How can artifacts influence nuclear medicine imaging results?

Artifacts in nuclear medicine imaging refer to any distortions or anomalies in the imaging results that do not originate from the intended anatomy or physiological processes being studied. When artifacts are present, they can mimic or obscure the actual signals from radiopharmaceutical distribution, leading to significant misinterpretation of results. For example, false-positive or false-negative findings may arise, which may lead healthcare providers to make inappropriate clinical decisions, such as unnecessary interventions or overlooking critical findings.

The presence of artifacts could be due to a variety of factors including patient movement, improper positioning, or the equipment itself. Each of these situations can generate misleading information that may be mistaken for pathological findings. Therefore, understanding the impact of artifacts is crucial for ensuring accurate diagnosis and patient safety in nuclear medicine.

Other options, while they may seem plausible, do not accurately reflect the primary concern with artifacts in imaging. Artifacts do not aid in diagnosis or provide additional helpful data; instead, they complicate the interpretation process. Furthermore, they do not eliminate the need for retakes; rather, they might necessitate repeated scans to achieve clear images for accurate diagnosis.
