Findings In this prospective, paired, noninferiority cohort study, a total of 172 consecutive patients with primary hyperparathyroidism underwent scintigraphy followed by ultrasonography and contrast-enhanced ultrasonography by a blinded surgeon-sonographer. The study found that ultrasonography, both...
Conclusions In contrast to steel retainers, titanium and gold retainers are fully compatible for both head/neck and dental MRI when using MSVAT-SPACE. Clinical relevance This study demonstrates that titanium and gold retainers do not impair the diagnostic quality of head/ neck and dental ...
Kanda et al,15 2013 Retrospective 30 MRI 67–87* 90* Chaput et al,16 2018 Retrospective 35 MRI 83 63 N Staging By contrast, most studies show that the sensitivity of CT and/or MRI alone in detecting nodal involvement is relatively poor and 18F-FDG PET significantly outperforms cross-secti...
Fig. 16.Elevated 18F-FDG activity of large nasopharyngeal mass (asterisk) in axial PET/CT (A), axial contrast[1] enhanced CT (B), and axial contrast-enhanced T1-weighted (C) obscures a left retropharyngeal lymph node (C, arrow). (From Purohit, B. S., Ailianou, A., Dulguerov, ...
MRI separately to help the delineation (if they felt it necessary to consult to MRI). Hence, the “gold standard” OAR references could be viewed as human experts contouring using both CT and MR information. In contrast, SOARS is trained using only CT images (with the “gold standard” ...
Background: In contrast to non-invasive implants, invasive implants of serous borderline tumor/atypical proliferative serous tumor (SBT/APST) are associated with adverse clinical outcome and currently classified as low-grade serous carcinoma by the 2014 WHO classification. Somatic mutations in KRAS and...
In contrast, Tsan et al. reported a higher rate of mucositis and overall toxicity in the weekly cisplatin group [34]. Also the recent comparative analysis of different prospective trials showed less toxicities with the 3-weekly regimen [18]. The fact that this is a retrospective study limits ...
The accuracy was not enhanced by fusing CT with 18 FDG-PET or MRI with 18 FDG-PET. Conclusions: The detectability threshold of occult metastases appears to be below the spatial and contrast resolution of CT, MRI, and 18 FDG-PET. The decision for eND in patients with cT1-T2 cN0 cM0 ...
Confident scoring rate in malignant concordant cases was higher on PET/MRI (96.6%, 57/59) than on MRI (76.3%, 45/59) (p = 0.003). In conclusion, compared with PET or MRI alone, PET/MRI presents better diagnostic performance in accuracy and confidence for diagnosis of malignancy. ...
Each OPC patient was closely followed-up at regular intervals every 2–3 months during the first 2 years, then every 3–6 months during Years 3–5 post-treatment. Locoregional imaging studies (contrast-enhanced CT with or without MRI or PET-CT scans) were requested on a regular basis and/...
