The paper reviews current scientific publishing practice in the journal Nuklearmedizin. ⋯ The number of authors per paper documents the tendency to team work with a major participation of other specialties; university hospitals and research centers are represented more often. There is a predominance of clinical research with a high average number of patients per study. The percentage of first female authors are proportionate to their percentage membership in the learned societies. The relatively high percentage of papers in English raises the potential to increase the scientific response to publication of the content.

Pulmonary thromboembolism: a retrospective study on the examination of 991 patients by ventilation/perfusion SPECT using Technegas.
Conventional planar ventilation/perfusion (V/P)-imaging in those patients suspected of suffering from pulmonary thromboembolism (PTE) is of limited diagnostic value. It is the purpose of this retrospective study to determine whether the use of V/P-SPECT using Technegas might reduce the rate of those diagnostic uncertainties and might lead to better results. ⋯ We conclude that V/P imaging can be improved significantly by V/P SPECT using Technegas.

[The insufficiency fracture of the sacrum. An often unrecognized cause of low back pain: results of bone scanning in a major hospital].
The insufficiency fracture of the sacrum is often radiographically occult. Bone scintigraphy is a method of reference for the diagnosis; the results have been analysed retrospectively. ⋯ The insufficiency fracture of the sacrum as cause of lower back pain is not uncommon, especially in postmenopausal women with risk factors. Bone scintigraphy is not only an adequate procedure for the detection of often radiographically occult sacral fractures, but also an easy method to reveal the often concomitant fractures.

Comparative Study[Assessment of left ventricular function and volume by myocardial perfusion scintigraphy--comparison of two algorithms].
Left ventricular volume and function can be computed from gated SPECT myocardial perfusion imaging using Emory Cardiac Toolbox (ECT) or Gated SPECT Quantification (GS-Quant). The aim of this study was to compare both programs with respect to their practical application, stability and precision on heart-models as well as in clinical use. ⋯ GS-Quant and ECT are two reliable programs in estimating LVEF. Both seem to underestimate the cardiac volume. In practical application GS-Quant was faster and easier to use. ECT allows the user to define the contour of the ventricle and thus is less susceptible to artifacts.

Optimizing ventilation-perfusion lung scintigraphy: parting with planar imaging.
Of the study was to introduce and verify a ventilation-perfusion (V/Q) acquisition protocol that incorporates new developments in scintigraphy in order to allow for a more balanced comparison with other diagnostic procedures. ⋯ In conclusion this protocol provides high-resolution tomographic scans as well as high-quality planar images within a short acquisition time. Due to the significant increase in lesion detection, sensitivity, diagnostic accuracy, and anatomical localization of defects, it is a substantial improvement in the diagnosis of pulmonary embolism that will put V/Q scintigraphy on a par with other tomographic methods.
