A study ⁤published ‌in the Annals of Internal Medicine has reported associations​ between exposure to preconception ⁢computed ​tomography (CT) imaging with spontaneous pregnancy loss and congenital anomalies.¹

While CT ‌imaging is vital for disease diagnosis and surveillance, it has been ⁣linked to increased ionizing radiation ‌exposure, and use ​has ⁢significantly risen in the past 3 decades.‍ The⁤ ovarian follicle ‍has prolonged dormancy and a gradual maturation process, making it potentially more vulnerable.²

“Much less is known about ⁤pregnancy viability or the risk for a congenital anomaly‍ if exposure to CT⁤ ionizing radiation occurs well before conception,” wrote investigators.¹
