Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The simplest ophthalmoscopes consist of an aperture to look through, a diopter indicator, and a disc for selecting lenses. The ophthalmoscope is primarily used to examine the fundus, or the inner wall of the posterior eye, which consists of the choroid, retina, fovea, macula, optic disc, and retinal vessels (Figure 1). The spherical eyeball...

Transabdominal ultrasound is described as an effective, noninvasive means for assessing reproductive status in Reeves' muntjac deer. These methods can be used to achieve early pregnancy diagnosis and to evaluate fetal viability. Future applications of this technique include estimation of gestational age and effects of maternal disease on fetal development.

Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle function.

We describe a new ultrasound-based vector tissue Doppler imaging technique to measure muscle contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities. This approach provides complementary measurements of dynamic muscle function and could lead to a better understanding of mechanisms underlying musculoskeletal disorders.

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

The system interprets when echoes return and how strong they are after sound pulses travel through tissues. Echo timing contributes information about the location of structures, while echo intensity reflects differences encountered within the body. Processing these signals produces views that can be updated in real time, allowing clinicians to observe anatomy and movement during assessment.
Doppler ultrasound evaluates blood flow by measuring changes in the frequency of returning sound waves. This provides information that conventional structural imaging alone cannot supply, because it addresses movement within blood vessels rather than only the appearance of tissues. Clinicians can therefore assess vascular structures and incorporate flow-related findings into diagnostic examinations.
Real-time imaging lets clinicians view changing anatomy rather than relying only on a static image. This dynamic capability supports assessment of moving structures and helps guide actions while an examination or procedure is occurring. It also makes ultrasound useful for point-of-care assessment, where immediate visualization can contribute to clinical decision-making at the patient’s location.
A major distinction is that ultrasound examination uses high-frequency sound waves rather than ionizing radiation. This characteristic supports its use when clinicians need repeated or bedside imaging without exposing the patient to ionizing radiation. The method remains particularly valuable for examining soft tissues, blood vessels, organs, and developing fetuses while providing immediate, dynamic views.
The examination can be directed toward organs, soft tissues, blood vessels, and developing fetuses. Its usefulness comes from combining structural visualization with, when needed, Doppler assessment of blood flow. Because the same general approach can address several anatomical targets, clinicians can apply ultrasound across diagnostic medicine and adapt the examination to the clinical question.
Ultrasound provides real-time views that can help clinicians guide a needle toward a selected target during a procedure. Continuous visualization supports alignment between the instrument and the anatomy being approached, rather than relying only on pre-existing images. This application extends the method beyond diagnosis, using dynamic imaging to support procedural accuracy and immediate anatomical assessment.
Ultrasound is especially useful for point-of-care assessment when clinicians need portable, relatively low-cost imaging that can be performed near the patient. Its real-time capability allows immediate examination of relevant organs, soft tissues, or vessels and can also support procedure guidance. These features make it practical for rapid clinical evaluation without requiring a fixed imaging location.
Clinicians use ultrasound examination to obtain real-time views of developing fetuses without ionizing radiation. The ability to visualize anatomy dynamically supports ongoing assessment rather than a single isolated image. This application illustrates how the method combines noninvasive imaging with repeatable clinical monitoring, while its portability and accessibility can support examinations in different care settings.
