Immediately after the contrast is administered, it appears on an X-ray as a 'renal blush'. This is the contrast being filtered through the cortex. At an interval of 3 minutes, the renal blush is still evident (to a lesser extent) but the calyces and renal pelvis are now visible.
It is most commonly seen as an incidental finding with medullary sponge kidney on an abdominal x-ray. It may be severe enough to cause (as well as be caused by) renal tubular acidosis or even end stage kidney disease, due to disruption of the kidney tissue by the deposited calcium salts.
A DMSA scan is usually static imaging, while other radiotracers like DTPA and MAG3 are usually used for dynamic imaging to assess renal excretion. [2] The major clinical indications for this investigation are Detection and/or evaluation of a renal scar, especially in patients having vesicoureteric reflux (VUR) Small or absent kidney (renal ...
Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling.A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. [1]
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].
Research on kidney transplants suggests that kidneys from donors with two copies of the higher-risk APOL1 variants fail at higher rates after transplantation. This could explain the data on Black ...
Contrast-enhanced renal ultrasonograph, showing a renal cell carcinoma successfully treated with thermal ablation, as no contrast enhancement is seen [1] Unspecific cortical lesion on CT is confirmed cystic and benign with contrast-enhanced renal ultrasonography using image fusion.
