The appearance of new plasmacytoma and/or osteolytic bone lesion is one of the criteria defining relapse (or refractory MM) [70] and both the IMWG and EHA-ESMO Clinical Practice Guidelines recommend WB-LDCT (or a localized CT in case of symptoms) when relapse (or progressive disease) is su...
The MIP image (A) of the patient displayed multiple extracranial lesions with increased FDG uptake in addition to the intracranial lesion. Axial 18F-FDG PET/CT images revealed FDG-avid enlarged infundibulum (B, C and D) ,an enlarged nodule on left neck (IIA) (E, F, and G), left ...
When a 2-[18F]FDG-avid breast lesion is incidentally detected in a study performed for reasons other than BC, further characterization with diagnostic mammography and/or breast US should be performed because these lesions are malignant in 30–40% of cases [62,63]. Several aetiologies have been...
Confirming that the primary malignancies were FDG-avid, further evaluation of the solitary bony FDG-avid lesions was carried out by conventional imaging, follow-up and biopsy studies. Spontaneous resolution of a lesion on subsequent PET-CT without a change in therapy was considered benign while ...
lesion-to-liver and lesion-to-blood pool ratios.Results. Among the 19 analyzed patients, the positive rate of the PET/CT image was 94.7% (18/19), with 1 false negative (5.3%, 1/19) case occurring in the cutaneous LCH. Among the 76 lesions, 69 were FDG-avid lesions (69/76, 90.8...
The specificity of CE-PET-CT cannot be determined from patient-level data, because CE-PET-CT yielded a false-positive lesion in a patient who also had other, true metastases. Conclusions: CE-PET-MR detected a higher number of osseous metastases than did same-day CE-PET-CT, and was ...
Several lesions demonstrated decreased 18F-FLT accumulation (lower than the surrounding bone marrow) in anatomical sites that corresponded to focal, 18F-FDG avid, osteolytic lesions (Fig. 5). The Yang test showed that the number of 18F-FDG avid, focal, MM-indicative lesions was significantly ...
Diagnostic importance of 18F-FDG PET/CT parameters and total lesion glycolysis in differentiating between benign and malignant adrenal lesions PURPOSE: Benign adrenal lesions are prevalent in oncologic imaging and make metastatic disease diagnoses difficult. This study evaluates the diagnostic imp... Ciftci...
F-18-FDG PET/CT demonstrated mildly FDG-avid lymph nodes consistent for chronic lymphocytic leukemia, as well as FDG-avidity in the right femoral head with corresponding osteopenia, rather than a focal lytic lesion. MR demonstrated bone marrow edema consistent with TOH. TOH is benign and self-...
PET/CT confirmed presence of left humeral lesion and revealed an FDG avid 3.2 脳 1.3 cm pleural thickening in the left posterolateral lung and base (Figure 1C). Minimal left pleural effusion was also described. Although rare, few cases of pleural effusion in pulmonary LCH have been reported....
