The document discusses various conditions that can be imaged when evaluating the urinary tract, including acute and chronic infections, abscesses, tuberculosis, trauma, papillary necrosis, and reflux nephropathy. Imaging tests like ultrasound, IVU, CT, DMSA scan, and cystography are used to detect abnormalities in the kidneys, ureters, and bladder that could indicate these conditions. CT is particularly useful for evaluating renal trauma and abscesses.
