The radionuclide bone scan is the cornerstone of skeletal nuclear medicine imaging. Bone scintigraphy a highly sensitive diagnostic imaging technique that uses radiotracer to evaluate distribution active formation in skeleton related malignant and benign disease, as well physiological processes. European Association Nuclear Medicine (EANM) has written approved these guidelines promote use procedures high quality. present offer assistance practitioners optimizing procedure interpreting...
Abstract Purpose Improved logistics and availability led to a rapid increase in the use of [ 18 F]-PSMA-1007 for prostate cancer PET imaging. Initial data suggests increased uptake benign lesions compared 68 Ga]-PSMA-11, clinical observations found unspecific bone (UBU). We therefore investigate frequency characteristics UBU PET. Methods retrospectively analyzed scans from four centers presence UBU, defined as focal mild-to-moderate (SUV max < 10.0) not obviously related or malignant...
Patients with pancreatic cancer continue to have a poor prognosis, 5-y survival rate of less than 5%. Surgery is the only treatment that offers potential cure. Determining resectability principal goal staging in patients. Our objective was evaluate value combined contrast-enhanced <sup>18</sup>F-FDG PET/CT assessing and compare enhanced performance PET alone unenhanced PET/CT. <b>Methods:</b> Fifty patients (25 women 25 men; mean age, 64.3 y; range, 39–84 y) biopsy-proven adenocarcinoma...
Purpose: To prospectively determine the accuracy of positron emission tomography (PET)/computed (CT) with added CT morphologic information for depiction metastases in patients high-risk melanoma and negative findings at PET, by using histologic or additional imaging and/or follow-up as reference standard. Materials Methods: Institutional review board approval was obtained. Informed consent obtained from patients. One hundred twenty-four consecutive (65 female, 59 male; mean age, 54.4 years;...
To prospectively evaluate the accuracy of ultrasonography (US) in depicting fatty atrophy supraspinatus (SSP) and infraspinatus (ISP) muscles, with magnetic resonance (MR) imaging as reference standard.Institutional review board approval informed consent were obtained. SSP ISP muscles 65 consecutive patients (27 women, 38 men; mean age, 53.1 years; range, 28-83 years) possible rotator cuff tears evaluated US two planes. Visibility muscle contour, pennate pattern, central tendon, echogenicity...
The purpose of this study was to evaluate the diagnostic performance planar 99mTc methylene diphosphonate bone scintigraphy compared with SPECT and fused CT in patients focal lesions axial skeleton.Thirty-seven 42 skeleton were included prospective study. All underwent scintigraphy, through lesions, SPECT-guided CT. images then digitally. three types evaluated separately from one another by two experienced reviewers working consensus. Visibility performance, certainty diagnosis evaluated....
Abstract Background. This study assesses the additional value of 18 F‐fluoro‐2‐deoxy‐ D ‐glucose positron emission tomography/CT ( F‐FDG‐PET/CT) with respect to synchronous primaries in patients undergoing panendoscopy for staging head and neck squamous cell carcinoma. Methods. In all, 311 underwent both modalities. Cytology, histology, and/or clinical/imaging follow‐up served as reference standard. Results. The prevalence second primary tumors detected by was 4.5%, compared 6.1%...
Abstract. Aim. Prevalence, optimal diagnostic approach and consequences of clinically unsuspected osteomyelitis in diabetic foot ulcers are unclear. Early diagnosis this infection may be crucial to ensure correct management. Methods. We conducted a prospective study 20 patients with chronic ulcer (>8 weeks) without antibiotic pretreatment clinical signs for assess the prevalence compare value magnetic resonance imaging (MRI), 18 F‐fluorodeoxyglucose positron emission tomography ( F‐FDG...
To retrospectively determine the sensitivity and specificity of co-registered fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed (CT) in patients with Hodgkin lymphoma after first-line therapy, use clinical follow-up or biopsy results as reference standard.Informed consent was obtained for imaging included to patient data research purposes. Institutional review board approval obtained. Between May 2001 July 2005, all (n=66) at authors' institution proved therapy...
Abstract Background. Cystic lymph node metastasis (CLNM) is commonly found in human papillomavirus (HPV)‐associated tonsillar squamous cell carcinoma (SCC). The aim of this study was to compare the accuracy detecting cystic from SCC between contrast‐enhanced CT, 18 F‐ fluorodeoxyglucose‐positron emission tomography (FDG‐PET), non‐enhanced F‐FDG‐PET/CT, and F‐FDG‐PET/CT. Methods. Thirty‐four patients with a undergoing pretreatment F‐FDG‐PET/CT followed by neck dissection as standard reference...
Abstract Background The aim of this study was to compare imaging modalities for staging the neck in a prospective cohort patients evaluated by CT, ultrasound with fine‐needle aspiration cytology (FNAC), and [ 18 F]fluoro‐2‐deoxy‐ D ‐glucose (FDG) positron emission tomography (PET)/CT histologic evaluation dissection as standard reference. Methods In all, 76 consecutive were prospectively enrolled. Results Ultrasound‐guided FNAC showed highest level agreement histology exact N classification....
