Frequently Asked Questions

What is Rad GEM?

Rad GEM (Guidance. Evidence. Management.) is an advanced clinical decision support tool designed for radiologists and technologists. It uses an AI to generate evidence-based, patient-specific CT scan protocols with a focus on optimizing image quality while adhering to the ALARA (As Low As Reasonably Achievable) principle for radiation dose.

What is the difference between Dual Source and Dual Energy?

Dual Source (DS) refers to a CT scanner with two X-ray tubes. Its main advantage is speed, which is critical for freezing motion in cardiac imaging (CCTA). Dual Energy (DE) is an imaging *technique* that uses two different X-ray energy levels to differentiate materials (e.g., iodine vs. bone, uric acid vs. calcium). A DS scanner *can* be used to perform DECT, but for some scans like CCTA, it's used in single-energy mode just for speed. Some single-source scanners can also perform DECT using rapid kV-switching.

How does the AI get its information?

The AI's logic is grounded in evidence. It cross-references its recommendations against guidelines from major radiological societies like the American College of Radiology (ACR), RSNA, and ESR, as well as data from peer-reviewed, PubMed-indexed studies. This is why you see citation tags on the recommendations.

Is the radiation dose estimate accurate?

The CTDIvol and DLP values are **heuristic estimates**, not precise physics calculations. Their primary purpose is to provide a clinically relevant, ballpark figure to help you compare the relative dose impact of different protocol choices (e.g., a conventional vs. a Dual Energy scan). The actual dose will be calculated by the CT scanner itself.
