Utility of computed tomography angiography in traumatic lower limb injury: Review of clinical impact in level 1 trauma centre.

Introduction: CT angiography (CTA) is efficient and accurate in detecting lower limb vascular injury in the setting of trauma (1-6). Less clear is the in-practice correlation between appropriate indications for these examinations and subsequent clinical impacts.

Materials And Methods: All CT leg angiography acquired from January 2016 through April 2019 were reviewed via retrospective search.

Weight-Adjusted Contrast Administration in the Computed Tomography Evaluation of Pulmonary Embolism.

Introduction: Computed tomography pulmonary angiogram (CTPA) is widely considered the gold standard for diagnosis of pulmonary embolism (PE) with previous studies demonstrating high sensitivity and specificity. Despite this, nondiagnostic and indeterminate CTPA rates of 5%-26% remain a concern. As part of a continuing quality assurance program, a new weight-adjusted contrast dose and increased administration rate CTPA protocol was studied with an aim to improve diagnostic accuracy of PE evaluation.
