Most adrenal masses are detected first on abdominal CT scans, with an incidence of 0.6 to 1.3 percent on such scans.

Check for errors and try again. non-contrast scan is best to determine the HU of homogenous renal mass or masses containing macroscopic fat 1, corticomedullary phase is best to delineate subcategories of renal cell carcinomas further, nephrogenic phase is best for optimal enhancement of the renal parenchyma, including the renal medulla, and will demonstrate enhancing components of a mass, excretory phase will demonstrate enhancement of calyces, renal pelvis and ureters. > x]_s8OU&_6.IV=qcD ( @8nt7n\vysKw/seK?Dr)/bs9:_}? Patients with vomiting or dizziness with IV contrast or shellfish allergy do not require premedication. 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. Position the patient over the spine coil and place the body coil over the abdomen (xiphoid process down to anterior superior iliac spine) MR imaging serves as a problem-solving tool in renal mass evaluation, and MR imaging protocols should take advantage of its multiparametric capability to provide additional information for renal mass characterization. Adding a U prior to the IV makes the exam ultralow dose, o BCT 02UIV abd pelv w/IV contrast, ultralow dose. Call 855-SAFE-RAD to schedule a radiology exam. Optimized CT and MR imaging protocols enable analysis of imaging features that help narrow the differential diagnoses and guide management in patients with renal masses. 97 29 Similarly, on a single-phase postcontrast CT, renal masses that are homogeneous and measure fluid density are simple cysts. 3 0 obj 0000011681 00000 n Notes: Indeterminate adrenal lesions are typically discovered incidentally on contrast enhanced Nephrographic and excretory phases also are included, with the field of view expanded from diaphragm to iliac crest.

In the setting of advanced RCCs, tumor extension into the renal vain or inferior vena cava may be best assessed on the nephrographic phase as well. The renal mass CT protocol is a multi-phasic contrast-enhanced examination for the assessment of renal masses. IMG 238.

Enhancement patterns across different phases after IV contrast injection can be used to distinguish renal cysts from solid tumors and may aid in subtyping of renal tumors. > > > carcinoma) In this diagnostic procedure, the provider performs magnetic resonance imaging of a lower extremity joint without using contrast material.
