Primary systemic vasculitis is a group of heterogeneous disorders, characterized by inflammation of blood vessels causing end organ damage from ischemia, aneurysm formation or dissection. Delay in the early diagnosis owing to non-specific symptoms, lack of definitive serological tests, limited availability of biopsy and standard imaging tests pose significant challenge in the management of these diseases. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) scanning is being increasin...

A 52-year-old woman presented with apparent carcinoid syndrome. Gallium 68 (Ga)-DOTATOC positron emission tomography (PET)/computed tomography (CT) found a 2.5-cm somatostatin receptor (SR)positive nodule in the left thyroid lobe. Basal serum calcitonin was 5184 ng/L, TSH was 0.63 mU/L, and free T4 was 16.98 pmol/L, so medullary thyroid cancer was suspected. Ultrasonography (Figure 1, A and B), F-fluorodeoxyglucose (FDG) PET/CT, and iodine 124 (I) PET/ CT, performed to allocate thyroid nodules t...

In der Diagnostik von rheumatologischen Erkrankungen im Bereich der peripheren Gelenke und des Achsenskelettes stellt das Rontgenbild weiterhin die primare bildgebende Diagnostik aufgrund der ubiquitaren Verfugbarkeit als auch der standardisierten Durchfuhrbarkeit dar. Die Rontgendiagnostik wird insbesondere zur Beurteilung der Manifestation einer rheumatologischen Erkrankung am Achsenskelett und an den peripheren Gelenken, zur Verifizierung des radiologischen Schweregrades und zur Quantifizieru...
Abstract The purpose of this study is to investigate I-124 positron emission tomography (PET)/ultrasound (US) fusion imaging for function assessment of thyroid nodules. In 70 patients, 201 lesions were examined with conventional diagnostics (CD) (thyroid US, laboratory findings and Tc-99m pertechnetate scintigraphy), Tc-99m pertechnetate single photon emission computed tomography (SPECT) and I-124 PET/computed tomography (CT). Subsequently, US fusion imaging (SPECT/US and PET/US) was performed b...
