Gated cardiac imaging using a continuously rotating CT scanner: clinical evaluation of 91 patients.
To produce electrocardiographically (ECG)-gated computed tomographic (CT) images of the heart, a post-data-acquisition ECG correlation technique was used in which data for missing angular projections are derived from the original scan data to complete 360 angular projections. Improved image quality and clinical usefulness were demonstrated compared with routine nongated CT and two-dimensional echocardiography. Gated CT was better than nongated CT in 26 of 41 positive and three of five negative cases of suspected myocardial infarction, four of 10 positive and one of 12 negative cases of suspected left atrial mass, three of 10 cases with pericardial fluid collection, and three other cases. Compared with echocardiography, CT was of additional value in eight of 10 cases of myocardial infarction, five of nine positive and one of 10 negative cases of suspected left atrial mass, four of 10 positive and one of three negative cases of suspected pericardial fluid collection, and two other cases. The equipment required for CT gating is of low cost, but the examination time is lengthy and less conveniently performed than echocardiography. However, when echocardiography is indecisive or suspected to be falsely negative, gated CT imaging of the heart is recommended.

[In vivo X-ray fluorescent analysis of iodine concentration in the thyroid (author's transl)].
A simple apparatus was made for the X-ray fluorescent analysis of iodine concentration of the thyroid. The apparatus consists of 241Am gamma-ray source of 300mCi and pure Ge detector of 50mm2X5mm. Diverging collimator was designed to achieve a full view of the thyroid. The detectable concentration was 0.2mg iodine/g tissue assuming the coefficient of variance of 30% and the counting time of 5 minutes. Measurement was performed for autopsied 10 thyroids and the results were in good correlation with those by neutron activation analysis (r=0.93). Iodine concentration ranged 0.3-1.2mg/g (mean 0.6mg/g) and compared well with the data in literatures. This technique is useful for the in vivo measurement of thyroidal iodine content in patients.
