Imaging of Neurologic Disorders in Pregnancy

Area of Science:

• Neurology
• Radiology
• Obstetrics

Background:

• Pregnant women can experience worsening of existing neurological conditions or new symptoms.
• Neurological symptoms during pregnancy necessitate careful diagnostic evaluation.

Purpose of the Study:

• To outline the appropriate use of neuroimaging in pregnant patients.
• To guide diagnostic strategies for neurologic disorders during pregnancy and the peripartum period.

Main Methods:

• Review of clinical presentations and imaging findings in pregnant women with neurologic symptoms.
• Emphasis on Magnetic Resonance Imaging (MRI) as the preferred modality.
• Guidelines for avoiding ionizing radiation and contrast agents.

Main Results:

• Primary headaches in early pregnancy typically do not require imaging.
• Headaches in late pregnancy or peripartum, cerebrovascular complications, and enlarging mass lesions may require brain and/or spinal cord imaging.
• MRI is the preferred imaging technique during pregnancy.

Conclusions:

• Neuroimaging is crucial for diagnosing various neurologic disorders in pregnant women.
• The timing of pregnancy and specific symptoms dictate the need for imaging.
• MRI is the safest imaging choice, minimizing risks associated with radiation and contrast.
