10 Evidence-Based Tools for Clinical Decision Support

☢️Radiation Safety (2)

Convert CT Dose Length Product (DLP) to effective dose (mSv) for patient counseling and dose tracking. Essential for ALARA principles.

Calculate appropriate CT dose reduction for pediatric patients based on age and weight. Prevent unnecessary radiation exposure.

Calculate estimated Glomerular Filtration Rate to assess renal function before IV contrast administration. Prevent contrast-induced nephropathy.

Calculate appropriate iodinated contrast volume based on patient weight and concentration. Optimize image quality while minimizing risk.

Calculate gestational age and estimated delivery date from ultrasound measurements. Critical for African maternal health.

Estimate fetal weight from ultrasound biometry. Detect IUGR and macrosomia. Essential for delivery planning.

Canadian CT Head Rule: Determine need for head CT in minor head injury. Reduce unnecessary radiation in African emergency departments.

Risk stratify patients with PE to guide disposition. Low-risk PE may avoid admission in resource-limited settings.

Quick reference to ACR Appropriateness Criteria for evidence-based imaging selection. Reduce inappropriate imaging.

Standardized breast density classification for mammography reporting. Guide supplemental screening decisions.
