病例报告:手术前放射学怀疑异型脑膜瘤:一个诊断挑战

Begin with a patient with meningioma, or a brain tumor, positioned in an MRI scanner for non-invasive brain imaging.Adjust the scanner to obtain structural images of individual slices of the brain.Enhance the contrast to improve tissue differentiation.Use interslice magnetization transfer ratio imaging on brain slices using radiofrequency pulses slightly offset from the MRI signal.The pulses deliver energy to the proton pool in macromolecules and bound water molecules.This energy transfers to...

Here, we present a protocol that manipulates interlocutor visibility to examine its impact on gesture production in interpersonal communication. This protocol is flexible to tasks implemented, gestures examined, and communication modality. It is ideal for populations with communication challenges, such as second language learners and individuals with autism spectrum...

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

A short clinical examination protocol is presented to aid in the detection of classical and atypical scrapie in sheep and...

Assessment of the EEG mu rhythm provides a unique methodology for examining brain activity and when combined with behaviorally based assays, can be a powerful tool for elucidating aspects of social cognition, such as imitation, in clinical...

This protocol presents the acetylcholine rechallenge after nitroglycerine as an add-on procedure to spasm provocation testing. The purpose of this technique is to unmask co-existing microvascular spasm in patients with epicardial spasm and to assess the protective efficacy of nitroglycerine on a per-patient level to guide medical...
