The aim of the study was to assess the usefulness of Technetium-99m diethylene triamine pentaacetic acid (Tc-99m DTPA) diuretic scan to diagnose calyceal diverticulum (CD). From January 2000 to June 2014, children with evidence of renal cystic lesions of undetermined diagnosis on ultrasound were enrolled. Computed tomography urography (CTU) and Tc-99m DTPA diuretic scan were performed to charac...

BACKGROUND Sarcoidosis is a systemic and multiorgan disease with unknown etiopathogenesis. Granulomas that do not undergo necrosis and caseous degeneration are distinctive for this disease. Mostly it is connected with young adults, more frequently females than males, and changes are mainly situated in the lymph nodes of the pulmonary hilus and pulmonary parenchyma. Somatotropin release inhibiti...

Purpose: The aimof this article was to evaluate the use of a novel engineered anti-CD20 protein based on the 10 kDa human fibronectin type 3 domain (FN3) and subsequently compare with Cu-rituximab for positron emission tomography (PET) imaging of CD20. Experimental Design: The engineered FN3CD20 and FN3WT were produced in Escherichia coli cells at 2 to 5 mg/L, conjugated to DOTA, labeled with C...

UNLABELLED Absolute quantitation of myocardial blood flow (MBF) by PET is an established method of analyzing coronary artery disease (CAD) but subject to the various shortcomings of available radiotracers. Flurpiridaz F 18 is a novel PET radiotracer that exhibits properties of an ideal tracer. METHODS A new absolute perfusion quantitation method with flurpiridaz was developed, taking advantag...

PURPOSE The aim of this article was to evaluate the use of a novel engineered anti-CD20 protein based on the 10 kDa human fibronectin type 3 domain (FN3) and subsequently compare with (64)Cu-rituximab for positron emission tomography (PET) imaging of CD20. EXPERIMENTAL DESIGN The engineered FN3(CD20) and FN3(WT) were produced in Escherichia coli cells at 2 to 5 mg/L, conjugated to DOTA, label...

and posterior spot views of pelvis were obtained, which revealed the same finding (fig. 1). Horizontal images of computed tomography (CT) (fig. 2) showed a mass in the retrovesical region consistent with fecal impaction in rectum (posterior to the bladder). The zone of absent radiotracer activity in posterior projection images of the pelvis was attributed to attenuation of gamma rays by impacte...
