Related Imaging Modalities
Combine with CT/MRI/US for complementary detail.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.

Obstructive Uropathy Scan
Delayed tracer transit from renal pelvis to ureter and bladder. Dilated collecting system with cortical retention. Persistent pelvic activity with delayed or absent bladder visualization. Diuretic (lasix) response shows impaired washout.
Renal Artery Stenosis Scan
Decreased tracer uptake and delayed peak activity in the affected kidney. Delayed washout with persistent parenchymal activity after ACE inhibitor. Differential function shows decreased contribution from stenotic kidney. Normal kidney shows preserved uptake and washout.
Renal Function Scan
Radiotracer uptake and excretion patterns reflecting glomerular filtration and tubular function. Quantitative measures include differential renal function, GFR estimation, and excretion curves. Normal kidneys show prompt uptake and excretion.
