2019
This article presents a noninvasive biomonitoring system for the continuous recording and analyses of crayfish cardiac and locomotor activities. This system consists of a near-infrared optical sensor, a video-tracking module, and software for evaluating crayfish heartbeats that reflects its physiological condition and characterizes crayfish behavior during heartbeat fluctuations.
FAQs
Modality choice depends on the clinical information needed. Echocardiography uses reflected ultrasound waves, computed tomography uses X-rays, magnetic resonance imaging uses magnetic fields, and nuclear imaging uses injected tracers. These different physical signals allow clinicians to select an approach suited to assessing anatomy, motion, perfusion, blood flow, or tissue characteristics.
Structural and functional findings answer different diagnostic needs. Chamber size and congenital abnormalities describe anatomy, whereas wall motion, blood flow, and perfusion show how the heart operates. Tissue characteristics add another layer of information, helping clinicians assess cardiomyopathy alongside visible structural changes rather than relying on a single measurement.
Anatomical information shows what the heart looks like, while functional information shows how it behaves. Combining chamber size or congenital-structure assessment with wall motion, blood flow, or perfusion can give clinicians a more complete basis for evaluating cardiovascular disease. Tissue characteristics further extend assessment when cardiomyopathy is being considered.
A typical clinical workflow begins by identifying the cardiovascular question, then choosing a modality that can provide the relevant anatomical or functional information. The resulting study is examined for measurements such as chamber size, wall motion, blood flow, perfusion, or tissue characteristics. Findings then support diagnosis, risk assessment, treatment planning, or follow-up.
Clinicians use these studies when evaluating coronary artery disease, valve disorders, cardiomyopathy, or congenital abnormalities. The appropriate examination can provide anatomical information, functional measurements, or both, depending on the clinical need. Results support more than initial detection because they also contribute to cardiovascular risk assessment and decisions about treatment planning.
Imaging findings can guide treatment planning by showing relevant features of cardiac structure and function, including chamber size, wall motion, blood flow, perfusion, and tissue characteristics. The same range of information supports follow-up, allowing clinicians to reassess the heart after an initial evaluation and relate imaging results to ongoing cardiovascular care.
