这些淋巴结位于咽后间隙,从第一颈椎(外侧块)的上边缘向颅侧延伸到尾侧舌骨体的颅侧(图)。 这个空间的前面是咽缩肌,后面是头长肌和颈长肌。 从侧面看,咽后淋巴结受限于颈内动脉的内侧边缘。 咽后淋巴结接收来自鼻咽粘膜、咽鼓管和软腭的传出淋巴管。 这些淋巴结有转移鼻咽癌、咽后壁和口咽癌(主要是扁桃体...
In recent years, there has been much research into ultrasound of the maxillofacial region, and it has been found to have a range of unique applications, including the evaluation of cervical lymph nodes and the detection of space infections and cystic and solid lesions of the head and neck. ...

Magnetic resonance imaging (MRI) is known for its excellent soft tissue contrast, which is based on nuclear magnetic resonance of (proton) spins without the need for ionizing radiation. Throughout the history of MRI, continuous efforts were made to accelerate the time-intensive examinations. After ...
Convolutional neural network (CNN), a class of artificial neural networks that has become dominant in various computer vision tasks, is attracting interest across a variety of domains, including radiology. CNN is designed to automatically and adaptively learn spatial hierarchies of features through back...
A 54-year-old woman with metastatic cervical carcinoma. T1-weighted (A), T2-weighted (B), and diffusion weighted (C) images show two enlarged metastatic left pelvic sidewall lymph nodes (arrows). The metastatic nodes are bright and are more conspicuous on the diffusion-weighted image. On ...
A detail view from a frontal chest radiograph shows bilateral cervical ribs (arrows) arising from the seventh cervical vertebral body . The sternum forms the anterior midline portion of the thoracic cage. It is made up of the manubrium, which articulates with the clavicles; the body; and ...
PET/CT using18F-FSU-880 in a 71-year-old man with biochemical recurrence after total prostatectomy (pT2bN0, Gleason score 4 + 3). PSA level increased to 2.10 ng/ml. Focal uptake was observed in a left obturator lymph node (SUVmax; 10.2). Salvage radiation therapy had been consider...

Node-RADS can be used and reported in addition to already existing RADS (e.g., LI-RADS or PI-RADS). An exception is NI-RADS in the surveillance of head and neck cancer, where a score is already assigned for the cervical lymph nodes (“neck”). The criteria and algorithm of Node-RAD...
