18F-FDG PET/CT concurrent with first radioiodine post-therapeutic scan in high risk differentiated thyroid cancer: a useful tool or just an expensive diversion? [J]. Q J Nucl Med Mol Imaging, 2022. Doi: 10.23736/S182...
Imaging options: MRI, PET, CT scans can aid in identifying perineural spread of malignancies in the head and neckdoi:http://dermatologytimes.modernmedicine.com/node/366383High-tech imaging modalities are helpful in detecting metastatic neural spread of tumors, a p...
PURPOSE: Positron emission tomography (PET)/MRI combines the functional ability of PET and the high soft tissue contrast of MRI. The aim of this study was to assess contrast-enhanced (ce)PET/MRI compared to cePET/CT in patients with suspected recurrence of head and neck cancer (HNC). METHOD...
A novel imaging approach—68Ga-DOTATATE PET/CT—can more accurately differentiate residual/recurrent tumors from post-surgery scar tissue in patients with head and neck paragangliomas (HNPGLs) compared to MRI. Providing functional information about the tumors,68Ga-DOTATATE PET/CT has the potential t...
总之,对194例患者的研究结果显示,PET/CT和PET/MRI在肺癌的TNM分期方面的准确性相当;PET/CT对肺结节的检测具有优势,在以患者为单位进行分析时,PET/MRI对于肺部病灶特征显示与PET/CT具有同等价值。 3.胃肠道恶性肿瘤。(1)食管癌...
18F-FDG PET plays an increasing role in diagnosis and management planning of head and neck cancer. Hybrid PET/CT has promoted the field of molecular imaging in head and neck cancer. This modality is particular relevant in the head and neck region, given the complex anatomy and variable physiol...

Quantitative whole-body PET/MRI relies on accurate patient-specific MRI-based attenuation correction (AC) of PET, which is a non-trivial challenge, especially for the anatomically complex head and neck region. We used a deep learning model developed for dose planning in radiation oncology to deriv...
This study aimed to investigate the relationships among parameters from dynamic contrast-enhanced (DCE) MRI, diffusion-weighted MRI (DWI), and18F-fluorodeoxyglucose (18F-FDG) PET in patients with primary head-and-neck squamous cell carcinoma (HNSCC). A total of 34 patients with primary HNSCC unde...
Purpose: We evaluated the accuracy of 18FFDG PET/CT for the detection of recurrence or metastasis after treatment in patients with primary head and neck cancer, and compared the results with those of CT/MRI. Materials and Methods: We studied 34 patients with the diagnosis of head and neck ca...
