However, the overall efficacy of the third protocol was not significantly different as compared to two rhTSH injections. Under the aspect of the supply shortage of rhTSH the combined endogenous and exogenous TSH stimulation may be an attractive alternative for remnant ablation in differentiated thyroid cancer.

The early involvement and communication with the authorities avoids time-consuming and costly planning errors. It is much to be hoped that the new legal situation in Germany will not cause serious impairments in the realization of clinical trials in German nuclear medicine.

PET with (68)Ga-DOTATATE or (68)Ga-DOTATOC, both with a high affinity to the SSTR subtype 2, enables diagnosis of NET with a very high sensitivity and has a significant influence on the therapeutic management of patients with NET. In particular, therapy with (177)Lu-DOTATATE, which offers a considerably lower nephrotoxicity as compared to (90)Y-DOTATOC, has only few side effects and is usually well tolerated. Up to 46% of patients suffering from GE...

The most frequently used PET tracer in oncology, 2-[18F]fluoro-2-deoxyglucose (FDG), suffers from low specificity due to uptake in inflammatory cells. The proliferation marker, 3'-[18F]fluoro-3'-deoxy-L-thymidine (FLT), is less influenced by the inflammatory response following therapy but here disease- and drug-specific effects need to be considered. Since cancer therapy mainly intends to eliminate cancer cells, imaging of cell death offers a direct way to image therapy response.

Computed tomography (CT)-guided brachytherapy has been used to treat primary and metastatic liver cancers, including very large tumors >10 cm. Cooling effects by adjacent blood vessels are not a concern in brachytherapy, and the method may be used safely in tumors unsuitable for thermal ablation that are close to the liver hilum due to the relatively high radiation tolerance of bile duct.

AMACR is involved in the β-oxidation of the dietary branched-chain fatty acids and bile acid intermediates. It is highly expressed in prostate (more than 95 %), colon (92 %), and breast cancers (44 %) but not in the respective normal or hyperplastic tissues. Thus, targeting of AMACR could be a new strategy for molecular imaging and therapy of prostate and some other cancer...

Whereas there are no serum tumor markers in the first group, they are present in nonseminomatous tumors, and are also important prognostic factors. Overall, the prognosis for testicular cancers is good, which makes the choice of accurate treatment intensity between under- and overtreatment often difficult. Residual masses in advanced clinical stages occur frequently but are nonvital tissue. PET with F-18 FDG has no defined role in imaging of primary tumors where CT is the first-choice imaging modality. For assessing the success of chemotherapy in the presence of residual masses, especially in pure seminoma, F-18 FDG PET is an important tool. In nonseminomatous tumors, it is h...

A follow-up study did not show any suspicious lesion in this area, but pneumonia with 18F-FDG uptake in another region of the lung. 18F-FDG foci without pathological CT are a rare finding and have been associated with emboli. In the literature two main mechanisms underlying focal 18F-FDG uptake in pulmonary embolism are mentioned: an inflammatory reaction of a pre-existing vascular thrombus and an iatrogenic microembolism caused during injection. In our case the 18F-FDG accumulation was assessed as an iatrogenic pulmonary microembolism. PMID: 21498287 [PubMed - as supplied by publisher] (Source: Nuklearmedizin...

Patients with clinically positive axillary lymph nodes have a higher chance of unsuccessful lymphatic mapping by lymphoscintigraphy. Performing SLNB before NCTX in clinically node-negative patients may identify the subset of patients in whom axillary lymph node dissection can be omitted. Post NCTX axillary ultrasonography and 18F-FDG-PET/CT can not be suggested as valid axillary staging methods in case of a failed lymphatic mapping.

Since ES and PNET (primitive neuroectodermal tumours) may cause peripheral metastases some centers routinely recommend whole body PET acquisition from head to toe what may necessitate repositioning of the patient and thus extending examination time. It is not clear yet whether inclusion of lower leg adds to the diagnostic accuracy of PET scanning, especially in primary tumors of the trunk. PATIENTS, METHOD: 40 patients with ES and PNET of the trunk who were referred for surveillance after primary therapy with complete remission, were evaluated retrospectively: 27 men, 13 women; mean age at diagn...

From a historical point of view, (18)F-fluoride was one of the first osteotropic tracers which was replaced by (99m)Tc-labelled polyphosphonates. With the development of modern PET equipment the superior diagnostic performance of (18)F-fluoride PET for the detection and characterization of osseous lesions was proven in comparison to conventional bone scanning. Recently, its importance as a substitute of conventional skeletal scintigraphy increased in a time with limited availability of (99)Mo/(99m)Tc.

