Abstract

Single-photon emission computed tomography (SPECT) is frequently used with myocardial perfusion imaging in the assessment of patients with known or suspected coronary artery disease. The susceptibility of SPECT imaging to artifact, especially that caused by patient motion, has long been recognized. We report a characteristic artifact of patient motion, which we have termed the “hurricane sign” because of its similarity to the National Weather Service Symbol for a hurricane. This artifact is caused by varying contributions of different portions of the heart during image acquisition and their misalignment produced by patient motion.

    Motion artifact is often magnified by 2-headed cameras as there can be an abrupt shift in cardiac position between the last image of one head and the first image of the second head, as the images, although acquired with a relatively large time interval in between, are arranged in sequence in the unprocessed acquisition images. One characteristic sign of patient motion is the presence of distorted images with “tails” at the 12-o’clock and 6-o’clock positions on the short-axis slices, sometimes referred to as the “hurricane” sign as the image resembles the National Weather Service’s symbol for a hurricane, shown in Figure 4.51,52 Another potential source of acquisition-related error is cardiac image corruption by adjacent subdiaphragmatic activity.

    Motion may cause the following image artifacts on the reconstructed images: “hurricane sign,” distorted ventricular shape, and discontinuity of the ventricular walls. The hurricane sign8—in which the left ventricle in the short-axis views resembles the National Weather Service symbol for a hurricane—is caused by motion-induced smearing of photon counts in opposing directions around the left ventricle. Distortion of the ventricle so that the heart appears elongated or tilted, discontinuities of the left ventricular (LV) walls at the apex, nonanatomic defects, 12- and 6-o’clock defects, and hot spots are other characteristic patterns of motion artifacts.
