Diffusion Tensor Imaging in the Diagnosis of Perianal Abscess: Protocol for a Single-Blind Randomized Controlled Trial

DTI technique can be used to gain a deeper understanding of the relationship between internal orifice, the degree of infected infiltration, the extent of the abscess, and the involvement of the perianal tissues and muscles in patients with perianal abscess. Deep pelvic floor DTI reveals the complex 3D structure of the pelvic floor in perianal abscesses through structured reports, which may provide new insights into the diagnosis of perianal abscesses.
