The interobserver agreement between residents and experienced radiologists for detecting pulmonary embolism and DVT with using CT pulmonary angiography and indirect CT venography.

Objective: We wanted to prospectively evaluate the interobserver agreement between radiology residents and expert radiologists for interpreting CT images for making the diagnosis of pulmonary embolism (PE).

Materials And Methods: We assessed 112 consecutive patients, from April 2007 to August 2007, who were referred for combined CT pulmonary angiography and indirect CT venography for clinically suspected acute PE. CT scanning was performed with a 64x0.

Performance of the Wells and Revised Geneva scores for predicting pulmonary embolism.

Objective: The objective of the study was to compare two scoring methods to predict the risk of pulmonary embolism (PE) as diagnosed with computed tomography angiography (CTA) and/or CT venography (CTV).

Methods: Prospectively over a 8-month period, emergency department patients and hospital inpatients with suspected PE were consecutively examined and their Wells and Revised Geneva scores calculated to stratify them into a risk group for PE probability. Then all patients were examined with CTA and CTV to determine the presence or absence of PE, as diagnosed by experienced radiology staff physicians.
