Old Dog With New Tricks: 99mtc-Sestamibi Spect-Ct For Renal Mass Differentiation, Zachary Beswick, Ishani Dalal

Teaching and Education

Small renal masses have historically presented a diagnostic challenge for radiologists and urologists. MRI and CT have a limited capability to differentiate benign and malignant small solid renal masses. The relatively poor negative predictive value of renal biopsy limits the ability to avoid surgical resection in small renal masses with negative biopsy. 99mTc-sestamibi SPECT-CT can be an important tool in directing the management of patients with renal masses.We present the analysis of 99mTc-sestamibi uptake patterns in patients with small renal masses who underwent further characterization of these masses with 99mTc-sestamibi SPECT-CT. Pertinent interpretation points in differentiating renal cell carcinoma from …
