Data synthesis: Fifteen studies met the inclusion criteria and contained a total of 3500 patients who were evaluated from October 1994 through April 2002. To calculate the overall negative likelihood ratio (NLR) of a VTE after a negative or inconclusive chest CT scan for pulmonary embolism, we included VTEs that were objectively confirmed by an additional imaging test despite a negative or inconclusive CT scan and objectively confirmed VTEs that occurred during clinical follow-up of at least 3 months. Data extraction: Two reviewers independently abstracted patient demographics, frequency of venous thromboembolic events (VTEs), CT modality (single-slice CT, multidetector-row CT, or electron-beam CT), false-negative results, and deaths attributable to pulmonary embolism. Study selection: We included studies that used contrast-enhanced chest CT to rule out the diagnosis of acute pulmonary embolism, had a minimum follow-up of 3 months, and had study populations of more than 30 patients. Data sources: The medical literature databases of PubMed, MEDLINE, EMBASE, CRISP, metaRegister of Controlled Trials, and Cochrane were searched for articles published in the English language from January 1990 to May 2004. Objective: To review studies that used a CT-based approach to rule out a diagnosis of pulmonary embolism. Insufficient sensitivity for peripheral pulmonary embolism is considered the principal limitation of CT. 2007, vol.135, n.4, pp.539-543.Ĭontext: The clinical validity of using computed tomography (CT) to diagnose peripheral pulmonary embolism is uncertain.

La caracterización de las lesiones congénitas normalmente se realiza mediante tomografía computarizada (TCMD) o resonancia magnética (RM) con contraste endovenoso y reconstrucciones 3D y en diferentes planos. Generalmente se detectan en el periodo prenatal/neonatal o primera infancia sin embargo algunas permanecen asintomáticas y son detectadas incidentalmente en la edad adulta.Įstas malformaciones tienen manifestaciones radiológicas características, aunque pueden simular otras patologías y son causa frecuente de error diagnóstico. Las malformaciones congénitas pulmonares son raras y pueden clasificarse en tres categorías: anomalías broncopulmonares, anomalías vasculares aisladas y anomalías combinadas vasculares y pulmonares.
