OBJECTIVES Positron emission tomography using 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ((18) F-FDG) is considered to be the most beneficial imaging method for staging patients with non-Hodgkin's lymphoma (NHL). The intensity of (18) F-FDG accumulation may be determined by calculating the so-called standardised uptake value (SUV). The study aimed at(More)
Indications for elective neck dissection (ELND) and its extent in N0-staged patients with parotid gland carcinoma are inconsistent. Therefore, a pilot study was performed to test the feasibility and efficacy of radioguided sentinel lymph node biopsy (SLNB) in these tumors. A total of 6 patients underwent lymphoscintigraphy, SLNB, and level II-IV ELND. In 2(More)
PURPOSE This study used radionuclide angiography to evaluate semiquantitatively the hepatic arterial blood flow changes associated with cirrhosis. METHODS The parameters of net arterial hepatic perfusion were estimated by analysis of first-pass flow studies in 11 control participants and in 15 patients with cirrhosis (Child-Pugh classification B-C).(More)
PURPOSE The authors wanted to identify those patients assessed by exercise SPECT in whom the quantification of lung Tl-201 uptake helps to evaluate disease prognosis. METHODS One hundred forty-nine patients (114 men, 35 women; 74 after myocardial infarction [MI]; mean age, 54 +/- 9 years) underwent exercise Tl-201 SPECT. The SPECT patterns were divided(More)
OBJECTIVE The aim of this study was to evaluate the feasibility of pre-operative lymphoscintigraphy and radio-guided surgery in endometrial cancer patients after intramyometrial administration of labelled colloid. DESIGN Prospective study. SETTING Department of Obstetrics and Gynaecology of the Palacký University Medical School and University Hospital,(More)
Dear Sir, We read with great interest the recent article by Glaudemans et al. [1]. The authors sought to identify the most accurate white blood cell (WBC) scintigraphy acquisition and interpretation protocols in patients with musculoskeletal infections. They recommend using optimal acquisition times (at 3 – 4 h and at 20 – 24 h after injection) and(More)
INTRODUCTION Breast cancer treatment currently represents one of the biggest challenges in clinical oncology. The gold standard for axillary lymph node management is to perform sentinel node biopsy to avoid axillary dissection and its sequelae. The detection of radiocolloid flow outside the axillary nodes is a diagnostic and therapeutic challenge. METHODS(More)
BACKGROUND The European procedural guidelines for cardiac gated SPECT imaging demonstrate considerable variability in recommended administered radiopharmaceutical activity and imaging protocols. This study compared stress-only and stress-rest protocols to evaluate the safety of stress-only imaging, and to identify characteristics of patients who need full(More)
Parathyroid cysts are uncommon lesions that do not have a specific sonographic appearance. We report a rare case of a functionally active cystic parathyroid adenoma as a cause of primary hyperparathyroidism and discuss the difficulties associated with the diagnosis. In this case, the association with a multinodular goiter made preoperative differentiation(More)
PURPOSE The aim of this work was to introduce a new algorithm for image reconstruction in bone SPECT and to compare its performances with a commercially available standard OSEM and resolution recovery (RR) reconstruction. MATERIALS AND METHODS The algorithm was built applying the Lucy-Richardson deconvolution adn logarithmic image processing to the(More)
