With the use of the new needle structured storage phosphors in chest radiography, dose reduction of up to 50 % is possible without detracting from image quality or detail depiction. Especially in patients with multiple follow-up studies the overall dose can be decreased significantly.

Between 1963 and 1971, radioiodine (133I) treatment of a toxic thyroid adenoma was performed in 229 patients, in 70% the dosage being 30000 rd. In 188 patients the results were checked an average of 2 1/2 years later. Subjective improvement or freedom from symptoms was achieved in 76% (in 85% within 3-6 months), body weight increased, serum cholesterol level rose significantly, while pulse rate, pulse amplitude, PB127I and index of free thyroid hormones significantly fell. The 131I two-phase test was inconclusive. 72% of toxic adenomas were inactivated and 88% of patients with still active adenomas were improved or free from symptoms. Clinical improvement apparently preceded the scanning results. Corresponding to the index of free thyroid hormones, 94% were euthyroid, 0.6% hyperthroid, and 2.8% suspected of being hypothryoid. In combination with other findings, especially isotope scanning, 1.7% of patients were suspected of having T3 hyperthyroidism after treatment. A recurrence was observed in 2.1%. The success rate increased with rising radiation dose up to 30000 rd.

This data indicate that diminished BMD in terms of osteopenia or osteoporosis is a frequent finding in hip fractures of elderly females. A large majority of these elderly patients therefore should be treated according to recent guidelines for treatment of osteoporosis. Our data indicate that this entity is potentially underdiagnosed and should be considered by radiologists as well as traumatologists.

Vertebroplasty and kyphoplasty can be safely performed using only MSCT fluoroscopy guidance. The rate of major complications is very low. There was a high rate of small asymptomatic cement leakages which may have remained undetected with conventional fluoroscopy (CF). There was no statistically significant advantage for kyphoplasty with respect to cement leakage and the technical success rate.
