We evaluated the reproducibility and predictive value of texture parameters and existing parameters of 18F-FDG PET/CT images in Stage I non-small-cell lung cancer (NSCLC) patients treated with stereotactic body radiotherapy (SBRT). Twenty-six patients with Stage I NSCLC (T1-2N0M0) were retrospectively analyzed. All of the patients underwent an 18F-FDG PET/CT scan before treatment and were treated with SBRT. Each tumor was delineated using PET Edge (MIM Software Inc., Cleveland, OH), and texture parameters were calculated using open-source code CGITA...

A 44-year-old woman with newly diagnosed gastric adenocarcinoma by gastroscopy underwent F-FDG PET/CT to evaluate possible metastasis. The images demonstrated intense activity in the region of uterine corpus, as well as greater gastric curvature. Physiologic uptake of endometrium was initially suspected, given the rarity with which extragenital cancers metastasize to the uterus. Ultimately, the endometrium proved to be mucinous adenocarcinoma of gastric origin based on its shared histological features and compatible immunostaining profile...

Angiosarcomas are highly malignant and rare tumors of vascular or lymphatic endothelial cell origin with a poor prognosis. Lymphangiosarcoma associated with chronic lymphedema is known as Stewart-Treves syndrome. Stewart-Treves syndrome is primarily described in patients with lymphedema of an upper extremity occurring after breast cancer surgery including radical axillary lymph node dissection and subsequent radiotherapy. It is rarely described in the presence of idiopathic chronic lymphedema of the lower extremities...

F-FDG PET/CT is a sensitive noninvasive imaging tool for assessment of recurrent disease in patients with carcinoma cervix. Its role in early detection of recurrences especially in asymptomatic patients has been demonstrated well in literature. Metastatic involvement of the pancreas in patients with adenocarcinoma of the cervix is a rare occurrence, reported only few times in literature, and is predominantly documented to be associated with uncommon histopathologies such as neuroendocrine and small cell carcinoma...

BACKGROUND: There is currently no conclusive scientific evidence available regarding the role of the [18F]FDG PET/CT for detecting pulmonary metastases from colorectal cancer (PMCRC) in patients operated on for colorectal liver metastases (CRLM). In the follow up of patients who underwent surgery for CRLM, we compare CT-scan and [18F]FDG PET/CT in patients with PMCRC. METHODS: We designed the study prospectively performing an [18F]FDG PET/CT on all patients operated on for CRLM where the CT-scan detected PMCRC during the follow up...

With nonsmall cell lung cancer (NSCLC), accurate mediastinal nodal staging is crucial to determine whether a patient is or is not a surgical candidate. Traditionally, computed tomography (CT) and fluorodeoxy-D-glucose (FDG) positron emission tomography (PET)/CT are the initial steps followed by tissue sampling through mediastinoscopy and/or thoracotomy, which are invasive procedures. There is controversy regarding the possibility of omission of the invasive diagnostic procedures and solely relying on noninvasive presurgical staging CT and FDG PET/CT results...

With the widespread use of 2-deoxy-2-((18)F) fluoro-D-glucose positron emission tomography-computed tomography (FDG PET/CT) in oncologic imaging, it has become increasingly important for physicians who interpret FDG PET/CT scans to confidently recognize the spectrum of incidentally encountered benign and malignant findings. The adrenal glands represent an interesting nexus of multiple rare and common benign intrinsic tumors as well as metastases from a variety of primary malignancies. Given the breadth of adrenal gland pathology, careful description of the FDG PET/CT appearance of these pathologies is of value to help reduce misinterpretation...

Fluorodeoxyglucose (FDG)-positron emission tomography-computed tomography (PET-CT) has been playing a pivotal role in tumor imaging for the past 20 years. Head and neck (HN) cancers are a good example that can illustrate such unique role of FDG imaging contributing to the patient's management. In this review article, we will describe the normal physiological distribution of FDG within HN structures focusing on its limitations and pitfalls. In addition, we will be also describing its role in the initial staging and restaging of the disease, particularly with regard to therapy response assessment...

BACKGROUND/OBJECTIVES: We evaluated the usefulness of positron emission tomography (PET)/contrast-enhanced computed tomography (CE-CT) in discriminating between malignant and benign intraductal papillary mucinous neoplasms (IPMNs). METHODS: PET/CE-CT imaging was conducted on 29 IPMN lesions, which subsequently underwent surgery. Preoperative findings on PET/CE-CT imaging were compared with the histological findings of the resected specimens to determine the diagnostic accuracy of PET/CE-CT imaging for evaluation of the differential diagnosis between benign and malignant IPMNs...

Tumour hypoxia can be detected by (18)F-fluoromisonidazole positron emission tomography (FMISO-PET). Few studies have assessed the relationships of new PET parameters, including hypoxic volume (HV), metabolic tumour volume (MTV), and total lesion glycolysis (TLG), with 5-year survival of patients treated surgically for oral squamous cell carcinoma (OSCC). This study evaluated the relationships between these PET parameters and 5-year survival in OSCC patients. Twenty-three patients (age 42-84 years; 15 male, eight female) with OSCC underwent FMISO- and (18)F-fluoro-2-deoxyglucose (FDG)-PET computed tomography before surgery...

Oesophageal cancer is an aggressive disease. The possibility to early stratify patients as responsive and non-responsive with a non-invasive method is extremely appealing. The uptake of Fluorodeoxyglucose ((18)F-FDG) in tumours, provided by positron emission tomography (PET) images, has been proved to be useful to assess the initial staging of the disease, recurrence, and response to chemotherapy and chemo-radiotherapy (CRT). In the last years, efforts have been focused on the possibility to use ad interim (18)F-FDG-PET/CT (PETint) to evaluate response during radiation therapy...

Respiratory motion during PET/CT imaging can cause significant image blurring and underestimation of tracer concentration for both static and dynamic studies. In this study, with the aim to eliminate both intra-cycle and inter-cycle motions, and apply to dynamic imaging, we developed a non-rigid event-byevent (NR-EBE) respiratory motion compensated list-mode reconstruction algorithm. The proposed method consists of 2 components, the first component estimates a continuous non-rigid motion field of the internal organs using the internal-external motion correlation (NR-INTEX)...

Background: FDG-avid thyroid incidentalomas (TI) are seen in approximately 2.5% of patients imaged for staging or response assessment of malignancy and represent thyroid cancer in approximately 35% of cases. Consequently, the 2015 ATA guidelines strongly recommend investigation of all FDG-avid nodules ≥1cm with US and fine needle aspiration cytology (FNA). This study aims to assess the overall and thyroid cancer specific survival in a large cohort of patients with FDG-avid TI with long-term follow-up to assess the validity of this approach...
