The objective of this study was to evaluate the role (68)Ga-labeled [1, 4, 7, 10-tetraazacyclododecane-1, 10-tetraacetic acid]-1-NaI(3)-octreotide (DOTA-NOC) PET/CT in diagnosis and management gastroenteropancreatic neuroendocrine tumors (NETs).One hundred nine patients (median age, 50 years) with NETs underwent (68)Ga-DOTA-NOC PET/CT. performed after injection 132-222 MBq (4-6 mCi) (68)Ga-DOTA-NOC. Images were evaluated by two experienced nuclear medicine physicians both qualitatively as...
Objective The correct diagnosis of tumor thrombosis and its differentiation from benign thrombus can change patient management prevent unnecessary anticoagulation treatment. This study was aimed at evaluating the role fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) in thrombosis, thromboembolism. Methods We conducted a retrospective review FDG PET-CT scans patients who underwent for staging/restaging known malignancy had FDG-avid thrombosis. Maximum...
The purpose of this study was to evaluate the role (68)Ga-labeled DOTANOC PET/CT for baseline evaluation patients with head and neck paragangliomas (HNPs).The data 26 (mean age ± SD, 34.3 10.4 y; 50% men) known or suspected HNPs who underwent (68)Ga-DOTANOC staging were retrospectively analyzed. performed after intravenous injection 132-222 MBq (68)Ga-DOTANOC. images evaluated by 2 experienced nuclear medicine physicians in consensus, both qualitatively quantitatively. findings grouped as...
This study aimed to compare the diagnostic performance of Ga-DOTANOC PET/CT with F-FDG in patients gastroenteropancreatic neuroendocrine tumors (GEP-NETs).Data 51 definite histological diagnosis GEP-NET who underwent both Ga-DOTA-NOC PET-CT and within a span 15 days were selected for this retrospective analysis. Sensitivity, specificity, predictive values calculated PET-CT, results compared on patientwise regionwise analysis.Ga-DOTA-NOC is superior analysis (P < 0.0001). On analysis, only...
The aim of this study was to prospectively evaluate the role various quantitative and semiquantitative metabolic parameters derived from dynamic static baseline F-FDG PET/CT in prediction overall survival (OS) non-small cell lung cancer (NSCLC) patients who were planned undergo platinum-based chemotherapy.Sixty (51 male 9 female patients) with biopsy-proven NSCLC mean age 59.55 ± 10.06 years chemotherapy enrolled study. Each patient underwent a regional whole-body after injecting 0.21 mCi/kg...
To evaluate the incremental value of single-photon emission computed tomography-computed tomography (SPECT-CT) over planar scintigraphy and SPECT alone for equivocal bone lesions in patients with breast cancer to assess its impact on patient management.A total 102 115 underwent SPECT-CT selected volume. Images were evaluated separate sessions minimize recall bias. A scoring scale 1-5 was used, where 1 is definitely metastatic, 2 probably 3 indeterminate, 4 benign, 5 benign. With receiver...
To prospectively examine the roles of positron emission tomography (PET)/computed (CT) and conventional contrast material-enhanced CT at baseline, after two cycles chemotherapy, completion chemotherapy in pediatric patients with nonlymphoblastic non-Hodgkin lymphoma (NHL) who were treated similar standard treatment protocols.The institutional ethics committee approved study protocol, all enrolled written informed consent was obtained. Patients NHL between January 2008 March 2010. underwent...
Objective: To evaluate the role of 68Ga-DOTANOC (68Gallium-labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-octreotide) PET/CT for localization primary tumor in patients with carcinoma unknown neuroendocrine origin. Material and Methods: Twenty (median age, 55 years; male 10) histopathologically proven metastatic no on conventional imaging were included study. was done after injection 132–222 MBq (4–6 mCi) 68Ga-DOTANOC. Images evaluated by 2 experienced nuclear...
To assess the patient radiation dose during routine clinical single-photon emission computed tomography-computed tomography (SPECT-CT) and measure increase as compared with SPECT alone.Data pertaining to 357 consecutive patients who had undergone radioisotope imaging along SPECT-CT of a selected volume were retrospectively evaluated. Dose injected radiopharmaceutical (MBq) was noted, effective (mSv) calculated per International Commission on Radiological Protection (ICRP) guidelines. The...
The aim of the present study was to evaluate whether computed tomography based-attenuation correction (CT-AC) provides any advantage over non-attenuation-corrected (NAC) images for qualitative and quantitative analysis single photon emission (SPECT) myocardial perfusion imaging (MPI).We retrospectively evaluated data 171 patients who underwent stress rest MPI SPECT/CT as per standard protocol. Angiography done within ±3 months taken reference standard. Two readers independently CT-AC NAC...
Automated brain tumor segmentation of MR image is a very challenging task in medical point view. As the nature tumor, it can appear anywhere region with any size, shape, and contrast, that makes process more difficult. In order to handle such issues, present work proposes an automated method using rough-fuzzy C-means (RFCM) shape based topological properties. C-means, overlapping partition efficiently handled by fuzzy membership uncertainty datasets resolved lower upper bound rough set....