These complications can not a priori be considered as an indication of a too aggressive therapy. Based on the time of first diagnosis, early (acute) and late (chronic) radiation sequelae in normal tissues can be distinguished. Early reactions per definition occur within 90 days after onset of the radiation exposure. They are based on impairment of cell production in turnover tissues, which in face of ongoing cell loss results in hypoplasia and eventually a complete loss of functional cells. The latent time is largely independent of dose and is defined by tissue biology...

These lesions may lead to lethal chromosome aberrations, which are the main reason for cell inactivation. Double-strand breaks can be repaired by several different mechanisms. The regulation of these mechanisms appears be fairly different for normal and tumour cells. Among different cell lines capacity of double-strand break repair varies by only few percents and is known to be determined mostly by genetic factors. Knowledge about double-strand break repair mechanisms and their regulation is important for the optimal application of ionising irradiation in medicine.

In this context signaling pathways down-stream of epidermal growth factor receptor (EGFR), when abnormally activated, invoke cell survival mechanisms, which leads to resistance against radiation. In several reports it has been demonstrated that molecular targeting of EGFR signaling enhances the cytotoxic effects of radiotherapy. The radiosensitizing effects of EGFR antagonists correlate with a suppression of the ability of tumor cells to repair radiation-induced DNA double strand breaks (DNA-DSBs) through non-homologous end-joining repair pathway (NHEJ).

Normally fixed activities are administered without considering the individual biokinetics increasing the risk of under- or overdosing. In addition, it would be helpful to obtain additional data on dose-response relationships for further optimization of TRTs. Therefore, post-therapeutic dosimetry using quantitative imaging becomes more important. For an optimization of TRTs additional aspects such as the changing dose rate and radiobiological considerations need to be taken into account.

Integration of biological imaging using PET or MRI appears to be a promising concept to improve radiotherapy (Bio-IGRT). For this it is essential that biological imaging provides radiobiologically relevant information. Preclinical and clinical investigations into validation of PET tracers and MR methods in the context of curative radiotherapy and of concepts for biology-based escalation of radiation dose as well as other therapeutic interventions are an important task for further cancer research.

The introduction of IMRT(intensity modulated radiotherapy) allows specific boosting of tumor subvolumes that may harbour these radioresistant tumour cells. PET imaging of these subvolumes can be incorporated into treatment planning. However, at this moment microenvironmental changes visualized and quantified by means of PET-imaging need to be validated by high-resolution microscopic techniques.

The blood oxygenation level dependent (BOLD) imaging takes advantage of local field inhomogeneities and is based on a T2*-weighted sequence. BOLD is a non-invasive method allowing an estimation of the renal, particularly the medullary oxygenation, and an indirect measurement of blood flow without administration of contrast agents. Thus, effects of different drugs on the kidney and various renal diseases can be controlled and observed. This work will provide an overview of the studies carried out so far and identify ways how BOLD can be used in clinical studies. PMID: 20807689 [PubMed - indexed f...

Important goals of sentinel lymph node scintigraphy comprise reduction of the extent of surgery, lower postoperative morbidity and optimization of histopathological examination focussing on relevant lymph nodes. Sentinel lymph node scintigraphy itself does not diagnose tumorous lymph node involvement and is not indicated when lymph node metastases have been definitely diagnosed before sentinel lymph node scintigraphy...

Increasing radiotoxicity from intracellular 99mTc is explained most likely by increased dose deposition in cellular structures due to Auger- and conversion-electrons of low range and high local energy deposition.

However, additional reading of the non attenuation corrected PET is mandatory to assure best possible diagnostic confidence in PET. Since approximately half of all lesions found in PET/CT were not concordant, at least in a setting with a diagnostic CT the exams need to be reported by both a nuclear medicine physician and a radiologist in consensus.

This provides a sufficient diagnostic power and a shorter examination time, thus increasing patient comfort and scanner availability.

These guidelines are based on the recent guidelines of the Paediatric Committee of the European Association of Nuclear Medicine (EANM) (57) and have been translated and adapted to the current conditions in Germany. The adaptation of CT-parameters using PET/CT in children is covered in a more detailed way than in the EANM guideline taking...

However, there are considerable shifts from HO and UH to PP. The well known potential of MPS considering risk stratification and functional analysis has not been tapped so far. Both gated SPECT and a quantitative perfusion analysis should be performed routinely in every patient.

All responders wish to expand on e-learning but many report the lack of administrative support to do so. These data could be regarded as a basis for discussions of inter-university teaching scenarios.

In line with prior reports on structural changes in vessels, increased calcified atherosclerotic plaque burden was strongly associated with the occurrence of common cardiovascular risk factors.

However, additional reading of the non attenuation corrected PET is mandatory to assure best possible diagnostic confidence in PET. Since approximately half of all lesions found in PET/CT were not concordant, at least in a setting with a diagnostic CT the exams need to be reported by both a nuclear medicine physician and a radiologist in consensus.
