Computed tomography in the evaluation of sella and parasella lesions: the value of sagittal and coronal reconstructions.
A method is described whereby contiguous, thin-section (3 mm) axial CT scans are obtained followed by computer manipulation of the data to reconstruct good quality images in sagittal and coronal planes. The application of this technique in the evaluation of sella and parasella abnormalities is discussed. In our experience, this has resulted in an increased sensitivity of CT scanning for the detection of abnormalities around the sella. In addition, it has been possible to more accurately define the true extrasella extension of pituitary tumors.
