Sinogram utilization revisited

Abstract

With the many conventional radiographic imaging modalities available today, the sinogram is an often overlooked, but useful study that can help with the management of patients with sinus tracts that questionably involve the bone or joint. When MRI and CT do not sufficiently illuminate these infections, sinogram is a useful diagnostic modality. We present two patients in whom sinogram was used to evaluate the depth and extent of a sinus tract that questionably involved infectious bone or joint. In both patients, MRI failed to detect a sinus tract communicating with the joint. The patients subsequently had sinogram studies, which adequately established the location of the sinus tract involved.
