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)
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)
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)
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)
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)
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)
Positron emission tomography (PET) using 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18F-FDG) combined with computed tomography (CT) represents a three-dimensional imaging method suitable for staging in patients with non-Hodgkin's lymphomas (NHLs). The aim of our prospective multicenter study was to assess the value of initial PET/CT as compared with CT and(More)
Our modification of a method for the absolute quantification of gallium-67 uptake in lungs with a scintillation camera and computer is described. The uptake of 67Ga in lungs, expressed in percentage of administered radioactivity, was determined by the transmission-emission method. We proved theoretically and experimentally that a 67Ga planar source could be(More)
BACKGROUND Internal mammary nodes visualized during sentinel node biopsy for breast cancer, remain an unresolved management issue. Further, both internal mammary node (IMN) radiotherapy and biopsy have attendant risks and hence should be used with caution. The purpose of this review is to highlight the available data and evidence. METHODS AND RESULTS A(More)
BACKGROUND The management of internal mammary nodes (IMNs) during multidisciplinary treatment of breast cancer has been debated for the last four decades without unequivocal conclusion. PATIENTS AND METHODS We retrospectively reviewed patients with breast cancer who underwent sentinel lymph node biopsy at our center from 2008 until 2012. IMN drainage was(More)
