What is a common consequence of improper timing during contrast imaging?

Underexposure of images

Overexposure of images

Artifacts in the images

Improper timing during contrast imaging often leads to artifacts in the images. Artifacts can manifest as distortions or anomalies that detract from the clarity and accuracy of the images obtained. These artifacts can be a result of factors such as the timing of contrast media injection relative to image acquisition, which can lead to uneven distribution of the contrast agent or inadequate enhancement of the structures being examined. When the timing is poorly synchronized, the resulting images may exhibit streaks, shadows, or other irregularities that impair diagnostic quality.

The presence of artifacts can obscure important anatomical details, making it challenging for radiologists and clinicians to interpret the results accurately. Therefore, ensuring appropriate timing in the procedure is crucial for obtaining high-quality images that contribute to effective diagnosis and treatment planning.
