005 Urinary Tract Imaging - Basic Principles of Nuclear Medicine Flashcards
The most commonly used radiopharmaceutical agents for nuclear imaging of the kidneys are: __, __. and __.
The most commonly used radiopharmaceutical agents for nuclear imaging of the kidneys are: 99MTC-DIETHYLENETRIAMINEPENTAACETIC ACID (99mTc-DTPA), 99MTC-MERCAPTOACETYLTRIGLYCERINE (99mTc-MAG3). and 99MTC-DIMERCAPTOSUCCINIC ACID (99mTc-DMSA).
__ and __ are used to measure renal blood flow, determine differential renal function, and to evaluate for the presence and degree of renal obstruction.
99MTC-DTPA and 99MTC-MAG3 are used to measure renal blood flow, determine differential renal function, and to evaluate for the presence and degree of renal obstruction.
99mTc-DTPA is cleared by __, whereas 99mTc-MAG3 is cleared by __.
99mTc-DTPA is cleared by GLOMERULAR FILTRATION, whereas 99mTc-MAG3 is cleared by TUBULAR SECRETION.
__ is the preferred at most centers over 99mTc-DTPA because it has a higher extraction efficiency and is less impacted by changes in renal function.
99MTC-MAG3 is the preferred at most centers over 99mTc-DTPA because it has a higher extraction efficiency and is less impacted by changes in renal function.
__ is retained by cells of the proximal renal tubules and is used to evaluate for infection and the presence of renal scarring.
99MTC-DMSA is retained by cells of the proximal renal tubules and is used to evaluate for infection and the presence of renal scarring.
__ AND __ can also be used to evaluate renovascular hypertension, transplant graft function, and vesicoureteral reflux.
99MTC-DTPA AND 99MTC-MAG3 can also be used to evaluate renovascular hypertension, transplant graft function, and vesicoureteral reflux.
Molecular imaging of cancer is most commonly performed using the positron emission tomography (PET) radiotracer __.
Molecular imaging of cancer is most commonly performed using the positron emission tomography (PET) radiotracer 2-DEOXY-2-(18F)FLUORO-D-GLUCOSE (18F-FDG).
A number of genitourinary malignancies can be successfully imaged with __, albeit with varying degrees of clinical utility beyond conventional anatomical imaging techniques.
A number of genitourinary malignancies can be successfully imaged with 18F-FDG PET, albeit with varying degrees of clinical utility beyond conventional anatomical imaging techniques.
Because 18F-FDG is excreted in the __, imaging with this radiotracer is typically performed to detect distant sites of disease.
Because 18F-FDG is excreted in the URINE, imaging with this radiotracer is typically performed to detect distant sites of disease.
18F-FDG has little role in imaging __, and a number of other radiotracers have been developed for this purpose.
18F-FDG has little role in imaging PROSTATE CANCER, and a number of other radiotracers have been developed for this purpose.
Radiotracers targeting __ are the most promising class of agents for prostate cancer imaging and in many parts of the world have become the new standard of care for imaging this malignancy.
Radiotracers targeting PSMA are the most promising class of agents for prostate cancer imaging and in many parts of the world have become the new standard of care for imaging this malignancy.
One of the most well-established indications for 18F-FDG PET imaging is in the detection of residual __ following chemotherapy.
One of the most well-established indications for 18F-FDG PET imaging is in the detection of residual SEMINOMATOUS GERM CELL TUMORS following chemotherapy.
