SLC6A3 and Parkinson disease: They enable crucial cardiac imaging using tracers like 99mTc for myocardial perfusion, facilitating cardiovascular function assessment.[141] Additionally, contemporary RPhs very effectively evaluate neurological diseases; e.g., 18 F‐Florbetapir enables accurate amyloid imaging for diagnosis of Alzheimer's disease, whereas 123 I‐FP‐CIT monitors dopamine transporters for monitoring of Parkinson's disease progression.[142,143] Advances in imaging, individualized dosimetry, and advanced targeting continue to advance patient care in these diverse clinical areas.
