Two distinct types of systemic amyloidosis—transthyretin (ATTR) and light chain (AL)—account for the majority cardiac amyloidosis (CA), which have been considered mutually exclusive. Diagnostic confusion can arise when both proteins are identified from an amyloid deposit. We present a rare occurrence histopathologically confirmed concomitant ATTR AL CA captured on 99m Tc-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) scan 18 F-flutemetamol (FMM) PET/CT.
Background/Objectives This study aimed to evaluate whether very early interim 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/computed (CT) after a single cycle of first-line chemotherapy predicts long-term survival outcome in patients with diffuse large B-cell lymphoma (DLBCL). Methods A total 51 (31 males and 20 females; mean age 55 years) had four FDG PET/CT studies, at baseline one, three, six cycles (PET0, PET1, PET3, PET6). Visually quantitatively assessed PET...
To evaluate the clinical significance of incidental focal prostate fluorodeoxyglucose (FDG) uptake, we reviewed 18-F-FDG positron emission tomography (PET)/CT scans from 2003 to 2007 and selected cases with FDG uptake in prostate. Cases known cancer were excluded. The maximum standardised value (SUV(max)), site (central or peripheral) pattern (discrete ill-defined) calcification (present absent) volume (<30 ≥30 cc) recorded. PET/CT findings correlated serum prostate-specific antigen (PSA)...
Total Lesion Glycolysis Using 18 F-FDG PET
To evaluate the prognostic value of metabolic tumor volume (MTV) and maximum standardized uptake (SUVmax) on initial positron emission tomography-computed tomography (PET-CT) investigate clinical SUVmax for early detection locoregional recurrent disease after postoperative radiotherapy in patients with locally advanced head neck squamous cell carcinoma (HNSCC).A total 100 HNSCC received primary excision dissection followed by adjuvant or without chemotherapy. The MTV were measured from sites...
Whether FDG PET/CT can replace bone marrow biopsy (BMBx) is undecided in patients with diffuse large B cell lymphoma (DLBCL). We compared the visual PET findings and radiomic features, BMBx results. A total of 328 were included; 269 (82%) PET-negative 59 (18%) PET-positive for lesions on assessment. fair degree agreement was present between (ĸ = 0.362, p < 0.001). Bone involvement lead to stage IV 12 patients, despite no other evidence extranodal lesion. Of 35 discordant BMBx-negative cases,...
Objectives The purpose of this study was to evaluate the clinical value preoperative [18F]fluoro-2-deoxy-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT) by comparing it neck sonography in papillary thyroid carcinoma. Methods diagnostic accuracies PET/CT and for detecting cervical node metastasis were compared. association between FDG uptake primary tumor prognostic factors differentiated cancer, such as size, multiplicity, extrathyroid extension, lymph metastasis,...
F-18-fluoro-2-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is essential for monitoring response to treatment in patients with diffuse large B-cell lymphoma (DLBCL) and qualitative interpretation commonly applied clinical practice. We aimed evaluate the interobserver agreements of PET/CT DLBCL predictive value results outcome. images were obtained 3 times: at baseline, after cycles first-line chemotherapy (interim), completion chemotherapy. Two nuclear medicine...
Abstract Although differentiation between central chondroid tumors is important, their parallelism makes it a diagnostic conundrum for clinicians and radiologists. The objective of this study was to evaluate the efficiency quantitative single photon emission computed tomography (SPECT)/computed (CT) in differentiating grade I chondrosarcomas from enchondromas. We reviewed SPECT/CT images patients with enchondromas arising long bones. Volume, mean standardized uptake value (SUVmean), maximum...
Muscular Sarcoidosis Detected by F-18 FDG PET/CT in a Hypercalcemic PatientSarcoidosis is systemic granulomatous disease of unknown etiology that involves many organs, occasionally mimicking malignancy.We herein report 50-yr-old woman muscular sarcoidosis chronic myopathic type, manifested hypercalcemia and muscle wasting.Besides insignificant hilar lymphadenopathy, her was confined to generalized atrophic muscles therefore, alone among conventional imaging studies provided diagnostic clues...
We evaluated the suitability of 18F-fluorodeoxythymidine (18F-FLT) positron emission tomography (PET)/computed (CT) for assessment early response to induction therapy and its value predicting clinical outcome in patients with acute myeloid leukemia (AML). Adult who had histologically confirmed AML received were enrolled. All underwent 18F-FLT PET/CT after completion induction. images visually quantitatively assessed. Cases intensely increased bone marrow uptake more than one third long bones...
We aimed to evaluate the prognostic value of early response assessment using a volumetric fluorine-18-fluorodeoxyglucose (F-FDG) PET analysis in chemotherapy-treated patients with non-small-cell lung cancer (NSCLC).We retrospectively reviewed 33 NSCLC who received first-line chemotherapy and performed F-FDG PET/computed tomography before (baseline PET) after two cycles (interim PET). The maximum standardized uptake (SUVmax) metabolic tumor volume (MTV) total malignant lesion were measured...
Castleman disease (CD) is a relatively rare lymphoproliferative disorder and the pathophysiology of subtypes are incompletely understood. Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed (CT) demonstrates metabolic activity inflammatory tumorous conditions. The FDG uptake intensity sites involved lesions on PET/CT were assessed by histologic subtypes, compared to patient’s hemoglobin, platelet, albumin, high-sensitivity C-reactive protein (hs-CRP) levels. In...
Pressure sensors that detect mechanical deformation are essential components of wearable ionotronics. In this study, we investigate the correlation between characteristics polymeric ion conductors (termed gels) and ionotronic sensory performance. Film-type gels straightforwardly created using a one-step photogelation strategy, their tuned by manipulating fundamental parameters. The gel properties optimized for pressure sensors, high ionic conductivity is determined to be primary physical...
Abstract Background Head motion during brain positron emission tomography (PET)/computed (CT) imaging degrades image quality, resulting in reduced reading accuracy. We evaluated the performance of a head correction algorithm using 18 F-flutemetamol (FMM) PET/CT images. Methods FMM images were retrospectively included, and PET reconstructed algorithm: (1) estimation through 3D time-domain signal analysis, smoothing, calculation motion-free intervals Merging Adjacent Clustering method; (2)...
Accurate quantification of amyloid positron emission tomography (PET) is essential for early detection and intervention in Alzheimer’s disease (AD) but there still a lack studies comparing the performance various automated methods. This study compared PET-only method PET-and-MRI-based with pre-trained deep learning segmentation model. A large sample 1180 participants Catholic Aging Brain Imaging (CABI) database was analyzed to calculate regional standardized uptake value ratio (SUVR) using...
