[Comparison of the value of general and oblique images and whole lung tomography in a high kilovoltage technic in the detection of pulmonary coin lesions].

The ranking of high kvp pa. and lateral chest x-ray, left and right oblique films and whole lung tomography in the detection of pulmonary coin-shaped lesions is compared. Out of a total number of 327 coin lesions in 115 patients detected by high kvp whole lung tomography, only 52% were found on pa and lateral chest films. Additional oblique films improved the score to 64%. Oblique films proved to be especially helpful in detecting pleural lesions. Although CT has a higher sensitivity in detecting nodules (with decreasing specificity) whole lung tomography will continue to play an important role in the management of tumour patients.
