Fetal brain imaging
October 03, 2005A modified technique that uses the eyes as the line of reference means a 50 percent reduction in the time necessary to take MRI images of the fetal brain.
"One of the challenges of imaging the fetal head is that the fetus can move during the study, so it is often difficult to obtain the three different imaging views that best show intracranial anatomy especially when study time is prolonged." said Keyanoosh Hosseinzadeh, MD, Chief of Body MRI at the University of Pittsburgh Medical Center, and lead author of the study. "When we draw a line of reference through the eyes, and subsequent imaging is performed along that plane, we can then rapidly acquire the three imaging planes," he said.
The total examination time, using the modified technique is now about 12 minutes, Dr Hosseinzadeh said. That compares to the standard technique that can take at least twice that long, he added.
"Fetal MRI is being increasingly performed because it provides an excellent view of the brain tissue and it doesn't use radiation," said Dr. Hosseinzadeh. It is usually performed when ultrasound is inconclusive or further information is required that may change the management of the pregnancy, he said.
"Although no deleterious effects have been noted from MRI to the unborn fetus, we make every effort to minimize exposure of the fetus to the electromagnetic field; we also want to reduce the total examination time for the mother while still obtaining the appropriate diagnostic images," said Dr. Hosseinzadeh. In the past, it took several attempts - almost in a hit and miss fashion - to obtain the diagnostic images needed. This technique allows us to avoid taking unnecessary images, he said.

MRI of the Fetal Brain: Normal Development and Cerebral Pathologies by C. Garel (Author), V. Delezoide (Translator), A.-L. Delezoide (Translator), L. Guibaud (Translator), G. Sebag (Translator), P. Gressens (Translator), M. Elmaleh-Bergès (Translator), M. Hassan (Translator), H. Brisse (Translator), E. Chantrel (Translator) Fetal MR has grown continually in importance in recent years, and the brain has become the main focus of investigation. However, we lack established standards and a good knowledge of the normal MR appearance. To fill this gap is the purpose of the first part of this book, which is an MR atlas of the cerebral development of the fetus. The second part is dedicated to cerebral pathologies. It includes, for each condition, a summary of the fundamental data, the imaging findings (US and MR) in correlation with neurofetopathology and/or postnatal imaging, and a brief perspective of the prognosis. |

Ultrasound and the Fetal Brain by F.A. Chervenak (Editor), A. Kurjak (Editor) This book presents original new data along with authoritative analyses and syntheses of all available clinical and research findings on using ultrasound, including color Doppler and magnetic resonance imaging, to examine and diagnose pathologies of, damage to, and anomalies of the fetal brain. It has eleven color plates of ultrasound and color Doppler scans, many black-and-white illustrations, and the largest collection of references ever published on ultrasound and the fetal brain. The contributing authors are the world's pioneering experts on ultrasound diagnosis in obstetrics and gynecology, whose work forms the backbone of modern clinical practice and research in this field. |

Atlas of Fetal and Postnatal Brain MR by Paul D. Griffiths FRCR PhD (Author), Janet Morris MSc (Author), Jeanne-Claudie Larroche MD (Author), Michael Reeves FRCR (Author) The Atlas of Fetal and Neonatal Brain MR is an excellent atlas that fills the gap in coverage on normal brain development. Dr. Paul Griffiths and his team present a highly visual approach to the neonatal and fetal periods of growth. With over 800 images, you'll have multiple views of normal presentation in utero, post-mortem, and more. Whether you're a new resident or a seasoned practitioner, this is an invaluable guide to the new and increased use of MRI in evaluating normal and abnormal fetal and neonatal brain development. Covers both fetal and neonatal periods to serve as the most comprehensive atlas on the topic.

Anomalies of the Fetal Head, Neck, and Spine: Ultrasound Diagnosis and Management by Frank A. Chervenak (Author), Glenn Isaacson (Author), John Lorber (Author) Using obstetric ultrasound to focus on the development of the neural system, this practical volume describes antenatal diagnosis of fetal defects. ACUSON scans provide high-quality, anatomical and ultrasonographic pictures, and are accompanied by clear and relevant textual descriptions by noted authors. These fetal anomalies are of considerable import because they often determine survival, physical appearance, and function in society. | |
