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. Thirty patients undergoing four-phase renal CT scans for assessment of renal lesions (>10 mm) were included in the study. Breathe the patient slowly so they have time to follow instructions. IV contrast material type, volume, and injection rate: type, low-osmolar or iso-osmolar contrast material; volume, 35-g to 52.5-g iodine equivalent (ie, for contrast material that contains 350mg of iodine/mL, the corresponding dose is 100150mL); and weight-based dosing injection rate, 25mL/s.

Oregon Health & Science University is dedicated to improving the health and quality of life for all Oregonians through excellence, innovation and leadership in health care, education and research. 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.

Similarly, precontrast CT also improves visualization of calcification ( Fig. JN The excretory phase allows better depiction of the relationship between the mass and the renal collecting system. Patients with anaphylaxis or laryngeal edema should be discussed with radiologist before the exam and/or premedication is ordered.

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. 1, 2 Many of these are 4 cm or less in diameter (clinical stage T1a) and termed small renal masses (SRMs). Check the positioning block in the other two planes. oncocytoma and angiomyolipoma) 6 ) or identify vascular anomalies, such as pseudoaneurysm and arteriovenous fistula. IMG 238. CT protocols should be tailored to different clinical indications, balancing diagnostic accuracy and radiation exposure. Renal masses increasingly are found incidentally during work-up for nonrenal indications, largely due to the frequent use of medical imaging. Trigger when contrast reaches SMA. ?,)NA For clinical responsibility, terminology, tips and additional info start codify free trial. 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. I agree with what t Radiologist is performing MRI RT foot and ankle - the report talks about both areas. Slices must be sufficient to cover both kidneys anterior to posterior. 1. 0000008946 00000 n Ask the patient to undress and change into a hospital gown Procedure code. It outlines all sequences and protocols currently applied in our MRI section. Contrast material is excreted into the renal collection system, ureters, and bladder in this phase, allowing better visualization of these structures. Within the next several years providers will be required to observe appropriate use criteria AUC as a condition of payment when reporting certain services for Medicare beneficiaries. 6qMo4#w4Q E <> Scanner preference: 1.5T 10 ). Planning must be done in the breath hold T1 vibe coronal because the diaphragm will push down the upper abdominal organs during inhalation and change the position of the kidneys from the initial localizer scans. These are fast single shot localisers with under 25s acqusition time which are excellent for localising abdominal structures. (, CT in a 57-year-old woman with a renal AML.

Protocol 1 Indications: Indeterminate renal mass Recommended scan series: Pre-contrast: kidneys only, axial, 3mm reconstruction section thickness with or without 50% overlap Nephrographic phase: kidneys only, axial, 3mm reconstruction section thickness with or without 50% overlap, at 100-120 second delay Optional additional scan series: 1 0 obj hbbd``b`@q+`a4A+$@>uwDA Q@t: <> MR imaging protocols should take advantage of the improved soft tissue contrast for renal tumor diagnosis and staging.

HCC Renal Mass or Cyst Transitional Cell Carcinoma of Kidney Increased Liver . 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. 2 AD). Recommended additional reformats: coronal and sagittal of each postcontrast scan series; 3-mm reconstruction section thickness without overlap. They vary widely in biological aggressiveness, ranging from benign tumors to high grade renal cell carcinomas (RCCs). The Society of Abdominal Radiology (SAR) Disease-Focused Panel (DFP) on RCC is a multi-institutional working group aimed at addressing the unmet needs in the clinical care, research, and education in RCCs.
