Qualitative study of nuclear medicine physicians' perceptions of positron emission tomography/computed tomography in pregnant patients with cancer.

Staging using positron emission tomography/computed tomography (PET/CT) is standard of care in many cancers that occur most frequently in pregnancy, particularly lymphoma. While expert guidelines generally recommend against PET/CT in pregnant women, there is emerging evidence that likely absorbed foetal doses in pregnancy are relatively low, and as such in certain circumstances PET/CT may be acceptable when balancing benefit and risk. We conducted a qualitative survey of nuclear medicine physicians in Australia and New Zealand to assess practice and attitudes with respect to PET/CT in pregnancy women, finding that most respondents considered PET/CT in pregnancy may be an appropriate modality in carefully selected clinical contexts with appropriate modifications. It is important to continue to define the role of PET/CT in pregnancy into the future, particularly as this imaging modality has emerged as the standard of care in staging and response assessment for many cancers.
