wits value are used to asses the Sagital pattern of the patient cephalometrically. The two variables are dependent on change in the Antero-posterior & vertical position of Point A. SNP plane angle determines the rotation change in position of Palatal plane with reference to SN plane. This rotational change might have an impact on the position of point A and thus the ANB angle and wi...

As health care moves to value orientation, radiology's traditional business model faces challenges to adapt. The authors describe a strategic value framework that radiology practices can use to best position themselves in their environments. This simplified construct encourages practices to define their dominant value propositions. There are 3 main value propositions that form a conceptual tria...
