- Yearbook of Otolaryngology-Head and Neck Surgery 被引量: 1发表: 2006年 Preoperative evaluation of thyroid nodules with 18FDG-PET/CT or MIBI scan? We read with great interest the paper by Mitchell et al but we would like to suggest some considerations. There is no doubt that the main ...
Solitary plasmacytoma is an uncommon tumor of plasma cells that can appear in the head and neck. It must be differentiated from multiple myeloma because of its initial presentation. A case of solitary plasmacytoma on the palate is presented. Furthermore, role of F-18-fluorodeoxyglucose Positron Em...
The majority of primary and secondary malignant hepatic tumors show high FDG uptake, whereas most benign lesions have low uptake or that similar to background liver. However, false-negative and false-positive uptake can occur in such as low uptake in malignant tumors, and high uptake in benign...
To compare the diagnostic performance of ultrasound, contrast-enhanced computed tomography (CT) and 18F-FDG positron emission tomography (PET)/CT for detecting recurrent differentiated thyroid cancer in the neck. Methods Twenty patients who had undergone previous surgery for differentiated thyroid cancer ...
多发囊性结节伴甲状腺肿大,5例为囊壁环形钙化.结论 采取多层螺旋CT动脉期及延迟扫描,在CT表现上,甲状腺良,恶性结节具有一定特征性,结合综合征象,可提高CT诊断与鉴别诊断的准确性.%Objective To explore the value of the multi-slice spiral contrast-CT in the differentiation of benign from malignant thyroid ...
All the patients included for study of thyroid nodule either benign or malignant underwent DE-CT plain scan of the thyroid region in the neck. All nodules were confirmed by pathology, and with the diameter greater than 0.5 cm. On conventional CT images, analyzing the nodular morphology, ...
Adenoid cystic carcinoma (ACC) is a rare type of epithelial tumor mostly originated from salivary glands, accounting for 1% of total head and neck cancers [1, 2]. Histologically, ACC comprises tubular, cribriform, and solid patterns, and it is generally recognized that a solid growth pattern ...
PET/CT imaging emphasised (1) location (head, neck, body or tail) of pancreatic metastatic lesions. The PET/CT scans were compared with the corresponding CT images for accurate localisation of the tumours, and a consensus was reached for each scan; (2) the FDG uptake pattern of the ...
Conclusions Pre-ablative pertechnetate WBS with neck and chest SPECT/CT has good correlation for the detection of post-surgical thyroid remnant, cervical node and discrete lung nodule metastasis as compared to 131I WBS with SPECT/CT per-patient basis. Because 131I therapeutic activity is desired ...
If there is any focal increased uptake lesion detected in anterior neck on maximum intensity projection images by visual analysis, the uptake of thyroid nodule was verified by thorough examination of the axial PET/CT images by two nuclear medicine physicians. Then, SUVmax was measured for each ...
