PET/MR imaging for the evaluation of cervical cancer during pregnancy

Abstract: Background Malignancy during pregnancy is increasing, and the most common type of malignancy is uterine cervical cancer. When planning the treatment of cervical cancer, it is important to look for signs of metastasis before surgery, especially metastasis to the lymph nodes. In this report, we assessed the diagnostic value of positron emission tomography/magnetic resonance imaging (PET/MRI) for evaluating cervical cancer propagation before surgery, with a focus on pregnant women. … Show more

“…21 Thus far, no long-term adverse effects related to chemotherapy exist but rather those related to premature birth, which also may occur in pregnant patients with cancer. 5,21,22 To evaluate cancer progression, although 18 F-fluorodeoxyglucose uptake as a result of positron emission tomography/magnetic resonance imaging (PET/MRI) has demonstrated fetal safety 23 and is considered effective in evaluating cancer progression in pregnancy, 24 doses as low as reasonably possible should still be applied. 25 Given how PET/MRI, the preferred imaging modality, may not be available worldwide, other ionizing radiation imaging modalities including computed tomography (CT) scans, PET/CT, and bone scintigraphy may be used as alternatives, with appropriate protective measures (fetal shielding and low-dose CT scan), on the basis of a review of imaging modalities in pregnant patients with cancer.…”

“…Data for seven of these 11 women were previously published in a study that sought to assess the clinical utility of 18 F-FDG PET in cervical cancer (6). The patients were treated at the Niigata University Medical and Dental Hospital, Niigata, Japan, and the imaging was performed at the Fukushima Medical University Hospital using a Biograph mMR PET/MRI device equipped with a 3-T MRI (Siemens Healthcare).…”

“…MRI can also be used as an alternative to US and CT for the diagnosis of cancer. Breast cancer is the most frequently diagnosed cancer in pregnant women [18,19]; other gynecological malignancies, such as cervical and ovarian cancer, or increasingly common colorectal cancers, may also prompt the need for MRI investigations [16,18,20]. This imaging system can also be applied in the evaluation of the brain, chest maternal diseases, musculoskeletal disorders, cardiovascular post-operative evaluation, and monitoring of congenital or acquired heart pathologies [21,22].…”
