Imaging in Gestational Trophoblastic Disease

Area of Science:

• Gynecology
• Radiology
• Oncology

Background:

• Gestational trophoblastic disease (GTD) encompasses a range of conditions from benign hydatidiform moles to malignant gestational trophoblastic neoplasia (GTN).
• Accurate diagnosis and monitoring are essential for effective management of GTD.

Purpose of the Study:

• To review the primary imaging modalities utilized in the evaluation of patients diagnosed with gestational trophoblastic disease (GTD).
• To highlight the role of various imaging techniques in diagnosing and staging GTD.

Main Methods:

• Review of current literature on imaging in gestational trophoblastic disease.
• Discussion of the applications of ultrasound, Doppler ultrasound, MRI, CT, X-ray, and PET/CT in GTD.

Main Results:

• Ultrasound is fundamental for diagnosing hydatidiform moles and plays a role in evaluating complications.
• Doppler ultrasound is the primary tool for confirming gestational trophoblastic neoplasia (GTN) diagnosis, with MRI useful in specific scenarios.
• A comprehensive metastatic workup for GTN involves multiple imaging modalities.

Conclusions:

• Imaging techniques are indispensable throughout the diagnostic and management pathway of gestational trophoblastic disease (GTD).
• The choice of imaging modality depends on the specific clinical context, from initial mole diagnosis to metastatic disease assessment.
