28 sie 2023 · The nuclear renal scan, also known as renal scintigraphy, is an imaging method that uses radiopharmaceuticals/radiotracers to evaluate renal anatomy, physiology, and pathology. The various injected radiotracers are extracted from the blood by the kidneys and emit radiation, particularly gamma radiation, that is detected by gamma cameras.
17 lut 2023 · Acute tubular necrosis is characterized by renal tubular cell damage and death and is usually caused by ischemic or nephrotoxic insults. Deposition of cellular debris within the tubules results in oliguria. Urine microscopy for renal tubular epithelial cells and granular casts may be helpful to confirm a diagnosis.
form renal scans can be divided into three major categories: filtered by the glomerulus, secreted by the tubules, and retained in the tubules via receptor-mediated endocytosis.
30 sie 2018 · Functional agents (filtered by the glomerulus and/or secreted by the tubules) are used in the dynamic renal scan (renography), and morphological agents (retained in the tubules) are used in the static (cortical) renal scan.
14 lip 2024 · Renal imaging in nuclear medicine is a method to assess the kidneys and collecting systems via multiple different radioactive tracers. Dynamic renal imaging is performed using Tc-99m MAG3 or Tc-99m DTPA, and static renal imaging is performed with Tc-99m DMSA.
1 maj 2014 · A renal scan may provide complementary information regarding obstruction or a urine leak, and ACE inhibition renography can detect renovascular hypertension ; however, a renal scan cannot reliably distinguish between rejection and calcineurin-inhibitor nephrotoxicity.
14 lip 2023 · A DMSA scan is a static nuclear medicine study that indicates functioning renal tubular mass. It can be used to detect renal parenchymal abnormalities and to measure relative kidney function. This chapter describes how the DMSA scan is performed and how the result can be interpreted. Indications.
