RT Journal Article SR Electronic T1 Uncommon congenital abnormalities and PET-CT imaging JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 1030 OP 1030 VO 50 IS supplement 2 A1 Ho, Linh A1 Wassef, Heidi A1 Shim, John A1 Seto, John A1 Henderson, Robert A1 Conti, Peter YR 2009 UL http://jnm.snmjournals.org/content/50/supplement_2/1030.abstract AB 1030 Learning Objectives There has been increasing utilization of PET-CT in patient management due to the increased diagnostic accuracy that hardware fused PET-CT affords compared to CT or PET alone. Some of these studies uncover unexpected findings. We present several cases of uncommon congenital anomalies discovered incidentally on PET-CT. Correct identification of these congenital anomalies is important to avoid misdiagnosis and unnecessary diagnostic studies and to alert the surgeon when the findings could alter the surgical approach. Summary: Review of these cases will help the nuclear physician increase his level of diagnostic confidence when encountering unexpected congenital anomalies on PET-CT.
