Educational resource — not medical advice

The Nuclear Medicine Atlas is an educational and reference resource for clinicians, trainees, and students. It is not medical advice, does not establish a physician–patient relationship, and must not be used as the sole basis for any diagnostic or treatment decision. Clinical decisions remain the responsibility of the treating physician, exercised with independent judgment for the individual patient, in accordance with local protocol, current regulations, and the manufacturer's instructions for any radiopharmaceutical or device.

Verify against primary sources

Medicine changes, and errors are possible in any reference. Every clinically important statement should be confirmed against the primary literature, current society guidelines, and your institution's protocols before it informs care. Where this atlas grades evidence (A / B / C / INFERENCE), the grade signals the strength of the underlying support, not a guarantee — and "INFERENCE" explicitly marks reasoning where no study addresses the question directly.

The interactive tools are estimates

The calculators (dosimetry, patient release, activity prescription, and others) implement published formulas for educational estimation only. They do not account for every patient-specific factor, and their outputs are not a substitute for formal dosimetry, a qualified medical physicist, the Radiation Safety Officer, or your institutional procedures. Any activity administered, release decision, or dose calculation used in patient care must be independently verified and authorized by the appropriate qualified personnel.

No warranty

To the fullest extent permitted by law, the authors and contributors accept no liability for any loss or harm arising from use of, or reliance on, this resource. Use of the atlas constitutes acceptance of these terms.
