[Determination of the value of conventional and computer-assisted tomography in examining the thoracic organs].

We compared the results of CT and conventional tomography examinations of the thorax of 137 patients with each other and with the final results. In the diagnosis of bronchial carcinomas we found no significant differences between the two methods. In all other investigated items CT proved to be superior to conventional tomography, especially of the evaluation of mediastinum (90% vs. 35%). We conclude that CT is the method of choice in the staging of intrathoracic tumours and especially in the evaluation of hilar and mediastinal masses and there is no need for conventional tomography in these cases.

Cranial CT artifacts and gantry angulation.

Computed tomographic investigation of the brain is frequently accomplished by scanning parallel to the canthomeatal line. In these scans, evaluation of the brain stem and neighboring structures is often compromised by streak artifacts from bone-induced beam hardening. These artifacts may be reduced by introducing a change in gantry angulation. Results from a phantom study as well as from a clinical trial offer evidence that may be helpful in assessing different scanning planes. An inclination of 5 degrees below Reid baseline is suggested to minimize the interpetrous artifact. Variations in slice thickness and exposure parameters do not appear to affect significantly this typical posterior fossa artifact.
