Fig. 2. — V/Q scintigraphy techniques. (a) A planar V/Q scan performed in various planes on a gamma camera yields two-dimensional projections of complex three-dimensional (3-D) anatomy, akin to a radiograph. (b) A SPECT camera is a tomographic version of the gamma camera and can obtain slices through the body allowing for three-dimensional detail. (c) The data from the SPECT can be fused to a computed tomography scan to simultaneously visualize anatomy and physiology.
