A growing collection of free, guideline-based decision tools for radiologists, referring physicians, and trainees. Each tool produces a structured recommendation in under a minute and links to the source guidelines. The same decision logic powers the Gantry radiology app on iOS and Android.
Iodinated Contrast & Thyroid
Guideline-based decision tool for iodinated CT contrast in patients with thyroid disease. Covers TSH screening, latent/manifest hyperthyroidism, sodium perchlorate premedication, amiodarone, radioiodine washout, and post-thyroidectomy.
Each tool is a decision aid and does not replace clinical judgement, institutional protocols, or specialist consultation. Final responsibility for the diagnostic decision rests with the treating physician.
Tools are maintained by Josh Decker, MD, a board-certified radiologist working in Germany. Feedback is welcome via the feedback button inside each tool.
