The early detection and management of wrist fractures may avert potential complications and patient morbidity. Five cases are described in which radiographically-occult fractures were clearly demonstrated by magnetic resonance imaging (MRI). These fractures were seen on MRI as a low signal linear band on T1- and T2-weighted images, with surrounding increased signal intensity from bone marrow oedema on T2-weighted images. In one case, intense oedema obscured the fracture line on the initial MR scan. MRI is useful in confirming the presence of a fracture, delineating its exact shape and location, and in the follow-up of these injuries during and after treatment.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
