MRI Human Embryo - Upper Limb
Human embryo week 6 (GA 8 week) and week 7 (GA 9 week). Ex vivo magnetic resonance microscopy (MRM) at 7.1 T (Clin Scan, Bruker Biospin, Germany) was performed in 10 human specimens at 8 to 12 weeks of gestational age (GA). In-plane resolution was 20 μm with a slice thickness of 70 μm.

Shows initial ossification within the central part of the diaphysis (arrow). Chondrified ribs (short arrow). | width=300pxShows small ossification centers in the central parts of the radius and ulna (arrow). The carpal (dotted white arrow) and metacarpal bones (dotted black arrow) are already visible as precartilage states. | Shows increased size of the ossification centers in humerus (white arrowhead) and radius (black arrow). The carpal and metacarpal bones demonstrate progressive chondrification and appear hypointense compared to the 8-week GA specimen |
