Which three factors can cause image artifacts in CT imaging?

Image artifacts in CT imaging can arise from various factors that can compromise the quality and accuracy of the obtained images. Among these options, three significant contributors stand out.

Equipment failure can lead to issues such as malfunctioning detectors, calibration problems, or software malfunctions, all of which can produce artifacts in the final image. When any component of the CT machine does not function as intended, it can introduce noise, streaks, or other distortions, resulting in unreliable diagnostic information.

Patient movement during the exposure also plays a crucial role in the generation of artifacts. If a patient does not remain still during the scan, it can cause blurring or doubling of structures, making it difficult to interpret the images accurately. Motion artifacts can obscure critical details, affecting the overall diagnosis and treatment planning.

The incorrect contrast injection rate is another factor that can contribute to artifacts. If the contrast media is administered too quickly or too slowly, it may result in inconsistent enhancement of tissues. This inconsistency can create areas of non-uniformity that complicate image interpretation, making it hard to distinguish between normal and pathological findings.

In contrast, incorrect patient identification does not directly cause image artifacts. While it is crucial for ensuring that the correct patient is being scanned and receiving appropriate care,
