Short communication: MR imaging of fetal brain abnormalities using a HASTE sequence

Area of Science:

• Medical Imaging
• Radiology
• Fetal Medicine

Background:

• Fetal cerebral abnormalities require accurate and timely diagnosis.
• Ultrasound is a primary screening tool, but advanced imaging may be needed.
• Magnetic Resonance (MR) imaging offers detailed anatomical visualization.

Purpose of the Study:

• To evaluate the diagnostic utility of the HASTE sequence for fetal cerebral abnormalities.
• To assess the speed and quality of HASTE MR imaging in utero.

Main Methods:

• Utilized the HASTE (half-Fourier acquisition single-shot turbo spin echo) sequence for MR imaging.
• Studied five fetuses with suspected cerebral abnormalities identified via ultrasound.
• Compared in utero HASTE images with post-natal MR or CT scans for validation.

Main Results:

• HASTE MRI provided images of diagnostic quality in a very short scanning time.
• Correct diagnosis of fetal cerebral abnormalities was achieved in 4 out of 5 fetuses.
• The diagnosis was nearly accurate in the remaining fetus, indicating high sensitivity.

Conclusions:

• The HASTE sequence is a valuable tool for the rapid diagnosis of fetal cerebral abnormalities.
• Its ability to acquire high-quality T2-weighted images quickly makes it suitable for prenatal imaging.
• HASTE MRI can aid in improving the accuracy and efficiency of prenatal diagnosis.
