Responsiveness of FDG PET/CT to treatment of patients with active chronic sarcoidosis.

Purpose: This study aimed to compare baseline to follow-up 18F-FDG PET/CT findings after treatment for active chronic sarcoidosis and to correlate changes on 18F-FDG PET/CT with changes in clinical status.

Patients And Methods: The sample included 66 patients with chronic sarcoidosis and evidence of active inflammation on baseline F-FDG PET/CT for which they received therapy. Of these 66 patients, 30 returned for the follow-up 18F-FDG PET/CT after 12 (5) months to evaluate response to treatment.

The utility of 18F-FDG PET/CT for diagnosis and adjustment of therapy in patients with active chronic sarcoidosis.

Unlabelled: The purpose of this study was to assess the utility of (18)F-FDG PET/CT for detection of inflammation in granulomatous sites and management of patients with chronic sarcoidosis. The 3 specific aims were to assess differences between (18)F-FDG PET/CT and multidetector CT (MDCT) findings, to compare (18)F-FDG PET/CT results with serum levels of angiotensin-converting enzyme (ACE), and to determine whether (18)F-FDG PET/CT findings are associated with the decision to change therapy.

Methods: We studied 90 sarcoidosis patients (mean age ± SD, 47 ± 12 y; 32 men and 58 women) with persistent symptoms who were referred for (18)F-FDG PET/CT evaluation to assess the extent of inflammation.

The utility of two somatostatin analog radiopharmaceuticals in assessment of radiologically indeterminate pulmonary lesions.

Purpose: The aim of our study was to assess diagnostic accuracy of Tc-99m depreotide and Tc-99m-EDDA/HYNIC-TOC scintigraphy for evaluation of pulmonary lesions that appeared ambiguous on computed tomography (CT).

Material And Methods: Forty-nine consecutive patients (37 men and 12 women; mean age, 60 ± 11 years) with 60 pulmonary lesions on chest radiography and CT were referred for nuclear imaging. They were prospectively allocated to undergo whole-body scintigraphy (WBS) and single photon emission computed tomography (SPECT) using either Tc-99m depreotide (26 patients, group 1) or Tc-99m-EDDA/HYNIC-TOC imaging (23 patients, group 2).

Usefulness of gated SPECT myocardial imaging in evaluation of patients with inferior myocardial infarction.

Objective: Gated single photon emission computed tomography (gated SPECT) myocardial imaging gives useful information about the extent and severity of perfusion abnormalities (PA) and global left ventricular (LV) function in patients with coronary artery disease. The aim of this study was to evaluate by gated SPECT myocardial imaging differences in perfusion scores and LV function between stress and rest in patients with mild left ventricular dysfunction and/or normal function and previous inferior myocardial infarction (IMI) and to detect myocardial stunning.

Materials And Methods: The study included 77 patients (age 53 ± 8.

Metabolic syndrome impacts the right ventricle: true or false?

Background: The impact of metabolic syndrome (MS) on the right ventricle (RV) is not clarified. The aim of this study was to evaluate the influence of MS and its components on RV structure and function.

Methods: The study included 265 subjects with MS and 118 controls adjusted by age.

Preliminary experience with 18f-fluoro-deoxy-glucose positron emission tomography/computed tomography in pediatric oncology patients.

The aim of this study was to present preliminary experience with FDG PET/CT in pediatric oncology patients in National PET Center, Clinical Center of Serbia and to asses its impact on management of malignancies in children. 33 FDG PET/CT scans were performed on 30 pediatric patients. PET/CT imaging was performed for staging the disease, assessing therapy efficacy and diagnosing recurrent or metastatic disease.
