ANS: B

The sonographic appearance of the gastrointestinal tract is dependent on its contents. A fluid-filled lumen appears anechoic or echo free. A gas- or air-filled lumen will appear bright, highly echogenic, and generally hyperechoic relative to adjacent structures. The lumen can also have a complex or mixed appearance, displaying anechoic portions from fluid, along with echogenic portions that vary in brightness depending on their composition (partially digested food, indigestible material, gas, air). All or individual sections of the GI tract may cast a posterior shadow where air or gas is present in the lumen because air/gas attenuates the sound beam. Empty, collapsed bowel has a distinctive “bull's eye” appearance due to the contrast between the very bright collapsed lumen and dark/black walls.

OBJ: Contrast technical observation against the interpretive report.

TOP: How to Describe Ultrasound Findings 5.

In contrast, portal flow normally increases after ingestion of a meal, because of splanchnic vasodilatation and hyperemia, which are required to meet the metabolic demands of digestion.

the aortic bifurcation. b. The suprarenal abdominal aortic Doppler velocity waveform is triphasic because of the high resistance vascular bed of the fasting superior mesenteric artery. c. The kidneys and liver are high resistance end organs. d. A Doppler spectral waveform from the postprandial superior mesenteric artery demonstrates low diastolic flow because of the change in the vascular resistance of the stomach and small intestine that occurs with digestion.

ANS: A

The Doppler spectral waveform in the suprarenal aorta normally demonstrates constant forward flow throughout diastole to supply the low resistance vascular beds of the liver, spleen, and kidneys. The flow pattern in the SMA in the fasting state shows low diastolic flow, because this artery supplies the high resistance vascular bed of the stomach, small intestine, and colon. After ingestion of a meal, the metabolic demands of these tissues change; the level of vascular resistance must decrease for the tissues to receive increased oxygenated blood to remove the metabolic byproducts associated with digestion. For this reason, the Doppler spectral wave from the postprandial SMA shows high diastolic flow, characteristic of a low resistance vessel.

Blood flow to the normal kidney should demonstrate high diastolic flow. With intrinsic renal pathology the end-diastolic flow component decreases, and the waveform becomes markedly pulsatile.

The diencephalon is composed of three distinct structures: the thalamus, hypothalamus, and epithalamus. The thalamus serves as a relay station for upward-moving sensory impulses. As a result, we can experience a crude recognition of both pleasant and unpleasant sensations. The hypothalamus, lying under the thalamus, plays a role in regulating body temperature, fluid balance, and metabolism. Additionally, it functions as the center for such drives as thirst, appetite, and sex. The epithalamus lies midline and behind the third ventricle; it contains the pineal gland, which synthesizes enzymes related to daylight sensitivity.

TOP: Advanced Techniques in Breast Imaging 13. Elastography is a technique that improves sonographic visualization of tissues in fibrous breasts.

ANS: T Fibrous breasts have increased amounts of connective tissue and therefore increased echogenicity. Compression sonography is most helpful for assessing fibrous breasts, because it eliminates some of the posterior shadowing caused by the increased dense connective tissues. Incorporating palpation and compression, this technique has evolved into elasticity imaging, also known as strain imaging or elastography.

The normal increased diameter of the carotid bulb compared to the CCA results in a pressure-flow gradient on the posterolateral wall of the bulb (wall opposite the flow divide). Because blood will normally flow from high- to low-pressure regions, the flow stream within the bulb separates into forward flow entering the ICA and flow reversal near the posterolateral wall. This is known as boundary layer separation and characterizes the normal blood flow patterns in the carotid bulb.

Hydrostatic pressure increases a. the distance below the reference point increases. b. the distance above the reference point increase. c. if the limb is elevated. d. when the patient is supine.

ANS: A

Hydrostatic pressure is a physical characteristic of blood; it is related to the height of the column, the density of the fluid, and the gravitational force as it relates to the reference point of the right atrium. In a supine position hydrostatic pressure is negligible at 0-2 mmHg at this reference point. In the standing position hydrostatic pressure increases due to the increase in the weight of the column of blood within the vessel. The greater the distance below the reference point, the higher the hydrostatic pressure. Conversely, at a point above the reference point, such as elevating a limb, hydrostatic pressure will decrease.

Anisotropy is an artifact a. that occurs when the beam is parallel to a linear structure. b. that has little effect on imaging and diagnosis of musculoskeletal ultrasound

ANS: C Test bank Sonography Introduction to Normal Structure and Function 5th Edition by Curry Reva Prince Marilyn

Test bank Sonography Introduction to Normal Structure and Function 5th Edition by Curry Reva Prince Marilyn

One artifact unique to MSK sonography is anisotropy. When the ultrasound beam is not perpendicular to a linear structure, such as a tendon or ligament, echoes are not transmitted to form the entire image of the anatomy. Because of the linear nature of much musculoskeletal anatomy, anisotropy can largely affect a diagnosis if one is not aware of how to manipulate the sound beam to image the entire structure. This artifact will appear as if there is a defect in the anatomy because of the lack of beam transmission. To prevent misdiagnosis, the sonographer must learn to use probe manipulation to align completely perpendicular to the anatomy.
