[Imaging techniques in rheumatology : PET in rheumatology.]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Positron emission tomography (PET) using F-18-fluoro-deoxyglucose (FDG) is suitable for many indications in oncology and can also be used in rheumatology to search for inflammatory foci and benign lesions with increased glucose metabolism in, for example soft tissue and joints (arthritis, vasculitis etc.) and fever of unknown origin. Usually a whole-body scanning technique is used for data acquisition in the search for foci of unknown localization or for the characterization of glucose metabolism of one or more known lesions - also for observation of the effect of, for example pharmacotherapy. Patients are admitted und...

Assessment of Pedicle Screws Following Dorsal Instrumentation of the Spine: a Comparison of Conventional Radiographs with Multidetector CT.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: CR evaluation of pedicle screws following dorsal instrumentation of the spine demonstrated an OA </= 90 % for relevant medial and lateral perforation and for incorrect screw length compared to CT. Thus, reliable evaluation of pedicle screws based solely on CR does not seem feasible. PMID: 19862653 [PubMed - as supplied by publisher] (Source: Nuklearmedizin)

How to choose PET-CT or CT in the diagnosis of lung cancer.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
How to use CT and PET-CT rationally to raise diagnosis, staging and prognostic assessment of lung cancer to a higher level at the best cost-effect ratio is a subject that Chinese clinicians and radiologists should face conscientiously. We review the rational application of CT and PET-CT in four aspects of lung cancer, including screening and detection, morphologic evaluation, haemodynamic or metabolic feature evaluation, and follow-up, staging and prognostic evaluation. As PET-CT is only available in class III-A hospitals today, CT is the most popular equipment in China. PET-CT is more valuable only in cases where CT p...

THE RBE OF 3.4 MeV {alpha}-PARTICLES AND 0.565 MeV NEUTRONS RELATIVE TO 60Co {gamma}-RAYS FOR NEOPLASTIC TRANSFORMATION OF HUMAN HYBRID CELLS AND THE IMPACT OF CULTURE CONDITIONS.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The neoplastic transformation of human hybrid CGL1 cells is affected by perturbations from external influences such as serum batch and concentration, the number of medium changes during the 21-day expression period and cell seeding density. Nevertheless, for doses up to 1.5 Gy, published transformation frequencies for low linear energy transfer (LET) radiations (gamma-rays, MeV electrons or photons) are in good agreement, whereas for higher doses larger variations are reported. The (60)Co gamma-ray data here for doses up to 1.5 Gy, using a low-yield serum batch and only one medium change, are in agreement with publishe...

Comparing time activity curves using the Akaike information criterion.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The comparison of curves is a common task in many fields of science. Simply comparing the sums of squares or R(2) is not sufficient, and frequently used tests have many disadvantages. The basic idea of the presented method is turning the problem of comparing curves into a problem of model selection using the corrected Akaike Information Criterion. Here, this straightforward approach is applied for comparing curves using the example of (111)In- and (90)Y-labelled anti-CD66 antibody serum time activity data. As a result it is shown that for the investigated (111)In- and (90)Y-labelled anti-CD66 antibodies, the biokinetic...

[Diagnosis of fever of unknown origin (FUO) - positron emission tomography/computed tomography (PET-CT)]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Nuclear medicine imaging is now well accepted for the localization of septic foci. But in patients the results of infection scintigraphy, radiology and ultrasound remain unsatisfactory in the diagnosis of fever of unknown origin (FUO). In contrast to septic infections, patients with FUO - mostly in elderly patients - tend to have such conditions as occult tumours, atypical pneumonia, hematoblastosis, malignant lymphomas. (18)F(Fluor-18)-Fluordeoxyglucose-PET ((18)F-FDG PET) has made it possible to localize symptomatically occult changes with a high diagnostic accuracy and to achieve differentiation between benign and m...

Image-guided interstitial high-dose-rate brachytherapy in hepatocellular carcinoma.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
New interventional options especially for patients with HCC and BCLC scores B and C give rise to disputes about the optimal therapeutic management. CT-guided brachytherapy complements established interventional techniques like RFA and TACE since it may also be used successfully in tumors much greater than 5 cm in diameter. In addition, unlike thermal ablation, the brachytherapy technique may be applied in tumors located nearby risk structures such as liver hilum or gallbladder and it is independent of cooling effects such as through large blood vessels or strong tumor perfusion. Depending on tumor size, geometry and vi...

The potential value of a pictorial atlas for aid in the visual diagnosis of 123I FP-CIT SPECT scans.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Diagnostic accuracy was significantly higher and interobserver variability significantly lower if observers had access to the atlas compared to when they had not. Hence, having a pictorial atlas available may facilitate the visual assessment of <sup>123</sup>I FP-CIT SPECT scans. PMID: 19488462 [PubMed - as supplied by publisher] (Source: Nuklearmedizin)

MIBI scintigraphy in hypofunctioning thyroid nodules - Can it predict the dignity of the lesion?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Even in areas of former or mild iodine deficiency MIBI forms a basis for choosing between wait-and-see and surgical strategies if FNAB is unfeasible or not representative. However, even for pathological MIBI results, the prevalence of malignancy is not very high. PMID: 19488463 [PubMed - as supplied by publisher] (Source: Nuklearmedizin)
