Obtained at 100 seconds to 120seconds after IV contrast injection, the timing for this contrast-enhancement phase is later than the typical portal venous phase, allowing for uniform enhancement of the renal parenchyma and in general providing the highest tumor to background distinction compared with the other phases ( Fig. 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.

The precontrast and nephrographic phase images are used to evaluate for changes of tumor size or enhancement characteristics in cases of active surveillance or detecting enhancing tumor in post-treatment settings ( Fig. MR imaging protocols should take advantage of the improved soft tissue contrast for renal tumor diagnosis and staging. 2001-2023 Oregon Health & Science University.

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.

In contrast, papillary RCCs demonstrate greater enhancement at later phases. 6qMo4#w4Q E The specifics will vary depending on MRI hardware and software, radiologist's and referrer's preference, institutional protocols . Computed tomography (CT) protocols for renal mass evaluation should be tailored to the clinical indications with careful considerations of balancing diagnostic accuracy and radiation dose. CT is the most commonly used modality for the detection and characterization of renal masses as well as presurgical planning and post-therapy surveillance. Contrast material is excreted into the renal collection system, ureters, and bladder in this phase, allowing better visualization of these structures. For patient comfort, if you.

The aim of this study is to investigate the feasibility of eliminating the nephrographic phase from the four-phase renal computed tomography (CT) imaging to a three-phase protocol without affecting its diagnostic value. The suggested imaging protocols are based on expert consensus, with the goal of balancing diagnostic efficacy and radiation exposure ( Table1 ). Although the specifics of a renal protocol CT vary by institutions, the following phases in their various combinations commonly are used: precontrast phase, corticomedullary phase, nephrographic phase, and excretory phase ( Fig. Pregnancy (risk vs benefit ratio to be assessed) Subscribe to Anesthesia Coder today. 0000031716 00000 n 1 0 obj Premedication Protocol. > carcinoma) 44 0 obj <> endobj The widespread use of cross-sectional imaging has led to a continuous increase in the number of incidentally detected indeterminate renal masses.
