Abstract Background Background: Parotid gland neoplasms occur near the facial nerve. Hence, it is crucial to determine whether the malignant neoplasms involve the facial nerve and whether sacrifice of the nerve in surgery is necessary. Furthermore, w

Magnetic resonance imaging (MRI) is an invaluable tool for the diagnosis and study of brain function. Central to the MRI system, the radio frequency (RF) coil plays a dual role: stimulating spins and receiving the MR signal, enabling the generation o

Cerebral blood flow (CBF) is a critical physiological parameter of brain health, and it can be non-invasively measured with arterial spin labeling (ASL) MRI. In this study, we evaluated and optimized whole-brain, high-resolution ASL as an alternative
