What is evidence-based practice in radiology?
Evidence-based radiology is defined as the decision that results from integrating clinical information to select the most appropriate imaging test on the basis of the best available evidence, the physician’s experience, and the patient’s expectations.
Is CT contrast toxic?
Contrast toxicity presents in a variety of ways, including increased serum creatinine, allergic reactions, and hemodynamic instability. If a patient is demonstrating symptoms of contrast toxicity, immediately cease administration of the contrast agent then treat with intravenous hydration and steroid.
When is IV contrast needed for CT?
CT scans of the brain: when is IV contrast used? IV contrast is used in brain CT when performing a CT angiogram (or venogram) or for evaluating an abscess or malignancy. In general, workups start with a non-contrast brain CT study and then may progress to MRI or contrast enhanced CT when necessary.
When should you not use IV contrast?
Contrast is not used in patients with head, extremity or spine trauma. It is also not used in patients with suspected acute stroke. Finally, imaging of the abdomen and pelvis to assess for renal stones also does not require CT contrast.

Is IV contrast used in radiotherapy planning?
This article reports on a UK survey of radiotherapy centres. The primary aim was to define the extent and range of practice for which intravenous (IV) contrast is used within radiotherapy planning (RTP) Computerised Tomography (CT) scans, including how well centres adhere to RCR guidelines (2004, 2010).
Does the evidence-based practice framework support robust decision making?
The evidence-based practice ( EBP) framework is widely accepted as a paradigm that supports robust decision making.
What is evidence-based radiology and why does it matter?
Evidence-based radiology should lead to evidence-based remuneration and could potentially counter some arbitrary percentage limits on recommending extra imaging tests. The principles are well established.
What is the value of EBP in radiology?
The potential value of EBP in any residency program or radiology department is outlined, including its use in formulating robust diagnostic and interventional strategies, its contribution to pre- and postcertification professionalism, and its incorporation into clinical decision support systems in the evolving health care environment.
