Developments in multislice computed tomography scanners in terms of spatial and temporal resolution when compared to electron-beam computed tomography and invasive coronary angiography

Imaging modalities	Spatial resolution (mm)	Temporal resolution (ms)
EBCT	1.5-3.0	50-100
4-slice CT	1.0-1.25	250
16-slice CT	0.75	165-188
64-slice single-source CT	0.5-0.6	165
64-slice dual-source CT	0.5-0.6	75-83
256/320-slice CT	0.5-0.6	135-175
Invasive coronary angiography	0.2	20

CT: Computed tomography; EBCT: Electron-beam CT.
