The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
The kidney function can also be assessed with medical imaging. Some forms of imaging, such as kidney ultrasound or CT scans, may assess kidney function by indicating chronic disease that can impact function, by showing a small or shrivelled kidney. [citation needed].
A DMSA scan is a radionuclide scan that uses dimercaptosuccinic acid (DMSA) in assessing renal morphology, structure and function. Radioactive technetium-99m is combined with DMSA and injected into a patient, followed by imaging with a gamma camera after 2-3 hours. [1]
The image generated by the ultrasound can help diagnose renal cell carcinoma based on the differences of sound reflections on the surface of organs and the abnormal tissue masses. Essentially, ultrasound tests can determine whether the composition of the kidney mass is mainly solid or filled with fluid. [49]
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
A hypertrophied renal column (or renal pseudotumor) may be differentiated from an actual renal tumor with the help of a DMSA scan. The scan will show the area as one with normal activity if it is a pseudotumor or will show decreased uptake if it is a cystic or solid renal mass.
The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...
These outlines eventually come together to form a dense mass. [3] During its early stages, nephrocalcinosis is visible on x-ray , and appears as a fine granular mottling over the renal outlines. It is most commonly seen as an incidental finding with medullary sponge kidney on an abdominal x-ray.
