Image fusion of SPECT and PET data with CT and MRI has been shown to improve diagnostic accuracy in a variety of clinical circumstances. While the use of SPECT/CT and PET/CT image fusion has been well documented in the literature, there has been limited documentation of the role of planar image fusion. This brief pictorial review provides case examples where planar fusion between bone scintigraphy and xray has been useful.
Nuclear scintigraphy using single photon emission computed tomography (SPECT) provides functional information that is a valuable tool in the diagnosis of many diseases but is limited, on occasion, by less than ideal anatomic localization (
While the use of SPECT/CT (
A more useful application of planar fusion would be fusing orthopedic xrays with bone scintigraphy. Despite the apparent transparency of benefits, planar fusion between xray and bone scan has only once been reported in the literature (
Planar image fusion of bone scintigraphy and xray may provide a useful tool to improve diagnostic utility and / or interpretive certainty. The utility of xray fusion allows more precise anatomical reference to bone involvement. It is not uncommon for the combined image fusion data to provide additional clinical information that was not evident from either anatomic or functional datasets; interpreted in isolation or in tandem without fusion.
