Relationship between Lymph Node Metastasis and a Low 18F-FDG PET/CT Axillary SUVmax Value in Breast Cancer.

Objective:  To evaluate breast cancer patients with low F18-fluorodeoxy-glucose positron emission tomography/computed tomography scan (FPET) of axilla standardised maximum uptake value (SUVmax) along with their histopathological findings regarding axillary lymph node metastasis (LNM).

Study Design: A descriptive study. Place and Duration of the Study: Adana City Education and Research Hospital, Turkey, from January 2015 to October 2018.

The Value of 18F-FDG PET/CT in Detecting Bone Marrow Involvement in Childhood Cancers.

Background: The aim of this study was to assess the utility of F-fluoro-2-deoxy-D-glucose (F-FDG) positron emission tomography/computed tomography (PET/CT) in assessing bone marrow involvement (BMI) compared with bone marrow biopsy (BMB) in the initial staging of pediatric patients with non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), Ewing sarcoma (ES), and neuroblastoma (NB).

Procedure: A total of 94 patients (57 boys, 37 girls, median age 7 y, range 1 to 18 y) with newly diagnosed NHL, HL, ES, and NB between July 2014 and December 2017, who underwent BMB and F-FDG PET/CT before chemotherapy were included in this study. There were 36 patients with NHL, 27 HL, 16 ES, and 15 NB.

The Diagnostic Efficiency of 99mTc-EDDA/HYNIC-Octreotate SPECT-CT in Comparison with 111In-Pentetrotide in the Detection of Neuroendocrine Tumours.

Objective: The aim of this study was to assess the diagnostic efficiency of (99m)Tc-EDDA/HYNIC-Octreotate in comparison with (111)Inpentetrotide scintigraphy in the detection of neuroendocrine tumors. This study also evaluates the impact of SPECT-CT hybrid imaging on somatostatin receptor scintigraphy (SRS) interpretation and clinical management of these tumors.

Methods: Fourteen patients were included in the study.
