Cooccurrence of Capsular Liver Lesions Along with Peritoneal Carcinomatosis and Hematogenous Metastases in Ovarian Cancer Patients on Consecutive F-FDG PET/CT Studies.

Objectives: The aim of our study was to evaluate the cooccurrence of capsular liver lesions along with peritoneal carcinomatosis and hematogenous metastases in other regions of the body in ovarian cancer patients on follow-up F-18 fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) studies.

Methods: Consecutive F-FDG PET/CT studies of 54 women with ovarian cancer between August 2012 and January 2020 and a total of 192 scans were analysed retrospectively. All patients had at least one hepatic and/or capsular lesion with high F-FDG uptake and at least two PET/CT examinations.

Enhancing PSMA PET/CT imaging of prostate cancer: investigating the impact of multiple time point evaluation, diuretic administration, cribriform pattern, and intraductal carcinoma.

Objective: Our objective was to correlate staging PSMA PET imaging parameters to final histopathology. Second objective was to assess the performance of standard versus delayed PSMA PET to detect primary prostate tumor.

Methods: Thirty-one patients (mean age, 61.

Optimizing the Personalized Care for the Management of Rectal Cancer: A Consensus Statement.

Colorectal cancer is the third most common cancer in Turkey. The current guidelines do not provide sufficient information to cover all aspects of the management of rectal cancer. Although treatment has been standardized in terms of the basic principles of neoadjuvant, surgical, and adjuvant therapy, uncertainties in the management of rectal cancer may lead to significant differences in clinical practice.

Physiological fluorodeoxyglucose uptake of spinal cord in adults.

Objective: Physiological fluorodeoxyglucose (FDG) uptake of spinal cord needs to be correctly recognized during evaluation of whole-body PET scans, especially for oncological cases. Our aim was to analyze physiological cord FDG uptake and its relation to gender, age, body weight, environmental temperature and time to imaging.

Materials And Methods: PET scans of 254 patients in a single year, one patient for every working day were retrospectively selected.

Findings of Gynecomastia That Developed in Follow-up Secondary to Bicalutamide Treatment on Bone Scan.

Prostate cancer is a common neoplastic disease especially in elder patients. Metastatic prostate disease has low five-year survival rate. Bicalutamide is an androgen receptor antagonist that acts as an inhibitor by competizing androgen receptors in the target tissue and used as a treatment option in prostate cancer.

Effectiveness of the addition of the brain region to the FDG-PET/CT imaging area in patients with suspected or diagnosed lung cancer.

Purpose: We aimed to evaluate the effectiveness of the brain region imaging in FDG-PET/CT scanning of patients with suspected or diagnosed lung cancer.

Materials And Methods: We performed the study retrospectively on the medical charts of 427 patients. We divided the FDG-PET/CT field of view (FOV) into four major imaging regions: brain, head-neck, abdomen and pelvis.

What approach should we take for the incidental finding of increased 18F-FDG uptake foci in the colon on PET/CT?

Introduction: F-Fluorodeoxyglucose (F-FDG) PET/CT represents an imaging modality that is gaining increasingly more prominence in screening, staging, and therapeutic monitoring of malignant diseases. An incidental focus of uptake in different regions of the body is not an uncommon finding during PET/CT imaging. Patients with incidental gastrointestinal tract findings comprise ∼3% of the overall patient group.

Unexpected Uptake by the Gallbladder in Post-Ablative I-131 Scan.

A 47-year-old woman was diagnosed as papillary thyroid carcinoma. I-131 ablation therapy was applied following total thyroidectomy, and the whole-body scan revealed a focus of increased uptake in the right upper quadrant. Lateral view images of the uptake site showed that the focus was located near the right liver lobe.

Evaluation of clinical contributions provided by addition of the brain, calvarium, and scalp to the limited whole body imaging area in FDG-PET/CT tumor imaging.

Purpose: The aim of this study was to detect additional findings in whole body FDG-PET/CT scan including the brain, calvarium, and scalp (compared to starting from the base of the skull) in cancer patients and to determine contributions of these results to tumor staging and treatment protocols.

Materials And Methods: We noted whether the findings related to the brain, calvarium, and scalp in 1359 patients had a potential to modify staging of the disease, chemotherapy protocol, radiotherapy protocol, and surgical management. We identified rates of metastatic findings on the brain, calvarium, and scalp according to the tumor types on FDG-PET/CT scanning.

18F-FDG PET/CT findings of radiotherapy-related myocardial changes in patients with thoracic malignancies.

Objective: The purpose of this study was to investigate myocardial findings of F-fluorodeoxyglucose PET/computed tomography (F-FDG PET/CT) after thoracic radiotherapy.

Methods: F-Fluorodeoxyglucose PET/CT examination was performed in 38 patients at least 4 months after radiotherapy. Patients with known cardiac diseases, high cardiovascular risk factors, or diabetes mellitus were excluded.

The role of positron emission tomography/CT in hypoxic ischaemic encephalopathy in children.

The role of positron emission tomography/CT (PET/CT) in diagnosis and follow-up of newborns with hypoxic ischaemic encephalopathy has been documented before; however, this is the first presentation of elder children with both diagnostic and follow-up PET/CT results as far as we know.

Incidental detection of pericardial effusion on bone scan.

The patient was a 57-year-old man with lung cancer. He was referred to nuclear medicine department for the evaluation of bone metastases. Bone scintigraphy was performed with 99mTc-labeled HDP.

PET/CT images of a patient with haemophagocytic lymphohistiocytosis.

Haemophagocytic lymphohistiocytosis (HLH) is a rare immune disorder that predominantly affects macrophages and T lymphocytes and leads to multiple organ disease and death. The characteristic pathological finding in the bone marrow and the other affected tissues is haemophagocytosis of macrophages (macrophages digesting erythrocyte). Primary (hereditary) and secondary (acquired) forms of the disease are present.

Detection of previous brain infarct on PET/CT study of a Hodgkin lymphoma patient.

Positron emission tomography/CT examination was performed to 62-year-old male patient with diagnosis of Hodgkin lymphoma for treatment response which revealed complete response. During re-evaluation process of this patient in our department, asymmetrical brain metabolism defect of right thalamus and hipometabolism of right parietal lobe was observed. This finding was confirmed with additional CT imaging as a subacute infarct tissue.

Liver schwannoma incidentally discovered in a patient with breast cancer.

Background: Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer.
