Photon-counting detector CT, a recent advance in CT technology, has several advantages over conventional energy-integrating detector CT. These include increased spatial resolution, reduced image noise, increased soft-tissue and iodine contrast, lower radiation dose, and inherent spectral imaging. This article comments on recent literature in neuroradiology covering the vessels, pituitary adenoma, temporal bone, and myelography while addressing certain issues and outlining future directions.
Keywords: computed tomography; myelography; photon counting detector CT.
