What is the typical sonographic echogenicity of the normal renal cortex compared to the liver?
Hyperechoic
Isoechoic
Hypoechoic
Anechoic
The renal cortex is usually slightly less echogenic compared to the liver, making it appear hypoechoic. This distinction helps differentiate cortical tissue from surrounding organs. Identifying this relative echogenicity is key in normal anatomy assessment.
Which transducer type is most appropriate for point-of-care renal ultrasound in adults?
Linear high-frequency probe
Curvilinear low-frequency probe
Phased array low-frequency probe
Endocavitary probe
A curvilinear low-frequency probe (2 - 5 MHz) offers deeper penetration needed for adult renal imaging. High-frequency linear probes lack sufficient depth, and phased array probes are optimal for cardiac exams. Endocavitary probes are not used for abdominal renal scanning.
In a standard transverse view of the kidney, the transducer marker is directed toward which side of the patient?
Head
Feet
Patient's right
Patient's left
For a transverse kidney view, the marker is usually oriented toward the patient's right side to maintain consistent left-right orientation on the screen. This standardization helps in comparing bilateral renal images. Reversing it can cause mirror-image confusion.
Which anatomic structure appears as an anechoic triangular area between the cortex and the sinus on ultrasound?
Renal pyramids
Collecting tubules
Renal pelvis
Perinephric fat
The renal pyramids are triangular, medullary structures that appear anechoic because they contain fluid-filled collecting ducts. They lie between the cortex and the echogenic sinus. Recognizing pyramids helps in assessing medullary anatomy.
The normal adult kidney is located between which vertebral levels?
T10 - T12
T12 - L3
L1 - L4
L3 - L5
The kidneys typically span vertebral levels T12 through L3, with the right kidney often slightly lower due to the liver. This retroperitoneal position is important when planning acoustic windows. Knowledge of location aids in probe placement.
What is the most likely ultrasound finding in a patient with mild hydronephrosis?
Cortical thinning
Anechoic dilation of the renal pelvis only
Medullary calcifications
Increased renal size with hyperechoic cortex
Mild hydronephrosis is characterized by dilation of the renal pelvis without calyceal involvement or cortical thinning. This early dilation appears as an anechoic area centrally. Recognizing mild cases guides further management.
On ultrasound, a simple renal cyst is characterized by which of the following features?
Internal septations
Anechoic with posterior acoustic enhancement
Hyperechoic solid lesion
Irregular wall and debris
A simple cyst appears completely anechoic and produces posterior acoustic enhancement due to fluid transmission of sound. It has a thin, smooth wall and no internal echoes. Complex features would suggest further evaluation.
What adjustment should be made to optimize visualization of the far field of the kidney?
Decrease depth
Turn off focal zones
Increase depth
Lower gain
Increasing imaging depth allows better visualization of deeper structures such as the renal hilum. Incorrect depth settings can truncate far-field anatomy. Proper depth optimization ensures the entire kidney is on screen.
Which of the following represents an imaging artifact and not a true anatomic structure in renal ultrasound?
Mirror artifact
Posterior acoustic shadowing
Acoustic enhancement
Anechoic renal pelvis
Mirror artifact occurs when sound reflects between strong reflectors and creates a false duplicate image. Shadowing and enhancement are true physical effects related to tissue composition. Recognizing mirror artifacts prevents misdiagnosis.
What is the normal thickness of the adult renal cortex on ultrasound?
< 5 mm
5 - 7 mm
7 - 10 mm
> 12 mm
Normal renal cortical thickness ranges from 7 to 10 mm. Measurements below 5 mm suggest chronic parenchymal disease. Accurate cortex measurement helps assess renal function.
Which description best defines moderate hydronephrosis on ultrasound?
Dilation of the renal pelvis only
Dilation of pelvis and calyces without cortical thinning
Pelvic dilation with cortical thinning
Multiple parenchymal cysts
Moderate hydronephrosis involves dilation of both the renal pelvis and calyces, but cortical thickness remains preserved. Severe cases show cortical thinning. Grading hydronephrosis guides urgency of intervention.
For a longitudinal (long-axis) view of the kidney, the transducer marker should be oriented toward the patient's:
Head
Feet
Left side
Right side
In a longitudinal view, marker-to-head orientation aligns the scan plane with the kidney's long axis. This shows the superior-inferior dimension. Marker-to-feet would invert the image.
Which ultrasound feature is characteristic of a renal calculus?
Anechoic rounded structure
Hypoechoic mass with posterior enhancement
Hyperechoic focus with posterior acoustic shadowing
Isoechoic area with internal septations
Renal calculi appear as bright (hyperechoic) foci with clean posterior acoustic shadowing due to dense stone composition. Posterior enhancement is seen with fluid-filled structures, not stones. Shadowing distinguishes calculi from other lesions.
Increased renal cortical echogenicity on ultrasound most commonly indicates:
Chronic kidney disease
Acute cyst formation
Mild hydronephrosis
Normal finding
Increased cortical echogenicity often reflects chronic parenchymal disease, such as glomerulosclerosis or fibrosis. Acute cysts are anechoic, and hydronephrosis shows central dilation. Normal cortex is less echogenic than liver.
Which probe frequency range is most suitable for adult renal ultrasound?
2 - 5 MHz
7 - 12 MHz
5 - 10 MHz
10 - 15 MHz
A 2 - 5 MHz curvilinear transducer balances penetration depth and resolution for adult renal imaging. Higher frequencies offer better resolution but insufficient depth penetration. Lower frequencies may reduce image detail.
A focal area of reduced perfusion on color Doppler within the renal cortex most likely indicates:
Renal infarction
Simple renal cyst
Hydronephrosis
Acute pyelonephritis
Renal infarction produces focal areas of absent or reduced perfusion on Doppler imaging due to vascular occlusion. Simple cysts have no internal flow but are anechoic. Pyelonephritis often shows hyperemia or mixed flow patterns.
In a renal transplant evaluation, a resistive index (RI) above 0.7 is most concerning for:
Allograft rejection or obstruction
Normal perfusion
Venous thrombosis
Low urine output
An RI above 0.7 suggests increased intrarenal resistance, which may result from acute rejection, ureteral obstruction, or vascular compromise. Normal RI values are typically below 0.7. Venous thrombosis has different Doppler signatures.
When increasing the dynamic range on the ultrasound machine, the expected effect on image contrast is:
Decreased contrast
Increased contrast
Greater penetration
Reduced speckle artifact
A higher dynamic range adds more gray-scale levels, which reduces overall image contrast and produces a smoother appearance. This can help visualize subtle tissue differences but may obscure small lesions. Contrast adjustment is key for pathology evaluation.
Which acoustic window is most appropriate for imaging the left kidney in a supine patient?
Splenic window in the left flank
Hepatic window in the right flank
Subxiphoid window
Suprapubic window
The spleen provides an excellent acoustic window to image the left kidney through the left flank, especially when the patient is supine. The hepatic window is used for right kidney imaging. Subxiphoid and suprapubic windows do not visualize the left kidney well.
Which ultrasound finding is most indicative of high-grade renal obstruction?
Cortical parenchymal thinning with calyceal dilation
Pelvic dilation only
Small echogenic stone without dilation
Multiple simple cysts
High-grade obstruction leads to both calyceal dilation and thinning of the cortical parenchyma due to prolonged pressure. Pelvic dilation alone suggests mild obstruction. Early detection of cortical thinning is critical for intervention.
