Contrast-enhanced computed tomography (CT) is commonly used to identify lymph node metastasis; however, given the low sensitivity of CT, magnetic resonance imaging (MRI) is often used together with CT to stage cervical lymph nodes [9]. While MRI and CT are the most commonly used approaches ...
In contrast, ctDNA-positive patients who were treated with ACT had a significantly improved RFS than ctDNA-positive patients without ACT (p < 0.05). Similar results were observed when analyzed in AD and SqCC datasets separately (Supplementary Fig. 8). Therefore, postsurgical ctDNA status ...
Biopsy was obtained in 40 patients with suspicious lesions on PET-CT. In endoscopic examination; nasopharynx mucosal vegetan (meaning here is unclear) formation or submucosal asymmetry and fullness was considered as suspicious lesion. The presence of contrast enhancement in T2 in nasopharynx and neck...

While exploring this variety of MR based diffusion, perfusion and structural imaging tools, it is worth noting that assessing the dynamic visible ischemic tissue changes during the acute/subacute stages requires at least two parameters, with contrast based upon either the diffusion or perfusion ...
PET/CT does not exclude the need to undergo contrast-enhanced total body CT (TBCT) for most patients, since the morphological evaluation of most abdominal organs, mediastinal structures, and brain cannot be achieved with the use of PET/CT without intravenous injection. In addition, some lymphoma...
2.4. CT Scanning Protocol and Contrast Material Injection Protocol All patients were scanned with three types of multiple-detector row CT scanners: 16- and 64-multiple-detector CT scanners (Siemens, Erlangen, Germany); 64-General Electric CT scanners (GE Healthcare, Milwaukee, WI). The scanning...
Most people with good sense would accept that we can and should learn from accidental failures. It would be impossible to progress in anything, after all, without taking the occasional misstep. And by understanding how we slipped, we can avoid falling in the future. Few would advocate making...
