A comparative study of contrast dacryocystogram and nuclear dacryocystogram.

A comparative study was run between conventional radiographic contrast dacryocystogram and radioisotope scan of the lacrimal drainage apparatus (henceforth called "nuclear dacryocystogram"). A total of 20 contrast dacryocystograms (DCG), 22 irrigations, and 42 nuclear dacryocystograms (DCG) were performed in 21 patients having symptoms of obstruction in the lacrimal drainage system. The study revealed that there was a good correlation between these two diagnostic techniques and nuclear DCG was, perhaps, superior to contrast DCG.

Paranasal sinus radiology, part 1B: the frontal sinuses.

Alteration in the appearance of the mucosa, fluid accumulations, and change in the shape and texture of the sinus wall form the basis of the radiologic information that aids in the diagnosis of frontal sinus disease. Inflammatory disease of the frontal sinuses was discussed in Part 1A of this article; other disease processes of the frontal sinuses as they appear in the various roentgenographic modalities are described and illustrated here.

Paranasal sinus radiology, Part 2A: Ethmoidal sinuses.

The clinician must have a high level of suspicion in order to detect ethmoidal sinus disease. Survey plain film radiographic examination may provide information about gross changes in ethmoidal sinus transparency and the sinus walls. Conventional tomographic study will often aid evaluation of the ethmoidal sinus walls which may be obscured by overlying structures on plain films. Computerized tomography adds a new dimension to ethmoidal sinus study. By revealing not only bone changes but soft-tissue abnormality as well, more complete understanding of the disease process is gained. Computerized tomography is particularly useful in evaluating orbital structural change due to ethmoidal sinus abnormality
