Similarly, on a single-phase postcontrast CT, renal masses that are homogeneous and measure fluid density are simple cysts. For FREE Trial. Indeterminate renal mass, renal adenocarcinoma, metastasis, monitoring of known renal mass. Arterial phase (approximately 30-second delay) with field of view focused on the kidneys is recommended to better depict arteries and their relationship to the renal tumor. I can't find anything on the federal register stating p Read a CPT Assistant article by subscribing to. This phase is helpful for identifying RCC involvement of the collecting system as well as diagnosing primary malignancy arising from the collecting system, such as urothelial carcinoma involving the kidney ( Fig. Ferromagnetic surgical clips or staples IV contrast generally is needed for the characterization, staging, surveillance, and post-treatment follow-up of renal tumors. Renal masses increasingly are found incidentally, largely due to the frequent use of medical imaging. For indeterminate renal masses, the field of view can be restricted to the kidneys only, with precontrast and nephrographic (obtained at 100-second to 120-second delay) phases considered essential for this indication. Instruct the patient to hold their breath during image acquisition. They vary widely in biological aggressiveness, ranging from benign tumors to high grade renal cell carcinomas (RCCs).
