Magnetic resonance imaging (MRI) has become an essential imaging modality in both staging and targets volume (TV) delineation for head and neck (H&N) cancer radiotherapy (RT) owing to its intrinsically superior soft-tissue contrast, functional information, high resolution and non-radiation [1,2,...

Ultrasound is the second most common method of imaging carried out in hospitals worldwide after plain-film radiography. Modern high-resolution ultrasound has excellent spatial and contrast resolution for the near field, and the development of 3D technolo
Some soft-tissue neck abnormalities are best assessed with neither x-ray nor CT but rather with ultrasound, magnetic resonance imaging (MRI), fluoroscopy, or techniques such as bronchoscopy and esophagoscopy. First we consider some general principles regarding the available imaging modalities: x-ray...
increased soft tissue contrast allowing improved diagnostic performance compared with MR imag[1] ing alone or PET/CT alone (diagnostic accuracy of 0.926 vs 0.836 and 0.847; P<.05, respectively).6A potential drawback of PET/MR imaging is the ...
In contrast, the sensitivity (100%), NPV (100%), and accuracy (82.8%) of DHGC imaging in the coincidence mode were superior to that of CT/MRI. Dual-head gamma-camera imaging in the coincidence mode had a specificity (58.3%) and PPV (77.3%) comparable to those of CT/MRI. Our data...
When visualized with MRI, mechanical issues rarely present themselves. You may see an image of a bulging disc, but that does not tell the full story of your back pain. By contrast, diagnostic ultrasonography resolution is up to 100X higher than MRI for visualizing superficial connective tissues....
