With increasing utilization of cross-sectional imaging such as ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), the detection rates of an incidental kidney lesion have increased over time [].While most incidental kidney lesions can be left alone as they will have no clinical consequences, some are pathologies (eg, renal cell carcinoma, renal . Renal tumors are incidentally discovered at an increasing frequency due to the widespread use of cross-sectional imaging. (, Presurgical planning CT in a 65-year-old man with a left renal tumor. Given the indolent nature of papillary RCCs in general, these may be appropriate for active surveillance rather than surgical resection, especially in patients who are poor surgical candidates. ), T1 In-opposed phase breath hold axial 4mm.

(, CT in a 69-year-old man with a papillary RCC demonstrating improved enhancement assessment on the nephrographic phase compared with the corticomedullary phase. 1, 2 Many of these are 4 cm or less in diameter (clinical stage T1a) and termed small renal masses (SRMs). Check before giving contrast. This phase is helpful for identifying RCC involvement of the collecting system as well as diagnosing primary malignancy arising from the collecting system, such as urothelial carcinoma involving the kidney ( Fig. 0000008503 00000 n
Do not start scan until the patient has stopped breathing. Indeterminate renal mass, renal adenocarcinoma, metastasis, monitoring of known renal mass. > For the assessment of the inferior vena cava in patients with known solid renal tumour The corticomedullary and excretory phases together with the precontrast-phase and nephrographic-phase images may be helpful to subtype renal masses.

Do not start scan until the patient has stopped breathing. Measurement of HU change after contrast administration using the earlier corticomedullary phase in a papillary RCC may result in erroneous categorization of the lesion as a nonenhancing cyst (see Fig. Use T1 VIBE fat sat axial and coronal after the administration of IV gadolinium DTPA injection(copy the planning outlined above). Call 855-SAFE-RAD to schedule a radiology exam. 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.

The specifics will vary depending on CT hardware and software, radiologists' and referrers' preference, institutional protocols, patient factors (e.g. 1 ) 99% of the time.

In order to optimally visualize the small foci of fat, thin sections (eg, 1.25mm) may be required. MRA carotid with contrast. To plug inpatient facility revenue drains, subscribe to DRG Coder today. Diphenhydramine (Benadryl) (optional): 50 mg PO to be taken 1 hour prior to exam. The recommended dose of gadolinium DTPA injection is 0.1 mmol/kg, i.e. Renal masses usually are discovered incidentally on either a noncontrast-enhanced or a single-phase postcontrast CT obtained for unrelated indications.
