How we measure drafts

Every MyRadAgent draft is reviewed, edited and signed by a radiologist. The figures on this page come from those signed reports: how much of each draft survived, how many were signed without any change, and how that has moved over time. The method and its limits are stated next to the numbers, and the page is recomputed from the database rather than written by hand.

Method

What a pair is

One report with the AI draft and the text the radiologist actually signed. Reports that were never confirmed are not pairs and do not count either way.

What “changed” means

The share of the draft’s characters that differ from the signed text, whitespace-normalized, computed with a standard sequence-matching ratio and capped at 10,000 characters per text. A two-word fix on a 300-word draft is about a 1% change; retyping the impression is a large one. “Signed unchanged” is the stricter count: any edit at all puts a pair in the edited group.

What is excluded

Pairs where the input and output describe different studies (a swapped case), pairs where the radiologist discarded the draft and signed the pasted dictation instead, gold-standard reports entered by hand (no draft to compare), and system-generated re-drafts whose change is not a radiologist’s edit. Excluding the discarded drafts makes the retention figure higher than it would be with them; the edited count below is not affected by that choice.

What this is not

Not clinical accuracy. A draft the radiologist signed unchanged was judged acceptable by that radiologist; it was not checked against a reference standard, so nothing here is a sensitivity or specificity. It also says nothing about studies that were never run through the product.

Who the data comes from

Every account on the platform, but most of the volume comes from one practice. Per-study-type rows show only with at least 20 pairs. A group pilot measures its own reports; ask for one from the pricing page.

What would be stronger evidence

A group pilot that measures its own before-and-after edit rates, turnaround and claim denials on its own reports. That is the comparison a department chair should ask for, and it is what the group pilot is set up to produce. The documentation savings estimator shows the cost side of that case with every assumption visible.

This is a reference implementation of a published guideline, for use by qualified clinicians. It does not account for patient-specific factors and is not a substitute for clinical judgment or a formal radiology consultation.
