WebbHigh-resolution computed tomography ( HRCT) is a type of computed tomography (CT) with specific techniques to enhance image resolution. It is used in the diagnosis of various health problems, though most commonly for lung disease, by assessing the lung parenchyma. [1] WebbOne advantage of 4D CT over slow CT, mentioned above, is that the image in each respiratory bin is quite sharp. There is, however, typically more noise in 4D CT images versus a standard helical scan because vendor protocols typically reduce the mA in 4D CT scans in order to limit the dose.
