Radiation is ubiquitous in nature, and radiation is also widely used in various fields of medicine, agriculture, and industry. Current biological doses below 100 mSv are called low-dose radiation (LDR). Scientists have no consensus of effects on humans below this dose, so a variety of dose-response curve theories have been derived. ⋯ Nuclear molecular imaging is LDR, using different radionuclides or combining with specific ligands (carries) to form "radiopharmaceuticals" for functional or pathological evaluations of diseases. As an integral part of patient care, nuclear medicine is used in the diagnosis, management, treatment, follow-up, and prevention of diseases. Therefore, this paper discusses literature review and provides appropriate scientific data and communication to help the peers and the public understand its advantage and disadvantage.

Very few studies have focused on the correlation between structural heart disease and lower urinary tract symptoms. In this study, we applied echocardiography to explore the correlation between lower urinary tract symptoms and structural heart disease. ⋯ Moderate-to-severe lower urinary tract symptoms, especially storage symptoms, are an independent predictor of the co-existence of moderate-to-severe aortic regurgitation in women with cardiac symptoms. Early cardiological referral of patients with moderate-to-severe lower urinary tract symptoms and cardiac symptoms may improve their general health.

Postradiotherapy carotid vasculopathy is a clinically relevant complication in patients with head and neck cancer receiving radiotherapy. In this study, we investigated the factors associated with the development and progression of carotid artery stenosis (CAS) in such patients. ⋯ Modifiable vascular risk factors, such as hypertension and hypercholesterolemia, appear to be significantly associated with the rapid progression of postradiotherapy CAS in patients with head and neck cancer.
