Protocol for a MULTI-centre feasibility study to assess the use of Tc-sestaMIBI SPECT/CT in the diagnosis of kidney tumours (MULTI-MIBI study).

Introduction: The incidence of renal tumours is increasing and anatomic imaging cannot reliably distinguish benign tumours from renal cell carcinoma. Up to 30% of renal tumours are benign, with oncocytomas the most common type. Biopsy has not been routinely adopted in many centres due to concerns surrounding non-diagnostic rate, bleeding and tumour seeding.
