Safety of Magnetic Resonance Imaging in Pregnancy

Melanoma in Pregnancy-Diagnosis, Treatment, and Consequences for Fetal Development and the Maintenance of Pregnancy

Cutaneous malignant melanoma is one of the most common neoplasms among pregnancy-associated cancers (PACs). Risk factors include excessive exposure to ultraviolet radiation, the presence of benign and dysplastic nevi, and a patient or family history of melanoma. Self-examination and careful inspection of nevi are crucial, especially in the context of their progression over time. Physiological changes that occur during pregnancy, such as the darkening and enlargement of the nevi, delay the diagnosis of CMM. In the fetus, metastases are very rare, and if they do occur, they concern the placenta or fetal tissues. The choice of treatment is influenced by the cancer stage, symptoms, the time of termination of pregnancy, and the patient's decision. Essential procedures which are safe for the fetus are diagnostic biopsy, ultrasound, and the therapeutic excision of the lesion and the affected lymph nodes. Other imaging methods can be used with a safe radiation dose limit of 100 mGy. Immunotherapy and targeted treatments must be carefully considered, because of their possible adverse effects on the fetus. An interdisciplinary approach to the problem of melanoma during pregnancy is necessary, involving doctors of various specialties.

Patient experiences and anxiety related to medical imaging: challenges and potential solutions

Patients' experiences of medical imaging are varied. In referencing the work of Plunkett et al. https://doi.org/10.1002/jmrs.725, relating to fetal MRI, this editorial explores potential methods for increased education and support to alleviate anxiety in patients undergoing medical imaging procedures.
