Treatment management in cases of head and neck squamous cell cancer (HNSCC) that are clinically negative for lymph node metastases (cN0) is still an important topic discussion. There increasing interest sensitive imaging modalities can detect the risk occult at levels below 20%. This study aimed to examine efficacy integrated positron emission tomography (PET)/magnetic resonance (MRI) determining nodal metastasis status cN0 patients with HNSCC.In this retrospective study, 44 who underwent...
Regular follow-up of patients with lung cancer treated surgically is crucial to detect local recurrence or distant metastasis the tumor. Postoperative follow-ups are performed thorax computed tomography (CT) and, if necessary, positron emission (PET)/CT. Sometimes, inflammatory tissue reactions due materials used during surgery for hemostasis may cause appearance tumor in imaging modalities. In this study, we presented that oxidized regenerated cellulose (ORC) intraoperatively false on...
We aimed to evaluate the relationship between sarcopenia, myosteatosis, and systemic inflammatory response biomarkers their prognostic role in stage 2 3 gastric cancer patients.This study included 84 patients with or who underwent a gastrectomy. Computed tomography scans were used determine skeletal muscle index (SMI) at third lumbar vertebra level for sarcopenia myosteatosis.Based on Asian Working Group of Sarcopenia (AWGS2019) criteria, incidence was 36.9% that myosteatosis 46.4%....
Abstract Although PSMA-targeted PET imaging is predominantly used for prostate carcinoma (PC), it has also been reported thyroid (TC). A 77-year-old man had a liver metastasectomy poorly differentiated TC, which elevated 18 F-FDG uptake. Two years later, he was diagnosed with acinar-type modified Gleason score of 7 (3 + 4) PC. Four metastatic lesions that no radioactive iodine and avidity. These were 68 Ga-PSMA avid, the biopsy confirmed TC metastasis. This case emphasizes importance...
Sometimes, the underlying causes of inflammation cannot be established despite meticulous investigation, including medical history, physical examination, laboratory tests, and radiologic procedures. Rheumatologists are often faced with patients whose condition is known as unknown origin (IUO). Differential diagnosis IUO diverse, investigation these cases challenging time-consuming.The study aimed to assess diagnostic role positron emission tomography/computed tomography (PET/CT) in...
Objective To evaluate the diagnostic accuracy of 68gallium (68Ga) prostate-specific membrane antigen (PSMA) positron emission tomography/magnetic resonance imaging (PET/MRI) and multiparametric MRI (mpMRI) by region-based comparison index tumour localisations using histopathological maps patients who underwent radical prostatectomy because clinically significant prostate cancer. Patients Methods The study included 64 after primary staging with mpMRI 68Ga-PSMA PET/MRI. Diagnostic analysis was...
The aims of our study were to compare F-18 fluorodeoxyglucose (FDG) positron-emission tomography/magnetic resonance imaging (PET/MRI) and PET/computed tomography (CT) in pediatric oncology patients terms anatomic correlation FDG-positive lesions, also diffusion-weighted (DWI) with PET assess the between apparent diffusion coefficient (ADC) values standardized uptake value (SUV). Sequential PET/CT PET/MRI images and/or whole-body DWI ADC mapping 34 retrospectively analyzed. lesions visually...
Purpose We aimed to explore the utility and additional clinical contribution of brain fluorodeoxyglucose (FDG) PET imaging for assessment children with possible autoimmune encephalitis in comparison MRI. Materials methods conducted a retrospective analysis six pediatric patients (all seronegative) between 2014 2019 initial diagnosis who had FDG PET/CT or PET/MRI MRI during diagnostic period. Diagnosis was based on consensus criteria defined by Graus et al . Brain images were visually...
Abstract Background The aim of this study was to evaluate the role histopathological and biochemical parameters in prediction presence number PSMA positive lesions consistent with metastatic spread prostate cancer on 68 Ga‐PSMA PET images. Methods Biochemical, imaging data 302 patients who underwent Ga‐PSMA‐11 PET/CT or PET/MR for primary staging were retrospectively analyzed. Patients divided into two groups as “PET positive” negative” according pathologic extraprostatic involvement....
Purpose The aim of this study was to investigate the role histopathologic and biochemical parameters for predicting 18 F-FDG PET positivity primary staging in patients with newly diagnosed testicular germ cell tumors (TGCT). It also aimed evaluate prognostic value derived metabolic features patient group. Materials methods imaging findings 51 who were as TGCT underwent PET/CT after surgery between 2009 2019 evaluated retrospectively. In terms presence uptake consistent metastasis, divided...
The aim of this study was to evaluate the prognostic value textural parameters primary tumors, serum lactate dehydrogenase (LDH), D -dimer, and ferritin in high-risk neuroblastoma patients.The imaging findings 22 patients (14 girls 8 boys; age, 36.6 ± 34.2 [range: 5 138] months) who underwent 18-fluorodeoxyglucose positron emission tomography/computed tomography for staging before therapy between 2009 2020 were retrospectively evaluated. Positron tomography-derived metabolic data (maximum...
