Description

We worked with two models—1in2 and 4 in2 FOV—of high-resolution hand-held cameras (HRCs), to verify if a HRC shows advantages over an Anger camera (AC) plus common gamma probe (GP). Methods: 280 patients with T1 breast cancer were divided in two groups of 140—one studied with AC-GP, the other with HRC. Patients were age, body mass index, and tumour size matched. Results: HRC detected more nodes than with GP+ AC: 247 vs 192 (p< 0.01). 45 nodes showed invasion in the HRC group, 32 in the AC+GP group (p =0.05). Conclusions: HRC shows clinically interesting advantages over AC-GP.
