Prediction of left lobe hypertrophy with voxel-based dosimetry using integrated Y-90 PET/MRI after radioembolization of liver tumors with Y-90 microspheres.

Purpose: The aim of this study was to investigate the relationship between voxel-based dosimetric variables derived from Y-90 PET/MRI and hypertrophy observed in the left lobe after radioembolization and to investigate if there is any difference in hypertrophy induced by glass versus resin microspheres.

Methods: Voxel-based dosimetry-derived variables and their relationship with the change of the standardized future liver remnant (ΔFLR) was investigated with linear regression models. To compare and evaluate the discriminatory power of the dosimetric variables, ROC analyses were utilized.

Voxel-based dosimetry with integrated Y-90 PET/MRI and prediction of response of primary and metastatic liver tumors to radioembolization with Y-90 glass microspheres.

Purpose: In this study, we aimed to evaluate the response of the primary and metastatic liver tumors to radioembolization with Y glass microspheres and investigate its correlations with dosimetric variables calculated with Y PET/MRI.

Methods: In this ambispective study, 44 patients treated with Y glass microspheres and imaged with Y PET/MRI were included for analysis. Dosimetric analysis was performed for every perfused lesion using dose-volume histograms.

Clinical value of fluorine-18-fluorodeoxyglucose PET/MRI for liver metastasis in colorectal cancer: a prospective study.

Purpose: To evaluate the diagnostic performance of liver 18F-FDG PET/MRI in addition to whole-body PET/CT and to compare it with MRI in the detection and clinical management of liver metastasis in patients with colorectal cancer (CRC).

Material And Methods: Seventy-eight patients with CRC who underwent whole-body 18F-FDG PET/CT followed by liver PET/MRI were prospectively included. Histopathological confirmation and/or at least 3 months of clinical follow-up after PET/MRI were accepted as gold standard.

The Role of F-FLT PET/CT in Assessing Early Response to Transarterial Radioembolization and Chemoembolization in Patients with Primary and Metastatic Liver Tumors.

Objectives: Metastases and primary malignancies are common in the liver. Local ablative applications such as transarterial chemoembolization (TACE), and transarterial radioembolization (TARE) provide minimally invasive and safe treatment in unresectable liver tumors. Early detection of response to treatment prevents unnecessary toxicity and cost in non-responder patients and provides an earlier use of other options that may be effective.

Evaluation of the relationship between muscle mass and serum myostatin levels in chronic hemodialysis patients.

The loss of muscle mass and cachexia is commonly seen in hemodialysis (HD) patients and contribute to morbidity and mortality. The exact mechanism of this fact is multifactorial and still unclear. Myostatin, a transforming growth factor-ß family ligand, is released from the skeletal and heart muscle and may be responsible for muscle degradation and atrophy.

Effect of the application of prophylactic central compartment lymph node dissectionon radioiodine ablation doses in patients with papillary thyroid carcinoma.

Background/aim: The aim of this study was to document the effect of the application of prophylactic central compartment dissection on radioiodine ablation activities for papillary thyroid carcinoma.

Materials And Methods: This retrospective study included 452 (383 females, 69 males; mean age = 46.69 years, min-max: 13-71) patients who received ablative radioiodine activity between April 2010 and December 2014.

The Role of 18F-FDG PET/CT in the Primary Staging of Gastric Cancer.

Objective: The aim of this study is to explore the role of 18F-FDG PET/CT in the primary staging of gastric cancer in the comparison of ceCT as routine staging method and evaluate influencing parameters of 18F-FDG uptake.

Methods: Thirty-one patients (mean age: 58.9±12.

The role of 18F-FDG PET/CT in detecting colorectal cancer recurrence in patients with elevated CEA levels.

Introduction: In this study we aimed to define the success of fluorine-18 (18F) fluorodeoxyglucose (FDG) PET/computed tomography (PET/CT) in detecting recurrent disease in our patient group with colorectal cancer (CRC) and elevated carcinoembryonic antigen (CEA) levels.

Material And Method: Patients who had a previous diagnosis of CRC were searched retrospectively in our PET center database. Seventy-six 18F-FDG PET/CT studies between October 2006 and December 2010 of 69 patients (25 women, 44 men; mean age: 61.
