When further work-up for a renal mass is deemed necessary, additional imaging can be obtained using a multiphase renal protocol CT. 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. , When the initial CT is unable to provide a definitive diagnosis, subsequent multiphase renal protocol CT after IV contrast injection commonly is obtained for further characterization of a renal mass. Scanner preference: 1.5T. endobj Check before giving contrast. Nephrographic phase is the most sensitive for detecting renal lesions.

The combination of these phases may be modified depending on the clinical indications, such as for initial lesion characterization, surgical or ablation planning, or post-treatment follow-up. Renal masses increasingly are found incidentally, largely due to the frequent use of medical imaging. 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. zb;5X/Cac Zvq\H2w;w;/~Ne#)*7!nG (]vS~(HakGK Z6M5f?CS e 4 0 obj % MSwnA) q%-#5Fms )fHde For example, a tumor with enhancement features that suggest a papillary RCC can be confirmed with percutaneous biopsy.

Unable to process the form. 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. Instruct the patient to hold their breath during image acquisition. Search across Medicare Manuals, Transmittals, and more. Computed tomography (CT) and MR imaging are mainstays for renal mass characterization, presurgical planning of renal tumors, and surveillance after surgery or systemic therapy for advanced renal cell carcinomas. 0000008946 00000 n > I can't find anything on the federal register stating p Read a CPT Assistant article by subscribing to.

MR imaging protocols should take advantage of the improved soft tissue contrast for renal tumor diagnosis and staging. A three plane TrueFISP localiser must be taken initially to localise and plan the sequences. Corticomedullary phase typically is acquired 40 seconds to 70seconds after IV contrast injection (see Fig. Adrenal glands protocol (MRI) | Radiology Reference Article > For the assessment of the inferior vena cava in patients with known solid renal tumour Diagnostic Radiology (Diagnostic Imaging) Procedures, Diagnostic Radiology (Diagnostic Imaging) Procedures of the Lower Extremities, Copyright 2023.
