Point-of-care ultrasound (POCUS) is an essential technique for screening for diaphragmatic dysfunction due to its portability, non-invasiveness, and real-time imaging capabilities. Although current diaphragmatic POCUS protocols exist, they suffer from poor interoperator reliability and lack consensus guidelines. Here we describe a technique that is reproducible and simple to perform.

Point-of-care ultrasound (POCUS) of the renal and genitourinary (renal-GU) system can help to screen for certain causes of kidney dysfunction. However, despite its clinical utility, renal-GU POCUS remains underutilized due to a lack of training among clinicians. To address this gap, this article describes renal-GU image acquisition and interpretation.

Point-of-care ultrasound (POCUS) of the optic nerve sheath diameter (ONSD) has been shown to be useful in identifying patients with increased intracranial pressure (ICP). However, the non-standardized technique for this POCUS has hampered its use. We present a standardized image acquisition protocol for use in the acute care setting.

FAQs
Echo timing helps place returning signals at appropriate image locations, while echo strength contributes to visible differences between reflecting tissue boundaries. Together, these signal characteristics allow the displayed image to represent internal anatomy rather than merely recording that sound returned. Their interpretation is therefore central to recognizing structures during clinical scanning.
Probe contact and orientation determine how effectively sound is transmitted into the body and how returning echoes are captured from the region of interest. Coupling gel supports sound transmission at the probe-body interface, while controlled positioning helps produce usable images. Poor contact, inconsistent positioning, or unsuitable orientation can reduce image quality and complicate interpretation.
Image quality depends on several controllable factors, including probe positioning, surface contact, orientation, and imaging-setting adjustments. These variables affect the clarity and usefulness of the displayed anatomy, so operators must coordinate them rather than rely on equipment settings alone. Careful control improves the likelihood that the resulting image can support accurate clinical interpretation.
A real-time display lets the examiner observe changing images while adjusting probe position, contact, orientation, and imaging settings. This immediate feedback helps guide the scan toward useful views and supports assessment as the examination proceeds. It also contributes to applications in bedside care and procedural guidance, where imaging must remain responsive to the clinical situation.
The workflow begins by placing coupling gel between the transducer and the body, then positioning the probe over the region of interest with appropriate contact and orientation. The operator observes the returning image and adjusts imaging settings as needed. These steps work together to obtain a clear, interpretable view of the targeted anatomy during scanning.
It is useful when clinicians need real-time visualization of organs, blood flow, or developing fetuses without ionizing radiation. Portability extends its value to bedside care, while live imaging supports procedural guidance. The same capabilities also make it relevant to clinical research, where investigators may need accessible visualization during examinations or interventions.
