Abstract
Multiphasic multidetector computed tomography (CT) forms the mainstay for the characterization of renal masses whereas magnetic resonance imaging (MRI) acts as a problem-solving tool in some cases. However, a few of the renal masses remain indeterminate even after evaluation by conventional imaging methods. To overcome the deficiency in current imaging techniques, advanced imaging methods have been devised and are being tested. This review will cover the role of contrast-enhanced ultrasonography, shear wave elastography, dual-energy CT, perfusion CT, MR perfusion, diffusion-weighted MRI, blood oxygen level-dependent MRI, MR spectroscopy, positron emission tomography (PET)/prostate-specific membrane antigen-PET in the characterization of renal masses.
Core Tip: To overcome the deficiency in the existing imaging techniques for adequate characterization of renal masses, newer/advanced imaging methods have been devised and are being tested. This review will cover contrast-enhanced ultrasonography, shear wave elastography, dual-energy computed tomography (CT), perfusion CT, diffusion-weighted magnetic resonance imaging (MRI), MR perfusion, blood oxygen level-dependent MRI, MR spectroscopy, and positron emission tomography (PET)/prostate-specific membrane antigen-PET.
