SCIENTIFIC EXHIBIT |
1 From the Departments of Diagnostic Radiology (H.S., K.K., Y. Yuasa, A.T., K.H.), Pediatric Surgery (Y.M.), and Obstetrics and Gynecology (H.I., Y. Yoshimura), Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo 160-8582, Japan. Presented as a scientific exhibit at the 1999 RSNA scientific assembly. Received February 1, 2000; revision requested March 17 and received April 24; accepted April 25. Address correspondence to H.S. (e-mail: shinmoto@med.keio.ac.jp).
The recent popularity of prenatal magnetic resonance (MR) imaging has been associated with the development of ultrafast MR imaging techniques such as the single-shot fast spin-echo sequence. However, the majority of previous reports have concerned the fetal central nervous system (CNS) and chest disorders. MR imaging can demonstrate non-CNS fetal anatomy and pathologic conditions clearly. With its excellent tissue contrast, MR imaging provides information that supplements that provided by ultrasonography (US), especially in cases of neck, chest, and gastrointestinal lesions. Because of its large field of view, MR imaging allows evaluation of the relationship between a large lesion and adjacent structures. MR imaging should be considered if the diagnosis of a suspected non-CNS lesion is unclear at fetal US. MR imaging plays an important complementary role to US in cases of non-CNS fetal lesions and will be further accepted for fetal imaging in the future.
