A TIFFA scan, also known as Targeted Imaging for Fetal Anomalies, is a detailed ultrasound scan that is performed during pregnancy to check if the baby is growing normally and to detect any congenital abnormalities. It is usually performed between 18 and 22 weeks of pregnancy. During the scan, the baby is screened from head to toe to look for abnormalities, and the sonographer checks the babys organs, including the heart, brain, lungs, kidneys, abdomen, and face. The scan also measures and reports a number of things, such as the internal organs of the baby, the progress of the development of external organs, and the position of the placenta. The scan can be a 3-dimensional or 4-dimensional scan. The TIFFA scan is an important scan during pregnancy, and it helps the doctor to take necessary decisions to manage the rest of the pregnancy. The scan is an ultrasound scan, so the preparations are quite similar to the other scans, and the best practices are also the same - drink lots of water so that the bladder is full.
