An adult patient presented with acute severe pelvic and low-back pain. Evaluations with CT and MRI were negative/inconclusive. F-18 FDG PET/CT localized the site of pathology in right sacroiliac-joint by demonstrating hypermetabolic activities conformal with the joint's outline, signifying infectious/inflammatory sacroiliitis. Blood culture was positive for Group B streptococcus (GBS). Antibiotic treatment was started within 24 hours from onset of symptoms, and there was almost immediate partial pain relief. GBS sacroiliitis is a rare form of septic sacroiliitis requiring prompt diagnosis and urgent treatment. This is the first report of F-18 FDG PET/CT for diagnosing GBS sacroiliitis in adults with no predisposing factors.

Background: We recently reported that subjects who had worsening sleep over time had a clear worsening of both memory and brain metabolism compared to subjects whose sleep improved over time, and metabolic decline was particularly significant in the posterior cingulate cortex (PCC) (Alzheimer's Dement. 2023; 19(Suppl. 24):e082867), an area of the brain that metabolically declines in the earliest stages of Alzheimer's disease.

Department of Nuclear Medicine and Biomedical Research Institute, Pusan National University Hospital, Busan, Republic of Korea.
Background: Despite TSH suppressive therapy improve the prognosis for the patient with differentiated thyroid cancer (DTC), there is an increasing concern regarding the potentially harmful effects of lifelong TSH suppression. Therefore, we aimed to examine the changes in body composition under TSH suppression in postmenopausal women with DTC.
Methods: The body composition was assessed by the volumes as following; fat tissues of the epicardium and abdominal visceral and subcutaneous areas; bilateral psoas muscle or thigh muscle.
Prognostic value of pseudotime from texture parameters of FDG PET/CT in locally advanced rectal cancer with neoadjuvant concurrent chemoradiotherapy.

Department of Nuclear Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-Ro, Gangnam-Gu, Seoul, 06351, Republic of Korea.
Texture analysis generates image parameters from F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Although some parameters correlate with tumor biology and clinical attributes, their types and implications can be complex. To overcome this limitation, pseudotime analysis was applied to texture parameters to estimate changes in individual sample characteristics, and the prognostic significance of the estimated pseudotime of primary tumors was evaluated.

Background: To intraindividually compare the diagnostic performance of positron emission computed tomography (F-18-FDG-PET/CT) and diffusion-weighted magnetic resonance imaging (DW-MRI) in a non-inferiority design for the discrimination of peripheral nerve sheath tumours as benign (BPNST), atypical (ANF), or malignant (MPNST) in patients with neurofibromatosis type 1 (NF1).
Results: In this prospective single-centre study, thirty-four NF1 patients (18 male; 30 ± 11 years) underwent F-18-FDG-PET/CT and multi-b-value DW-MRI (11 b-values 0 - 800 s/mm²) at 3T. Sixty-six lesions corresponding to 39 BPNST, 11 ANF, and 16 MPNST were evaluated.
Does FDG PETCT have a predictive value for neoadjuvant chemotherapy response in nonmetastatic breast cancer?
Ir J Med Sci
December 2024
Department of Medical Oncology, Karadeniz Technical University, Trabzon, Turkey.
Background: A pathological complete response (pCR) rate after neoadjuvant chemotherapy (NAC) is important for the prognosis of early-stage breast cancer. The prediction of an NAC response plays a key role in managing neoadjuvant treatment.
Aims: The aim of this study is to investigate the predictive value of the baseline PETCT FDG (F-18 fluoro-deoxy-glucose (FDG) positron emission tomography/computed tomography) SUVmax (the maximum standardized uptake value) for pCR after NAC in early-stage breast cancer.
