Clinical application of computed tomography to thyroid disease.

CT examinations were carried out in 62 patients with various thyroid disorders, 42 patients with thyroid nodules, 12 with diffuse abnormality and 8 of others. Evaluation was made whether CT could provide more information compared with other techniques. Cystic thyroid nodules could be differentiated from solid nodules with a reasonably high degree of accuracy. Uncalcified thyroid carcinoma was noticed as an ill-defined nodule with irregular wall, grossly the same in density with the muscle in plain CT, and not opacified by contrast material. CT has the ability to define the nature of the thyroid nodules better than other nontraumatic diagnostic modalities.

Various manifestations of stratification phenomenon during intravenous cholangiography.

The authors classify various types of stratification phenomenon during intravenous cholangiography. The stage of gallbladder opacification in the recumbent position has been classified as (I) mottled, (II) dendritic, (III) ring-like, and (IV) homogeneous. 'Dendritic' type of stratification phenomenon has never been reported in the literature to our knowledge. At 20 min following infusion of contrast material homogeneous opacification of the gallbladder was noticed in only 14% of patients. The others fell into types I, II or III of stratification phenomenon. In contrast, 87% of the opacified gallbladders were homogeneous on the after fatty meal film. It is therefore mandatory for diagnosis that either a 24 h film or a fatty meal film be taken to avoid the stratification phenomenon.
