Imaging modalities in pregnant cancer patients.

摘要: Cancer during pregnancy is increasingly diagnosed due to the trend of delaying a later age and probably also because increased use non-invasive prenatal testing for fetal aneuploidy screening with incidental finding maternal cancer. Pregnant women pose higher challenges in imaging, diagnosis, staging Physiological tissue changes related makes image interpretation more difficult. Moreover, uncertainty about safety imaging modalities, fear (unnecessary) radiation, lack standardized protocols may result underutilization necessary tests resulting suboptimal staging. Due absence radiation exposure, ultrasound MRI are obvious first-line modalities detailed locoregional disease assessment. has added advantage reproducible comprehensive organ or body region assessment, ability distant through whole-body evaluation, combination anatomical functional information by diffusion-weighted which obviates need gadolinium-based contrast-agent. Imaging inherent exposure such as CT nuclear should only be performed when benefit outweighs risk. The cumulative not exceed threshold 100 mGy. diagnosis likely guide change management. Radiologists play an important role multidisciplinary team order select most optimal strategies that balance risk treatment decisions. Our aim provide overview possibilities concerns current clinical applications developments patients cancer pregnancy.
