Critique and discussion of “Multicenter evaluation of frequency and impact of activity infiltration in PET imaging, including microscale modeling of skin-absorbed dose”

On May 25, 2023, the Journal of Nuclear Medicine (JNM) published an article ahead-of-print entitled “Multicenter Evaluation of Frequency and Impact of Activity Infiltration in PET Imaging, Including Microscale Modeling of Skin-Absorbed Dose” … There are, however, several problems with the work that raise questions about its conclusions. The methods are not well described, the results contain errors, and the peer-review process for this manuscript appears to have lacked rigor. Full Text

Radiopharmaceutical extravasations: a twenty year mini-review

This mini-review will examine the literature of the last twenty years to summarize the history of radiopharmaceutical extravasations, determine key trends in imaging and therapies, and highlight critical gaps in research that currently exist. Full Text

The decision to reimage following extravasation in diagnostic nuclear medicine

To provide high quality service, nuclear medicine departments as well as the interpreting radiologist physicians should be cognizant of the possible need to repeat studies which have been affected by an extravasation. Full Text

Active monitoring improves radiopharmaceutical administration quality

Our findings suggest that active monitoring and the associated display of results are critical to quality improvement efforts to reduce and sustain radiopharmaceutical extravasation rates. Full Text

Transparency – a patient-centric view on radiopharmaceutical extravasations

From the patient perspective, transparency regarding extravasations is essential to improving care, ensuring radiation protection, reducing health inequities, and untangling the deeply disturbing and irregular relationship between the nuclear medicine community and their regulating body, The U.S. Nuclear Regulatory Commission.

Lucerno Dynamics Submits ‘Information Correction Request’ to Address NRC Extravasation Reporting Decision

Lucerno informed the US Nuclear Regulatory Commission (NRC) that a key document used to develop the patient injury reporting criterion did not meet NRC’s requirements for information quality. Asks NRC to immediately issue Interim Staff Guidance. Press Release

Extravasation of radiopharmaceuticals: Why report?

Steps can be taken by radiation protection personnel at medical institutions to educate practitioners and staff about extravasations, their risks and what steps can be taken to reduce their occurrence. Further research needs to be performed to better understand the incidence rate, categorization, causes, and methods of prevention. Full text

NRC Commences Rulemaking to Close Loophole in Nuclear Medicine Safety

U.S. Nuclear Regulatory Commission accepts Lucerno’s petition for rulemaking and directs the commencement of a rulemaking process to close an outdated loophole in nuclear medicine safety regulations. Press Release

Practical Tools for Patient-specific Characterization and Dosimetry of Radiopharmaceutical Extravasation

Accurate extravasation dosimetry requires characterization of the event. In this work, we developed three extravasation characterization and dosimetry tools, validated each against published data, and demonstrated their utility in a realistic clinical workflow. Full Text

Development of a classifier for [18F] fluorodeoxyglucose extravasation severity using semi-quantitative readings from topically applied detectors

The topical detector binary classifier, calibrated using quantitative static PET measurements, significantly improves extravasation detection compared to qualitative image analysis. Full Text

House-Passed Appropriations Bills Advance Nuclear Medicine Safety, Transparency

Lucerno announced that Fiscal Year 2023 bills passed this week by the U.S. House of Representatives include critical language to improve the safety of nuclear medicine treatments and increase transparency within the American healthcare system. Press Release

Extravasation Reporting Pros and Cons

In 2020 the Health Physics Society (HPS) submitted a public comment, unsupported by science, to the Nuclear Regulatory Commission regarding the reporting of extravasations. In early 2022, the radiation protection journal, Health Physics, provided a forum for discussing the HPS public comment. Lucerno, patients, experts, and HPS members provided written responses to the HPS public comment.
