Near-infrared spectroscopy (NIRS) is an emerging tool to assess testicular torsion. It can measure oxygen saturation 3-4 cm deep in the skin, is rapid (lasting 20 seconds), and is noninvasive. Aydogdu et al performed a small prospective study evaluating 16 adult patients with testicular torsion and found NIRS to be 100% sensitive and specific for torsion when compared with the contralateral testis. More studies are needed confirmation before this modality becomes available for clinical use. [40]
