Historical normal-tissue tolerance

Recall the number.
Understand the context.

A ten-question study session built around historical TD 5/5 estimates published by Emami and colleagues. Practice recognition—then keep the limitations in view.

TD 5/5: Estimated 5% severe-complication risk within 5 years
Volume: Partial-organ fractions described in the historical table
Unit: Absorbed dose shown in centigray (cGy)

Study frame

Know what the table can—and cannot—tell you.

These values are historical, population-level estimates. They predate modern contouring, delivery, imaging, fractionation practices, and contemporary outcome modeling.

One best answer

Each prompt pairs one organ and volume fraction with three distinct doses.

Immediate rationale

Review the source fact after every choice before moving forward.
