Are ultrasounds safe during pregnancy? Dr. Nivedita Singh, Consultant Obstetrician and Gynaecologist at Cloudnine Hospital, Jawahar Nagar, Jalandhar, explains why ultrasound is an important part of pregnancy care and addresses concerns about repeated scans. She explains that ultrasound uses sound waves rather than ionising radiation. She discusses the role of different pregnancy scans, including early pregnancy scans, the NT scan, the anomaly scan, and growth scans. She also explains why additional scans may be recommended in high-risk pregnancies and why your obstetrician should guide the timing and frequency of scans.
