By applying enhancement thresholds, 1 study has shown that 4-phase CT attenuation profiles enabled differentiation of clear cell RCCs from other solid renal cortical masses, notably from papillary RCCs and lipid-poor AMLs. For example, a tumor with enhancement features that suggest a papillary RCC can be confirmed with percutaneous biopsy. For patient comfort, if you. 8 ). Radiographics.

In a click, check the DRG's IPPS allowable, length of stay, and more.

Imaging is essential in renal mass characterization in order to guide appropriate treatment selections, because the management paradigm of localized renal tumors has evolved in recent years to include active surveillance and thermal ablation in addition to partial and radical nephrectomy.
